Labor litigation in Thailand sits at the intersection of three statutes — the Labor Protection Act B.E. 2541 (1998), the Labor Relations Act B.E. 2518 (1975), and the Act on Establishment of Labor Courts and Labor Court Procedures B.E. 2522 (1979) — together with the inquisitorial procedure of the Thai Labor Court, the alternative dispute-resolution machinery operated by the Department of Labor Protection and Welfare (DLPW) under the Ministry of Labor, and a body of Dika (Supreme Court) jurisprudence that has shaped how each provision is applied in practice.

For Thai and foreign employers alike, understanding this framework is essential before a dispute crystallizes. Labor cases are heard by specialist judges, are exempt from court fees, are subject to mandatory in-court mediation, and proceed under an inquisitorial procedure in which the judge personally questions every witness. Appeals lie on points of law only. The financial exposure of a wrongful termination is governed by a precise statutory matrix of severance pay, pay in lieu of notice, and damages for unfair dismissal under Section 49 of the Labor Court Establishment Act, and that matrix is reinforced by a fifteen-per-cent annual interest surcharge under Section 9 of the Labor Protection Act for sums withheld without reasonable cause. On the regulatory side, the LPA imposes a layered system of criminal penalties on employers under Sections 144 to 159, ranging from a fine of two thousand baht for procedural infringements to imprisonment of up to one year and fines of up to two hundred thousand baht for substantive breaches that cause physical or psychological harm to an employee.

This guide explains, in practitioner-grade detail, the law and procedure of labor litigation in Thailand: the courts and their jurisdiction; the two parallel routes for resolving a dispute (the Labor Inspector and the Labor Court); statutes of limitation; the procedure before the Labor Court from filing through mediation, trial, judgment, appeal, and enforcement; the substantive entitlements that drive most labor claims (severance pay, pay in lieu of notice, damages for unfair dismissal, special severance for relocation and technology-driven layoffs, the Section 75 LPA seventy-five-per-cent wage rule for temporary business suspensions, working-hour and overtime entitlements, probationary employees, fixed-term contracts, constructive dismissal, and anti-discrimination protections); the complete schedule of criminal penalties applicable to employers under Sections 144 to 159 LPA; the parallel procedures before the Workmen’s Compensation Fund and the Social Security Office; and recent Supreme Court guidance. It draws on the consolidated text of the relevant Acts as published by the Office of the Council of State and the Ministry of Labor, on the official guidance of the Central Labor Court (San Raeng-ngan Klang), on Supreme Court decisions from 2561 (2018) onward, and on the joint guidebook of the International Organization for Migration (IOM) and the DLPW, “Business Guidebook: How to Mediate Employment Disputes Under Thai Labour Law” (2021).

The Legal Framework Governing Labor Disputes in Thailand

Four statutes form the spine of Thai labor litigation:

1. The Labor Protection Act B.E. 2541 (1998) (พระราชบัญญัติคุ้มครองแรงงาน พ.ศ. 2541), or “LPA”, is the primary statute regulating the substantive employment relationship. It defines wages, working hours, leave entitlements, the conditions of termination, severance pay, and the powers of the Labor Inspector. The LPA has been amended several times, most consequentially by Act No. 7 of B.E. 2562 (2019), which introduced the 400-day severance bracket for employees with twenty or more years of service, codified pay in lieu of notice under Section 17/1, and increased the statutory interest rate for unpaid statutory monies under Section 9 from 7.5 per cent to 15 per cent per annum. The official Thai text is published in the Royal Gazette at ratchakitcha.soc.go.th.

2. The Labor Relations Act B.E. 2518 (1975) (พระราชบัญญัติแรงงานสัมพันธ์ พ.ศ. 2518), or “LRA”, regulates the collective relationship between employers and employees — unions, employee committees, collective bargaining agreements, strikes and lockouts, the Labor Relations Committee (Khana Kammakan Raeng-ngan Samphan), and unfair labor practices. The Senate consolidated reprint is available at senate.go.th.

3. The Act on Establishment of Labor Courts and Labor Court Procedures B.E. 2522 (1979) (พระราชบัญญัติจัดตั้งศาลแรงงานและวิธีพิจารณาคดีแรงงาน พ.ศ. 2522), or “LCEPA”, constitutes the Labor Court and prescribes a specialized procedure that departs from the ordinary civil-procedure regime in important respects (no court fees, mandatory mediation, an inquisitorial evidence regime, restricted appeals on points of law only). The Ministry of Labor publishes a current consolidated text at mol.go.th.

4. The Civil and Commercial Code (CCC), Book III, Title VI — Hire of Services (Sections 575 to 586) — supplies the common-law underpinnings of the employment contract where the LPA is silent, and remains directly applicable for matters such as the basic definition of “employment” and the residual ten-year prescription under Section 193/30. See Thai Civil and Commercial Code.

Several specialist Acts overlap with these four. The Social Security Act B.E. 2533 (1990) governs social-security contributions and the unemployment, sickness, maternity, child-allowance, invalidity, old-age, and survivor benefits administered by the Social Security Office. The Workmen’s Compensation Act B.E. 2537 (1994) (as amended by Act No. 2 of B.E. 2561 (2018)) governs employer liability for injury, illness, disability, or death arising out of and in the course of employment. The State Enterprise Labor Relations Act B.E. 2543 (2000) applies to state-enterprise employees. The Maritime Labor Act B.E. 2558 (2015) applies to seafarers on Thai-flagged vessels, and the Supreme Court has confirmed that the Labor Court’s Section 8(2) jurisdiction extends to disputes arising under it (Supreme Court Decision No. 2868/2566). The Working of Aliens Emergency Decree B.E. 2560 (2017) regulates the right of foreign nationals to undertake employment in Thailand. The Home Workers Protection Act B.E. 2553 (2010) protects out-workers performing industrial work in their own homes, and the Working from Home Act B.E. 2566 (2023) regulates remote work for office-based employees who agree with their employer to work outside the workplace.

The Thai Labor Court System: Structure and Jurisdiction

The Central Labor Court and the Regional Labor Courts

Labor cases in Thailand are heard by specialist labor courts, not by the ordinary Civil Court. The Central Labor Court (San Raeng-ngan Klang) sits in Bangkok and, under Section 5 LCEPA, has territorial jurisdiction throughout Bangkok Metropolis and the surrounding provinces of Samut Prakan, Samut Sakhon, Nakhon Pathom, Nonthaburi and Pathum Thani. Nine Regional Labor Courts cover the rest of the country (Chiang Mai, Lampang, Nakhon Ratchasima, Udon Thani, Khon Kaen, Ubon Ratchathani, Songkhla, Surat Thani, and Rayong, each established by Royal Decree and seated in the regional capital). The court’s website is operated by the Office of the Judiciary at lbc.coj.go.th.

For the purpose of choosing the proper venue, Section 33 LCEPA permits the claimant to file in the Labor Court of the territory in which (a) the cause of action arose, which the Act deems to be the employee’s place of work, or (b) the plaintiff is domiciled, or (c) the defendant is domiciled. In practice, the place of work is the most common venue because it is where evidence and witnesses are located.

Composition of the Panel: One Career Judge and Two Lay Associate Judges

Under Section 17 LCEPA, a Labor Court adjudication panel is composed of three members: one career judge appointed by the King from among judicial officials with proven knowledge and experience in labor matters under Section 12; one lay associate judge representing employers, and one lay associate judge representing employees, both elected from candidate lists supplied by employer organizations and labor unions respectively (Section 14). Section 11 requires that the two lay sides be present in equal numbers. This tripartite composition is a defining feature of Thai labor adjudication and is intended to bring industrial-relations expertise to the bench.

Subject-Matter Jurisdiction Under Section 8 LCEPA

Section 8 of the LCEPA gives the Labor Court exclusive jurisdiction over the following five categories of dispute:

• Disputes concerning rights or duties under a contract of employment or an agreement on conditions of employment;
• Disputes concerning rights or duties under the law on labor protection, the law on labor relations, the law on state-enterprise labor relations, the law on employment service and protection of job seekers, the law on social security, or the law on workmen’s compensation;
• Cases requiring resort to court under the labor-protection, labor-relations, or state-enterprise labor-relations laws;
• Appeals against the decisions of competent officials under those laws — including, most importantly, appeals against orders of the Labor Inspector under Section 125 LPA and against orders of the Labor Relations Committee or the Minister under the LRA; and
• Cases arising from a wrongful act between an employer and an employee in connection with a labor dispute or with the performance of work under an employment contract.

The Labor Court therefore has a near-monopoly on the determination of employment-related rights. A plaintiff who mistakenly files an employment claim in the ordinary Civil Court risks dismissal for want of jurisdiction.

Two Parallel Forums: The Labor Inspector and the Labor Court

A Thai employee with a monetary grievance under the LPA has two parallel forums available: an administrative complaint to the Labor Inspector under Sections 123 to 125, or a direct civil suit in the Labor Court. These two routes are alternative — under settled practice they cannot be pursued simultaneously, and the choice of one is taken to be a waiver of the other while the chosen process is on foot.

Route One — The Labor Inspector Under Sections 123 to 125 LPA

Under Section 123 LPA, an employee whose statutory monetary entitlement under the Act has been violated may file a written complaint with the Labor Inspector of the locality where the employee works or where the employer is domiciled, in the prescribed form (the DLPW Form Khor.Ror.7). The Labor Inspector is a civil servant of the DLPW, an agency of the Ministry of Labor.

Under Section 124, on receipt of a complaint the Labor Inspector must investigate the facts and issue a written order within sixty days from the date of receipt. The investigation period may be extended by the Director-General for a further thirty days where necessary. If the Inspector finds that the employee is entitled to money under the Act, the Inspector orders the employer to pay that money to the employee (or the lawful heir of a deceased employee) within thirty days from the date the employer is notified or is deemed to have been notified of the order.

Under Section 125, any party dissatisfied with the Inspector’s order may bring the case to the Labor Court within thirty days from the date the order is known. The Section 8(4) jurisdiction of the Labor Court is what permits this de novo review. Crucially, where it is the employer that brings the appeal, the employer must first deposit with the court the full amount that the order requires it to pay. This deposit prevents the employer from using the appeal as a delaying tactic and is one of the most distinctive features of Thai labor procedure.

Failure to comply with a Labor Inspector’s order under Section 124 is a criminal offence under Section 151 LPA, punishable by imprisonment of up to one year, a fine of up to twenty thousand baht, or both.

Route Two — Filing Directly with the Labor Court

An employee is not obliged to use the Labor Inspector. Under Section 35 LCEPA, the employee (or employer in a suit by the employer) may file the plaint in writing or simply state the claim orally before a court official, who records the statement and reads it back for signature. No court fees and no witness fees are payable at any stage in the Labor Court (Section 27 LCEPA). This is a deliberate access-to-justice policy: the legislature has decided that the cost of access should not be a barrier to vindicating a labor right.

Direct filing is essential for non-monetary claims that fall outside Section 123 LPA, most importantly, claims for damages for unfair dismissal under Section 49 LCEPA, which is a Labor Court remedy and is not within the Labor Inspector’s jurisdiction. The Labor Inspector also lacks jurisdiction to award damages for breach of an employment contract that go beyond the statutory entitlements in the LPA, and lacks jurisdiction to determine claims of constructive dismissal.

Mediation Before, During, and Outside the Court: The IOM/DLPW Framework

The IOM/DLPW “Business Guidebook: How to Mediate Employment Disputes Under Thai Labour Law” (2021) sets out four distinct mediation forums available to employers and employees, and confirms that mediation is encouraged at every stage of a labor dispute. The forums are: (i) internal grievance procedures operated by the employer itself, which the LPA does not mandate but which the DLPW strongly encourages and which are required as a matter of practice for businesses certified under the Thai Labour Standard TLS 8001 and for businesses applying for the Board of Investment’s “Good Labor Practice” recognition; (ii) mediation by the Labor Inspector during the Section 124 investigation, which in practice often produces a written settlement that the Inspector then formalizes as a Section 124 order to which Section 151 LPA criminal sanctions attach; (iii) court-annexed mediation under Section 38 LCEPA (discussed below); and (iv) private mediation under the rules of the Thailand Arbitration Center (THAC) or the Thai Arbitration Institute (TAI), which is increasingly used in white-collar termination cases where confidentiality is a primary concern. The IOM guidebook explains that under the Labour Protection Act employers “are obliged to provide remediation to all workers, including migrant workers, for any human and labour rights violations reported to the labour court or labour inspector.”

Unfair Labor Practices: The Labor Relations Committee

The Labor Relations Act treats collective and union-related disputes differently. Section 121 LRA prohibits an employer from dismissing, transferring, demoting, or otherwise prejudicing an employee, employee representative, trade-union committee member, or trade-union federation committee member because of that person’s participation in a meeting, demand, negotiation, complaint, witness testimony, or other lawful exercise of labor-relations rights. Section 123 LRA prohibits comparable retaliatory acts against an employee during the pendency of a demand or agreement.

A worker who alleges an unfair labor practice under Section 121 or 123 LRA must file a complaint with the Labor Relations Committee within sixty days of the violation; the Committee has ninety days to issue an order. The Committee may order reinstatement, payment of compensation, or other remedial steps. A party aggrieved by the Committee’s order may bring the case to the Labor Court within thirty days under Section 8(4) LCEPA. Breach of Section 121 or 123 LRA is also a criminal offence under Section 158 LRA (imprisonment of up to six months, fine of up to ten thousand baht, or both).

Mediation and conciliation also play a role in collective disputes. Under the LRA, where collective bargaining negotiations fail, the parties may invoke the Conciliation Officer at the Office of Conciliation and Labor Court of the Ministry of Labor, and from there move to a Labor Dispute Arbitrator before any lawful strike or lockout. See Mediation & Conciliation and Arbitration for an overview of the firm’s ADR practice.

The Election-of-Remedies Rule

A long line of Supreme Court authority establishes that an employee must choose one route at a time: pursuing both the Labor Inspector and a direct Labor Court suit on the same monetary claim is not permitted, and a court will stay or dismiss the second-filed proceeding. The election is, however, not permanent — if the employee abandons the Labor Inspector complaint before an order is issued, the employee may then file directly in court, subject to any limitation period that has run.

Statutes of Limitation for Labor Claims

Limitation periods are easy to misjudge because the LPA itself prescribes only a few short periods, and most claims fall into the residual ten-year period of Section 193/30 of the Civil and Commercial Code. The following table summarizes the periods most often encountered in practice:

Claim	Limitation Period	Statutory Source
Severance pay under Section 118 LPA	10 years	CCC § 193/30 (residual)
Pay in lieu of notice (sin-jang taen kan bok klao luang na, also called kha tok jai) under Section 17/1 LPA	10 years	CCC § 193/30
Damages for unfair dismissal under Section 49 LCEPA	10 years	CCC § 193/30 (confirmed in Supreme Court Decision No. 4630/2565)
Special severance under Sections 120 to 122 LPA	10 years	CCC § 193/30
Wages, overtime pay, holiday pay, holiday-overtime pay (excluding severance)	2 years	CCC § 193/34(9)
Pay for accrued but untaken annual leave	2 years	CCC § 193/34(9)
Workmen’s Compensation Fund claim	180 days from the date of injury, illness, disappearance, or death	WCA § 49
Social Security Office benefit claim (most benefits)	1 year (2 years for old-age and child-allowance benefits)	SSA §§ 56, 77 jul
Appeal against Labor Inspector order under Section 125 LPA	30 days from notification	LPA § 125
Unfair labor practice complaint to Labor Relations Committee	60 days from the violation	LRA § 124 (read with §§ 121, 123)
Appeal from a Workmen’s Compensation Fund order to the Labor Court	30 days from notification	WCA § 53
Appeal from a Social Security Appeal Committee order to the Labor Court	30 days from notification	SSA § 87
Appeal of Labor Court judgment	15 days from the reading of judgment	LCEPA § 54

The classification of the claim — whether the money sought is “wages” (subject to the two-year period) or “severance/damages” (subject to the ten-year period) — is a recurring battleground. The Supreme Court has consistently treated statutory severance under Section 118 as compensation for termination, not as wages, and therefore as falling within Section 193/30, not Section 193/34(9). Practitioners should never assume that a claim is time-barred without analyzing its statutory character.

Procedure Before the Labor Court

Filing the Complaint (Free of Court Fees)

A labor case begins with a written plaint filed at the relevant Labor Court, or with an oral statement recorded by the court clerk under Section 35 LCEPA. The plaint must state the parties, the cause of action, the facts relied on, and the relief sought. Under Section 36 LCEPA, an employer or employee may authorize an employers’ association, a trade union of which the party is a member, or a competent official empowered under the labor-protection or labor-relations laws, to act as the party’s representative — a feature that has historically allowed legal aid and union counsel to litigate without a regular court-admitted attorney.

Under Section 37 LCEPA, on accepting the case, the court must fix a hearing date “without delay” and serve a summons on the defendant identifying the charge and the relief sought. In Bangkok, first hearings are typically scheduled within thirty to sixty days of filing.

Documents to Compile Before Filing

Whether the employee files with the Labor Inspector or directly in the Labor Court, the strength of the case depends to a large extent on the documents collected at the outset. A practitioner-grade checklist for an employee plaintiff includes:

• the original employment contract and every amendment, addendum, and side-letter, with any English translations;
• the work rules (khor bangkhab nai kan thamngan) of the workplace if the employer has 10 or more employees (mandatory under Section 108 LPA), together with the staff handbook and any disciplinary policy;
• monthly payslips and bank statements showing wage receipts for the entire period of employment, used to prove both wage level and length of service;
• annual income certificates issued under Section 50 bis of the Revenue Code (the “50 ทวิ” certificate) and Social Security Office contribution records;
• the termination letter, any prior written warnings, and all correspondence between the parties about the alleged misconduct or performance shortfall;
• the employee’s contemporaneous diary, emails, LINE messages, and other communications that bear on the dispute;
• contact details and short witness statements from co-workers willing to attend the Labor Court;
• for foreign employees, the work permit (Bai Anuyat Tham-ngan), the non-immigrant visa with extension stamps, the WP3 application materials filed by the employer, and any 90-day reports.

Because the Labor Court conducts an inquisitorial inquiry into the facts, and may admit evidence on its own motion under Section 45 LCEPA, the breadth of the evidentiary file matters as much as the framing of the legal claim.

Mandatory In-Court Mediation Under Section 38 LCEPA

When the parties appear at the first hearing, Section 38 LCEPA obliges the Labor Court to attempt to mediate the dispute. The provision states that the court shall conciliate the parties on the footing that “labor cases have a special character that ought to be resolved through mutual understanding so that the two sides may continue to have a relationship with one another.” Either party may request, or the court may direct, that the mediation be conducted in camera in the presence of the parties only.

If the parties reach a settlement, the agreement is reduced to writing and recorded as a compromise judgment (khamphiphaksa tam yom), which has the same enforceable effect as a contested judgment. Under Section 43 LCEPA, the court retains the power to mediate at any subsequent stage of the trial, including immediately before judgment is read.

Mediation is more than a formality. Departmental statistics published by the DLPW and the Office of the Judiciary show that a substantial proportion of cases filed each year are resolved at this stage, often within a single day. For an in-depth discussion of mediation as an alternative to contested litigation, see Mediation & Conciliation.

The Inquisitorial Trial: The Court Examines the Witnesses

If mediation fails, the court proceeds under Section 39 LCEPA to record the issues in dispute, the plaintiff’s statement, and the defendant’s answer, which are read back to the parties and signed. The court then designates which party will adduce evidence first and fixes hearing dates.

The decisive procedural feature is found in Section 45 LCEPA. The provision empowers the Labor Court “in the interest of justice in obtaining clarity on the facts of the case” to summon evidence on its own motion. Critically, the court itself questions every witness, regardless of whether the witness has been called by a party or summoned by the court; counsel may question a witness only with the leave of the court. This inquisitorial approach distinguishes Thai labor procedure from ordinary civil procedure, in which the parties lead the examination and the court intervenes only sparingly.

Under Section 46 LCEPA, the court may, where it sees fit, record only a summary of the witness’s testimony, which the witness then signs. Documentary evidence, including translations into Thai of foreign-language documents, must be submitted before the witness-examination hearing. Under Section 44 LCEPA, the court has discretion to admit any kind of evidence — including evidence that would not be admissible under ordinary civil rules — if it considers the evidence relevant and reliable.

Closing, Judgment, and Reading of the Decision

When the evidence is closed, the parties may make oral closing arguments. Under the Labor Court’s practice direction, the court is required to deliver its judgment or order within three working days from the close of evidence, although in complex cases this may be extended. The judgment is delivered in writing, states the material facts found, the issues decided, and the reasons for each decision (Section 50 LCEPA).

Section 52 LCEPA permits the Labor Court, in the interest of justice, to award relief in excess of, or different from, that prayed for in the plaint, an unusual power that gives the court flexibility to tailor remedies (for example, by awarding interest under Section 9 LPA even where not specifically requested, or by ordering reinstatement where only damages were sought).

Unfair Dismissal Under Section 49 LCEPA

The Statutory Test and the “Sufficient and Reasonable Cause” Standard

Section 49 LCEPA codifies the doctrine of “unfair dismissal” (lerk-jang mai pen tham). The provision applies whether the dismissal is technically lawful (i.e. consistent with the contract and with Section 119 LPA) or not. It empowers the Labor Court, on a finding that the dismissal is unfair, to order reinstatement at the same wage rate as at the time of dismissal, or, where the court considers that the employee and employer can no longer work together, to fix an amount of damages in lieu of reinstatement.

Whether a dismissal is “unfair” turns on whether the employer had sufficient and reasonable cause (“het somkhuan lae phiang phor”) to terminate. The Supreme Court (Labor Cases Division) has elaborated this standard in a long line of decisions. The court considers, among other matters: the seriousness of the alleged misconduct or performance failure; whether the employer followed its own disciplinary process; whether prior written warnings were issued where required by Section 119(4); the consistency of the employer’s treatment of comparable employees; and the proportionality between the conduct and the sanction of dismissal.

A dismissal that satisfies Section 119 LPA (no severance owed) may nonetheless be “unfair” for Section 49 purposes, and vice versa. The two provisions test different things: Section 119 LPA asks whether the employee’s conduct was so grave that the employer should be relieved of the severance burden, while Section 49 LCEPA asks whether the dismissal was reasonable as a matter of industrial relations.

Reinstatement or Damages: Factors the Court Weighs

Where the court orders damages in lieu of reinstatement, Section 49 requires it to take into account: (a) the age of the employee, (b) the length of service, (c) the hardship caused by dismissal, (d) the cause of dismissal, and (e) the severance pay already received by the employee. There is no statutory formula. As a working rule of thumb derived from reported decisions, the court awards approximately one month of the employee’s final salary for each completed year of service, although awards have ranged from a few months’ pay for short-service employees to upwards of ten months’ pay for long-service senior managers. Damages under Section 49 are in addition to statutory severance under Section 118 LPA and pay in lieu of notice under Section 17/1 LPA.

Constructive Dismissal: When Resignation Counts as Termination

The Supreme Court has long recognized that an employee who resigns in response to conduct by the employer that has made continued performance intolerable may sue as if dismissed. Classic fact patterns include a unilateral reduction in wages or benefits; transfer to a demeaning position or to a remote location without the employee’s consent; persistent harassment or hostile treatment by management; failure to pay wages for an extended period in breach of Section 70 LPA; and the imposition of working conditions materially different from those agreed in the contract. Where constructive dismissal is found, the employee is entitled to the same statutory severance under Section 118, the same pay in lieu of notice under Section 17/1, and the same damages for unfair dismissal under Section 49 as if the employer had formally terminated the contract. Because constructive dismissal is a de facto termination and not a statutory entitlement under the LPA, the Labor Inspector does not have jurisdiction to award the resulting severance; the employee must file directly in the Labor Court.

Recent Supreme Court Guidance

Several recent decisions illustrate the application of Section 49:

• Supreme Court Decision No. 4630/2565 (2022): The court confirmed that the statute of limitations for Section 49 damages is ten years under CCC Section 193/30, and reiterated that the touchstone is whether the employer had “sufficient and reasonable cause” to dismiss. The Labor Court below had awarded THB 375,000 in damages to a director of accounting and finance dismissed after roughly three and a half years of service at a salary of THB 226,200 per month, plus interest at 7.5% per annum from the date of filing.
• Supreme Court Decision Nos. 1757–1772/2564 (2021): A mass dismissal carried out only after the employer had exhausted alternatives — non-adjustment of salaries, removal of management, transfer of employees to foreign branches, and staff reduction — was held to be supported by sufficient and reasonable cause. The dismissals were not unfair within the meaning of Section 49.
• Supreme Court Decision No. 6729/2561 (2018): In a long-service unfair dismissal, the court awarded damages equal to approximately ten months of the employee’s final salary, having particular regard to the employee’s age and the difficulty of finding comparable re-employment.

Statutory Severance Pay Under Section 118 LPA

Statutory severance is owed whenever an employer terminates an employee otherwise than for one of the six grounds in Section 119 LPA. The schedule of entitlement was significantly enhanced by the Labor Protection Act (No. 7) B.E. 2562 (2019), which came into force on 5 May 2019 and added a new sixth bracket for employees with twenty or more years of service. The current schedule is:

Continuous Service	Severance Entitlement
120 days or more but less than 1 year	Not less than 30 days of the last-rate wages
1 year or more but less than 3 years	Not less than 90 days of the last-rate wages
3 years or more but less than 6 years	Not less than 180 days of the last-rate wages
6 years or more but less than 10 years	Not less than 240 days of the last-rate wages
10 years or more but less than 20 years	Not less than 300 days of the last-rate wages
20 years or more (introduced 2019)	Not less than 400 days of the last-rate wages

“Wages” for the purpose of Section 118 includes the regular monthly base salary plus any fixed allowances paid as part of remuneration; it does not include bonuses, irregular overtime, or one-off payments. Practitioners should examine each component of the pay package against the LPA definition of “wages” in Section 5 before computing the severance figure.

The 120-Day Threshold and Probationary Employees

Thai labor law does not recognize “probation” as a separate legal status. An employee on probation enjoys the full protection of the LPA from the first day of work, and the only threshold for the severance entitlement under Section 118 is the 120 days of continuous service in the first bracket of the schedule. An employer that dismisses a probationary employee on or before the 119th day owes no Section 118 severance, but must still give notice or pay in lieu of notice under Sections 17 and 17/1 if the dismissal is not for one of the six grounds in Section 119. A dismissal on the 120th day, by contrast, attracts 30 days’ severance, plus pay in lieu of notice, plus potential exposure under Section 49 LCEPA if the dismissal lacks sufficient and reasonable cause. The 120-day threshold has produced repeated Supreme Court litigation on the question of whether an employer that dismisses on day 119 with effect from day 120 is liable for severance; the consistent answer is yes, the calculation is made by reference to the date employment ends, not the date the notice was served.

Fixed-Term Contracts and Their Limits

Section 118 paragraph three exempts from the severance entitlement employees engaged on a genuine fixed-term contract of no more than two years for one of three statutorily defined categories of work: a project that is not the ordinary business or trade of the employer, occasional work the start and finish of which are defined, or seasonal work hired for that season. The contract must be made in writing at the outset, the start and end dates must be fixed, and the work must end on the contract end date. Where any of these conditions is missing — for example, where the contract permits early termination by either side, or where the employee is repeatedly rehired on serial fixed-term contracts performing the employer’s ordinary business — the Supreme Court has consistently held that the relationship is in substance an indefinite-term employment and the Section 118 schedule applies. Foreign employers operating in Thailand should not assume that a label of “fixed-term contract” will avoid severance exposure; the courts look at the substance of the work, not the form of the agreement.

The Six Grounds for Dismissal Without Severance (Section 119 LPA)

Under Section 119, an employer is relieved of the severance obligation only in six exhaustively listed cases:

1. Dishonesty in the performance of duty or commission of an intentional criminal offence against the employer.
2. Willfully causing damage to the employer.
3. Negligence causing serious damage to the employer.
4. Violation of work rules, regulations, or lawful and reasonable orders of the employer after a prior written warning — except in serious cases, where no warning is required. A written warning is effective for one year from the date of the underlying misconduct.
5. Absenteeism without justifiable cause for three consecutive working days, regardless of whether the absence is interrupted by a holiday.
6. Being sentenced to imprisonment by a final judgment; provided that, if the offence is one of negligence or a minor offence, the employer must show actual damage caused.

Even where one of these grounds is invoked, the employer should be aware that Section 119 only displaces the severance obligation under Section 118, it does not, by itself, preclude a successful claim of unfair dismissal under Section 49 LCEPA. The court will inquire separately into the proportionality of the dismissal. Section 119 paragraph two further requires that, if the employer intends to rely on grounds (1), (2), (3) or (5), the termination letter must state the particular ground relied on, or the employer is precluded at trial from raising it.

Pay in Lieu of Notice (Sections 17 and 17/1 LPA)

Where the employment contract has no fixed term, Section 17 LPA requires either party wishing to terminate to give written notice on or before a wage-payment date, with effect at the next wage-payment date, but no more than three months. Section 17/1, inserted by the 2019 amendment, codifies the long-standing practice that an employer terminating without the required notice must pay the employee an amount equal to the wages the employee would have earned during the missed notice period, payable on the date of dismissal. This payment is colloquially known as kha tok jai (literally “startle money”).

Section 9 LPA: 15% Annual Interest and the 15% Surcharge

Late payment of statutory sums attracts a powerful financial penalty under Section 9 LPA. If an employer fails to return a cash security, fails to pay on contract termination, or fails to pay severance, the employer must pay the employee interest at fifteen per cent per annum for the period of default. If the employer’s failure is willful and without reasonable cause and persists for more than seven days past the due date, the employer must additionally pay a fifteen-per-cent surcharge on the amount in arrears for every successive seven-day period. The Section 9 surcharge can quickly outstrip the principal in cases of obstinate non-payment, and is a powerful incentive for employers to settle once liability is reasonably clear.

Special Severance for Relocation and Technology-Driven Layoffs

The LPA prescribes additional severance entitlements in two specific situations: relocation of the place of business, and dismissals caused by changes in machinery, technology, or production processes. The current rules, as amended in 2019, are summarized below.

Situation	Statutory Source	Notice Required	Special Severance Payable
Relocation of place of business that materially affects the employee or family	LPA § 120	30 days’ written notice before relocation	Employee may terminate within 30 days and receive special severance at the Section 118 rate
Relocation without the required 30 days’ notice	LPA § 120/1	—	30 days’ wages at the last rate, in lieu of notice
Dismissal due to improvement of work unit, change in machinery or technology	LPA § 121	60 days’ written notice to the Labor Inspector and to affected employees	60 days’ wages at the last rate if notice is not given
Section 121 dismissal where the employee has more than 6 years of continuous service	LPA § 122	—	Additional special severance at 15 days’ last-rate wages per completed year over 6 years, capped at the equivalent of 360 days’ wages

The Section 121 and Section 122 entitlements are routinely overlooked by employers undertaking restructuring or automation programs. A failure to budget for them when planning a workforce reduction can convert what was intended as a cost-saving measure into a substantial litigation exposure, especially where long-service employees are involved.

Section 75 LPA: Temporary Cessation of Operations and the 75% Wage Rule

One of the most strategically important provisions for employers facing a temporary downturn, an economic crisis, a supply-chain disruption, a natural disaster falling short of force majeure, or any other event preventing normal operations is Section 75 LPA. The provision permits an employer that has “a necessity of importance which materially affects the operation of the business, such that the employer is unable to operate normally” — and which does not amount to a force majeure event — to suspend, in whole or in part, the operation of its business for a temporary period. During the suspension, the employer must pay each affected employee not less than seventy-five per cent of the wage to which the employee would have been entitled on a working day at the wage rate applicable on the latest working day, for the entire period of the suspension, not just for the days the employee would have worked. The employer must give written notice of the suspension to both the affected employees and the Labor Inspector at least three working days in advance of the suspension.

Section 75 is not a tool for cost-cutting in ordinary business conditions. The Supreme Court has consistently held that it is available only where the necessity is genuine, of major commercial importance, temporary in nature, and not the result of decisions within the employer’s ordinary control. During the COVID-19 pandemic, the DLPW issued detailed guidance confirming that the public-health-order closure of premises (cinemas, gyms, restaurants ordered closed by Provincial Communicable Disease Committees) was treated as force majeure rather than Section 75, with the consequence that the employer was relieved of the obligation to pay any wages for the period of the order, while a voluntary closure or a closure on grounds of falling demand without a public-health order remained within Section 75 and triggered the 75% obligation. This distinction generated extensive Supreme Court litigation in 2563–2566 (2020–2023). For an overview of the firm’s general business-advisory work, see Business & Commercial.

A Section 75 suspension does not end the employment relationship; the employee continues to accrue length of service, leave entitlements, and social-security coverage during the suspension. If the employer ultimately decides to terminate the employment during or after a Section 75 suspension, the full Section 118 severance schedule applies and the Section 75 payments are not counted toward it.

Working Hours, Overtime, and Holiday Pay

Wage-and-hour claims account for a substantial proportion of cases filed with the Labor Inspector and the Labor Court each year. The principal LPA provisions, as currently in force, are summarized in the table below.

Entitlement	Statutory Source	Rule
Maximum working hours	LPA § 23 (general work); Ministerial Regulations under § 22 for hazardous work	Not more than 8 hours per day or 48 hours per week. Hazardous work: not more than 7 hours per day or 42 hours per week.
Rest period during the working day	LPA § 27	At least 1 hour after not more than 5 consecutive hours of work, or two shorter periods totalling at least 1 hour.
Weekly holiday	LPA § 28	At least 1 day per week, with not more than 6 working days between holidays.
Traditional holidays	LPA § 29	At least 13 paid traditional holidays per year, fixed by the employer in advance.
Annual leave	LPA § 30	Not less than 6 working days per year after one year of continuous service; pro-rated entitlement in subsequent years may be agreed.
Sick leave	LPA § 32	As many days as actually sick; paid for up to 30 working days per year. Medical certificate may be required for 3 days or more.
Maternity leave	LPA § 41 (as amended in 2019)	Up to 98 days per pregnancy (inclusive of antenatal medical appointments under § 41(2)); 45 days paid by employer, balance paid by Social Security Fund.
Personal-business leave	LPA § 34	Not less than 3 working days per year with pay.
Overtime pay rate (weekday)	LPA § 61	1.5 times the hourly wage rate of a normal working day.
Holiday work pay (work on a weekly holiday or traditional holiday by an employee entitled to a holiday wage)	LPA § 62	An additional 1 times the hourly wage rate (i.e. double pay in total).
Holiday work pay (work on a weekly holiday by an employee not entitled to a holiday wage, such as a daily-rate worker)	LPA § 62	An additional 2 times the hourly wage rate (i.e. triple pay in total).
Holiday overtime pay	LPA § 63	3 times the hourly wage rate of a normal working day.
Wage payment frequency	LPA § 70	Not less than once a month; piece-rate work may be agreed monthly or otherwise.

Section 65 LPA exempts certain managerial roles from overtime pay and holiday-overtime pay (although the holiday-wage entitlement remains). The exemption applies to an employee “authorized to act on behalf of the employer in regard to the employment, granting of gratuities, reduction of wages, or termination of employment.” The exemption is narrowly construed: a job title alone is not enough, and the Supreme Court has rejected the exemption in cases where the employee had no real hire-and-fire authority. Section 65(2) to (9) lists additional categories of work that are exempt from overtime entitlements but entitled to receive equivalent remuneration in money. Sections 66 to 70 supplement the wage-payment regime with the rule that wages must be paid in legal tender at the workplace and that an employee’s consent is required to receive payment by bank transfer.

Wage and overtime claims are subject to the two-year limitation period of CCC Section 193/34(9). Late payment attracts the Section 9 LPA fifteen-per-cent annual interest and, where willful and unjustified for more than seven days, the additional fifteen-per-cent-per-week surcharge.

Anti-Discrimination, Sexual Harassment, and Child-Labor Protections

The LPA addresses three discrete protective regimes that frequently feature in labor litigation. Section 15 LPA requires employers to treat male and female employees equally in employment, except where the nature or conditions of the work do not permit equal treatment. Section 16 LPA prohibits sexual harassment of an employee by the employer, by any supervisor, or by any person in a position of control or supervision. A violation of Section 16 is a criminal offence under Section 147 LPA, punishable by a fine of up to twenty thousand baht. Section 144 paragraph three LPA imposes enhanced criminal penalties (imprisonment of up to one year, fine of up to two hundred thousand baht, or both) where an employer’s violation of certain protective provisions causes physical or psychological harm to the employee or results in the employee’s death.

Sections 44 to 52 LPA regulate the employment of young persons. The minimum age for employment is fifteen, and special protections apply to employees under eighteen, including a prohibition on hazardous work, a ban on night work between 22:00 and 06:00, additional rest periods, and a separate registration requirement with the Labor Inspector. Sections 49 and 50 LPA list the categories of work in which young persons may not be engaged. Section 144 paragraph four LPA imposes the harshest LPA penalties for trafficking-related child-labor violations, including imprisonment of up to two years and fines of up to four hundred thousand baht per affected child.

The Complete Schedule of Criminal Penalties on Employers (Sections 144 to 159 LPA)

A defining feature of the LPA is that it is enforced not only through the civil mechanisms of the Labor Inspector and the Labor Court, but also through a layered system of criminal penalties imposed directly on employers. Sections 144 to 159 LPA prescribe the penalties for each category of violation. The table below sets out, in consolidated form, the criminal exposure most often encountered in practice. References are to the consolidated LPA as amended through the Labour Protection Act (No. 7) B.E. 2562 (2019) and subsequent reforms. Where the underlying offence is committed by a juristic person, Section 158 LPA additionally imposes liability on the directors, managers, or any responsible person of the juristic person, unless the responsible person proves that the offence was committed without their knowledge or consent.

Violation	Penalty Provision	Maximum Imprisonment	Maximum Fine (THB)
Failing to comply with the general provisions on contract terms and conditions of employment, working hours, rest periods, weekly and traditional holidays, leave entitlements, payment of wages and overtime, payment of wages on termination (Sections 10, 22, 24, 25, 26, 37, 38, 39, 40, 42, 43, 46, 47, 48, 49, 50, 51, 61, 62, 63, 64, 67, 70, 71, 72, 76, 90 ¶1), or failing to pay special severance under Sections 120, 121 or 122	LPA § 144	6 months	100,000
Where a § 144 violation causes physical or psychological harm to an employee, or results in the employee’s death	LPA § 144 ¶2	1 year	200,000
Failing to pay wages, overtime pay, holiday pay, holiday-overtime pay, or sums equivalent to wages on suspension under § 75 (i.e. non-payment of monies due under §§ 53–55, 56, 57, 58, 59, 60, 61, 62, 63, 64, 65, 66, 67, 68, 69, 70, 71, 72, 74, 75, 77 read with § 70)	LPA § 144 ¶1 in conjunction with § 9	6 months	100,000 (plus 15% interest and 15% per-week surcharge under § 9)
Failing to comply with § 11/1 (prohibition on engaging third-party labor suppliers in a manner that has the effect of evading direct-employer obligations)	LPA § 144/1	—	100,000
Engaging in sexual harassment of an employee in breach of § 16	LPA § 147	—	20,000
Failing to render conveniences or to submit documents/records as required by a Labor Inspector or a competent official	LPA § 146	1 month	2,000
Failing to give 60 days’ written notice to the Labor Inspector before a § 121 technology-driven layoff (notification offence)	LPA § 146	1 month	2,000
Refusing to allow a Labor Inspector to enter the workplace, to inspect records, or to question employees	LPA § 148	—	20,000
Failing to keep or to maintain in the prescribed form the employee register, wage register, or other records required by §§ 112 to 115	LPA § 146	1 month	2,000
Submitting false information to the Labor Inspector or obstructing the performance of the Inspector’s duties	LPA § 150	1 month	2,000
Obstructing the duties of the Wage Committee, the Labor Welfare Committee, the Labor Inspector, or any officer; or failing to comply with the order of the Labor Inspector under § 124 within 30 days	LPA § 151	1 year	20,000
Failing to comply with an order of the Wage Committee, the Labor Welfare Committee, or any other Committee under the LPA	LPA § 152	1 month	2,000
Failure of a juristic-person employer to provide a workplace insurance policy or a self-insurance arrangement as required by §§ 121 to 122 of the WCA (relevant where the WCA cross-references LPA penalties)	LPA § 153 (read with WCA)	6 months	20,000
Failure to submit or provide an employment-conditions report (Form Khor.Ror.11) required by § 115/1, after a 15-day written warning from the Labor Inspector	LPA § 155/1	—	20,000
Failure to designate a welfare-officer for workplaces with 50 or more employees, or to constitute a labor-welfare committee under § 96, or to permit the labor-welfare committee to meet at least once every three months under § 98	LPA § 155	—	10,000
Repeat offence: any further violation of the same provision within two years of the previous offence (recidivism)	LPA § 159	Penalty doubled	Penalty doubled

Two practical consequences follow. First, a single termination handled improperly can expose the employer simultaneously to (i) the civil liability for severance, pay in lieu of notice, and damages under the LPA and LCEPA, (ii) the Section 9 interest and surcharge, and (iii) criminal liability under Sections 144 and 151 that can attach personally to the responsible director under Section 158. Second, the criminal exposure is enforced primarily through the Labor Inspector: where the Inspector has found a violation and ordered payment under Section 124, an employer’s failure to comply transforms what was a civil liability into a Section 151 criminal offence with a one-year prison maximum. Senior managers and directors of multinational employers in Thailand should treat Labor Inspector orders with the same seriousness as a court judgment.

A 2566 (2023) Supreme Court decision affirmed a suspended one-year prison sentence imposed on the managing director of a manufacturing company that failed to comply with two consecutive Labor Inspector orders for unpaid severance, even though the company itself had been wound up by the time of the criminal trial. Directors of corporate employers cannot rely on the corporate veil to insulate themselves from Section 158 LPA personal liability.

Appeals: Court of Appeal for Specialized Cases, Then the Supreme Court With Leave

Until the LCEPA was amended by Act No. 3 of B.E. 2558 (2015), an appeal from the Labor Court lay directly to the Labor Cases Division of the Supreme Court (Saalalika). Since the 2015 amendment, the route is as follows:

• First-tier appeal: Court of Appeal for Specialized Cases (San Uthon Khadi Chamnan Phisek). Under Section 54 LCEPA, an appeal lies only on points of law to the Court of Appeal for Specialized Cases, which is a specialized intermediate appellate court that includes a dedicated Labor Cases Division. The appeal must be filed in writing at the Labor Court that handed down the decision within fifteen days of the reading of the judgment or order. The Court of Appeal is bound by the facts as found by the Labor Court; if the facts found are insufficient for deciding the legal point, the Court of Appeal may remit the case to the Labor Court for further evidence.
• Second-tier appeal: Supreme Court Labor Cases Division (Saalalika Phanaek Khadi Raeng-ngan), only with leave. Under Section 57/1 LCEPA, a further appeal to the Supreme Court requires leave to appeal (kan kho anuyat dika), granted by the Supreme Court on the petition of the appellant. The Supreme Court applies a leave standard that focuses on issues of general importance, conflicting appellate decisions, and questions of statutory construction that the Court has not previously settled.

Because labor appeals are confined to points of law, the framing of issues at trial is decisive. Parties who hope to challenge a Labor Court’s factual findings will be unable to do so on appeal; the appellate courts will defer to the Labor Court’s evaluation of the evidence.

Enforcement of Labor Court Judgments

A Labor Court judgment is enforceable by execution through the Legal Execution Department (Krom Bangkhap Khadi) of the Ministry of Justice, under the writ of execution issued by the Labor Court. The execution officer may seize and auction the judgment debtor’s movable and immovable property, attach bank accounts, and garnish wages or receivables in the hands of third parties. A successful plaintiff applies for a writ of execution within ten years from the date the judgment becomes final under Section 274 of the Civil Procedure Code. Importantly, employee plaintiffs in labor cases are exempt by statute from the ten-year execution period — a measure of the legislature’s intent to protect employee judgments.

Where the judgment debtor is corporate, the successful plaintiff may apply to enforce against the company’s assets. Where the company has been liquidated or has ceased to exist, the Supreme Court has, in limited circumstances, permitted enforcement against the directors or shareholders who controlled the operation, particularly under the Civil and Commercial Code’s veil-piercing doctrines and under the Bankruptcy Act. See Bankruptcy and Debt Collection & Repossession for a fuller discussion. The Labor Protection Act establishes an Employee Welfare Fund under Sections 126 to 138; the Fund may, in cases of employer insolvency, advance certain unpaid amounts to employees and is then subrogated to the employee’s claim against the employer.

Parallel Procedures: Workmen’s Compensation Fund and Social Security Office

The Workmen’s Compensation Fund (WCF)

Where the dispute concerns injury, illness, disappearance, or death arising out of and in the course of employment, the primary remedy is not a Labor Court suit but a claim against the Workmen’s Compensation Fund administered by the Social Security Office under the Workmen’s Compensation Act B.E. 2537 (1994) (“WCA”), as amended by Act No. 2 of B.E. 2561 (2018). Employers are required to make annual contributions to the WCF, and the Fund pays compensation directly to the injured employee or to the dependants of a deceased employee. The principal heads of compensation under Sections 13 to 18 WCA are medical expenses (with caps), monthly indemnity at 70% of the monthly wage subject to a statutory cap of 14,000 baht per month, rehabilitation expenses, and a funeral allowance of 100 times the highest daily minimum wage on death. Section 18 WCA caps the maximum indemnity period at 14 years from the date of injury.

A WCF claim must be filed with the SSO within 180 days from the date of injury, illness, disappearance, or death (Section 49 WCA). The SSO investigates and issues an order; a party aggrieved may appeal to the WCF Committee within 30 days, and from the Committee’s order to the Labor Court within 30 days. The WCF route is a no-fault scheme; an employee who has been injured at work normally cannot also sue the employer in tort for the same injury, although a separate claim under Section 5 of the WCA is available where the employer’s conduct was willful or grossly negligent.

The Social Security Office (SSO)

Distinct from the WCF, the SSO administers the social-insurance benefits established by the Social Security Act B.E. 2533 (1990) for non-occupational injury and illness, maternity, invalidity, death, child allowance, old-age, and unemployment. Disputes about eligibility for these benefits are determined by the SSO, with appeals to the Social Security Appeal Committee within 30 days of notification, and onward review by the Labor Court within 30 days of the Committee’s order (Section 87 SSA). For dismissed employees, the SSO unemployment benefit pays 50% of the insured monthly salary (capped at THB 15,000 for benefit purposes) for up to 180 days if the dismissal was without misconduct, or 30% of the insured monthly salary for up to 90 days if the employee resigned voluntarily.

Special Categories of Workers and Foreign-Employee Considerations

Three categories of worker fall outside, or partially outside, the ordinary LPA regime, and require separate analysis:

• State enterprise employees, governed by the State Enterprise Labor Relations Act B.E. 2543 (2000), with adjudication by the Labor Court but procedure modified by the SELRA;
• Seafarers on Thai-flagged vessels, governed by the Maritime Labor Act B.E. 2558 (2015): see Supreme Court Decision No. 2868/2566 confirming Labor Court jurisdiction;
• Migrant workers: although holding a different immigration status, migrant workers are fully covered by the LPA. The IOM/DLPW guidebook “Business Guidebook: How to Mediate Employment Disputes Under Thai Labour Law” explains that under the Labor Protection Act employers “are obliged to provide remediation to all workers, including migrant workers, for any human and labour rights violations reported to the labour court or labour inspector.” Migrant workers may file complaints with the Labor Inspector in the same form as Thai workers and may sue in the Labor Court without paying court fees. The IOM guidebook also addresses the practical interface between LPA enforcement and the Anti-Trafficking in Persons Act B.E. 2551 (2008), which criminalizes practices such as debt bondage, document confiscation, and deceptive recruitment that frequently surface in migrant-worker disputes.

For foreign nationals employed in Thailand, two distinct legal layers apply. The substantive employment relationship is governed by the LPA and the CCC in exactly the same way as for Thai nationals: there is no distinction in severance, working-hour, or notice entitlements. The right to work, however, is governed by the Working of Aliens Emergency Decree B.E. 2560 (2017) and requires a valid work permit and a corresponding non-immigrant visa. The termination of employment of a foreign employee triggers immigration consequences within seven days; the firm regularly advises on the interaction between dismissal, work-permit cancellation, and visa status. Failure to manage the immigration timeline can lead to overstay penalties or a Thailand blacklist entry, even where the underlying labor claim is meritorious.

Practical Considerations for Employers and Employees

Successful management of a Thai labor case turns on a small number of practical points that practitioners should bear in mind before, during, and after the dispute:

• Document the disciplinary record contemporaneously. A Section 119(4) dismissal almost always stands or falls on the prior written warning. Verbal warnings are essentially worthless evidentially. The warning must identify the misconduct, refer to the relevant work rule, and be acknowledged by the employee or witnessed where the employee refuses to sign.
• State the ground of dismissal in the termination letter. Section 119 paragraph two precludes an employer from raising at trial a ground for dismissal under Section 119(1), (2), (3) or (5) that was not stated in the termination letter. A termination letter that simply states “your services are no longer required” is a near-fatal litigation error.
• Treat the first hearing as the most important hearing. The mediation under Section 38 is conducted before the same three-judge panel that will hear the case if mediation fails. Anything said at mediation will be remembered. A measured, reasonable position at mediation often produces a better outcome than a contested trial.
• Bring the witnesses to court personally. Because the court personally questions the witnesses under Section 45, the credibility of human-resources personnel and direct supervisors is decisive. Documentary evidence supports the witness; it does not substitute for the witness.
• Budget for the Section 9 LPA interest and surcharge. An employer holding back a contested severance figure for months while the case proceeds is exposed not only to the principal but to compounding fifteen-per-cent-per-week surcharges where willfulness is found.
• Mind the criminal exposure. Sections 144 and 151 LPA, read with Section 158 LPA, can result in personal liability of directors. A non-paid Labor Inspector order is not just a civil debt: it is a criminal offence.
• Plan for the immigration interface for foreign employees. The labor case and the work-permit position must be managed in tandem. See Work Permit in Thailand.
• Consider mediation outside the court. Even where the case is in the Labor Court, the parties remain free to negotiate. The firm regularly assists with structured settlements, sometimes using the Thai Arbitration Institute’s mediation rules or the THAC’s mediation rules. See Mediation & Conciliation.
• Review the employment agreement before, not after, the dispute arises. Many disputes can be averted by careful drafting of probation, performance management, and post-termination clauses. See Contract Drafting & Review.

Frequently Asked Questions on Labor Litigation in Thailand

Do I have to pay court fees to file a labor case in Thailand?

No. Under Section 27 of the Labor Court Establishment and Procedure Act B.E. 2522, filing a plaint and all subsequent proceedings in the Labor Court, including service of summons and witness fees, are exempt from court fees. This applies to both employees and employers, although in practice an employer that appeals a Labor Inspector’s order under Section 125 LPA must deposit the full amount the order requires it to pay.

How long does a labor case typically take from filing to judgment?

The Labor Court is designed to be expeditious. Section 37 LCEPA requires the court to fix the first hearing “without delay”, and most cases reach a first mediation hearing within 30 to 60 days of filing. A contested case proceeds to judgment within roughly three to eighteen months at first instance, depending on complexity and the number of witnesses. Appeals on points of law to the Court of Appeal for Specialized Cases typically take a further six to twelve months. A further appeal to the Supreme Court (where leave is granted) can add another year.

Can I be reinstated to my old job if I win an unfair-dismissal case?

Yes. Section 49 of the Labor Court Establishment Act empowers the Labor Court, on a finding of unfair dismissal, to order reinstatement at the same wage rate as at the time of dismissal. In practice, however, the court orders reinstatement only where it considers that the employee and the employer can still work together. Where the working relationship has irretrievably broken down, which is common after a contested dismissal and litigation, the court fixes damages in lieu of reinstatement, taking into account the employee’s age, length of service, hardship, the cause of dismissal, and the severance already received.

What is the difference between severance pay and damages for unfair dismissal?

They are two separate, cumulative entitlements. Statutory severance under Section 118 of the Labor Protection Act is a fixed schedule of payments based on length of service that is owed whenever an employee is dismissed otherwise than for one of the six grounds in Section 119. Damages for unfair dismissal under Section 49 of the Labor Court Establishment Act are additional and are awarded where the court finds that the dismissal, even if it satisfies Section 119, lacked sufficient and reasonable cause. A dismissed employee may receive both: the Section 118 severance plus the Section 49 damages, plus Section 17/1 pay in lieu of notice, plus, where applicable, the Section 9 LPA interest and surcharge for late payment.

How much severance pay am I entitled to under Section 118?

The current schedule, as amended in 2019, is: 30 days’ wages (120 days to under 1 year of service); 90 days (1 to under 3 years); 180 days (3 to under 6 years); 240 days (6 to under 10 years); 300 days (10 to under 20 years); and 400 days (20 years or more). “Wages” for this purpose means the regular base salary plus fixed allowances paid as part of remuneration, but does not include bonuses or irregular overtime.

What are the six grounds for dismissal without severance under Section 119?

An employer may dismiss without paying severance only where the employee has: (1) committed dishonesty in performing duties or an intentional criminal offence against the employer; (2) willfully caused damage to the employer; (3) caused serious damage through gross negligence; (4) violated work rules or lawful orders after a written warning (or, in serious cases, without warning); (5) been absent from work without justifiable cause for three consecutive working days; or (6) been sentenced to imprisonment by a final judgment. The termination letter must state the ground relied on, or the employer is precluded at trial from invoking grounds (1), (2), (3), or (5).

Is an employee on probation entitled to severance pay?

Yes, once the employee completes 120 days of continuous service. Thai labor law does not recognize “probation” as a separate legal status; the only threshold for the severance entitlement under Section 118 LPA is the 120-day mark in the first severance bracket. Dismissal on or before day 119 attracts no Section 118 severance (but still requires pay in lieu of notice under Section 17/1 if the dismissal is not for one of the Section 119 grounds), while dismissal on day 120 or later attracts the full 30-day first-bracket severance, plus pay in lieu of notice, plus potential Section 49 LCEPA exposure if the dismissal lacks sufficient and reasonable cause.

I work on a fixed-term contract. Am I entitled to severance pay at the end?

Generally yes. Section 118 paragraph three exempts only genuine fixed-term contracts of no more than two years for one of three statutorily defined categories of work: a project that is not the ordinary business or trade of the employer, occasional work the start and finish of which are defined, or seasonal work hired for that season. Where the work is part of the employer’s ordinary business, or where the contract permits early termination by either side, or where the employee is repeatedly rehired on serial fixed-term contracts, the Supreme Court has consistently treated the relationship as in substance an indefinite-term employment, and the full Section 118 schedule applies on non-renewal.

What is constructive dismissal under Thai labor law?

Thai courts recognize that an employee who resigns in response to conduct by the employer that has made continued performance intolerable is treated as if the employer had terminated the contract. Classic fact patterns include a unilateral pay cut, a punitive transfer or demotion, persistent harassment, and a sustained failure to pay wages. The employee is entitled to the same Section 118 severance, the same Section 17/1 pay in lieu of notice, and the same Section 49 LCEPA damages as if formally dismissed. Because constructive dismissal is not within the Labor Inspector’s jurisdiction, the employee must file directly in the Labor Court.

I received a Labor Inspector’s order in my favor but my employer has appealed. What happens now?

Under Section 125 LPA, an employer who brings the case to the Labor Court must first deposit with the court the full amount the order requires it to pay. The Labor Court then hears the case de novo. If the Labor Court upholds the Inspector’s order, the deposited funds are released to the employee. If the Labor Court reverses the order, the funds are returned to the employer. This deposit requirement is one of the strongest pro-employee features of the Thai labor system.

What is the statute of limitations for a severance pay claim?

Ten years, under Section 193/30 of the Civil and Commercial Code. The same ten-year period applies to claims for pay in lieu of notice under Section 17/1 LPA and to claims for damages for unfair dismissal under Section 49 LCEPA. Wage and overtime claims, by contrast, are subject to a two-year limitation period under Section 193/34(9) of the Civil and Commercial Code.

Can a foreign employee sue in the Thai Labor Court?

Yes. The Labor Protection Act applies equally to Thai and foreign employees, and the Labor Court is open to both. A foreign employee should, however, manage the immigration interface carefully: the termination of employment triggers a seven-day window for the cancellation of the work permit and may affect the validity of the non-immigrant visa. Litigation does not pause the immigration consequences. See Work Permit in Thailand and Visa in Thailand.

Is in-court mediation in a labor case mandatory?

Yes. Under Section 38 LCEPA, when the parties first appear, the Labor Court is required to attempt to mediate the case. The mediation may, on a party’s request or the court’s direction, be conducted in private in the presence of the parties only. Under Section 43, the court retains the power to mediate at any subsequent stage. A significant proportion of labor cases settle at this stage.

Can I appeal a Labor Court judgment, and to which court?

Yes, but only on points of law and only within fifteen days of the reading of the judgment, under Section 54 LCEPA. Since the 2015 amendment, the first appeal lies to the Court of Appeal for Specialized Cases (which has a dedicated Labor Cases Division). A further appeal to the Supreme Court Labor Cases Division requires leave under Section 57/1 LCEPA. The factual findings of the Labor Court are binding on the appellate courts; only legal issues may be reviewed.

What is the role of the Labor Relations Committee?

The Labor Relations Committee adjudicates complaints of unfair labor practice under Sections 121 and 123 of the Labor Relations Act B.E. 2518, for example, the dismissal of an employee in retaliation for trade-union activity. Complaints must be filed within sixty days of the alleged violation, and the Committee has ninety days to issue a binding order, which may include reinstatement and compensation. A party dissatisfied with the Committee’s order may bring the case to the Labor Court within thirty days under Section 8(4) of the Labor Court Establishment Act.

What special severance applies when the company moves location?

Under Section 120 LPA, an employer that relocates its place of business in a way that materially affects an employee or the employee’s family must give the employee at least thirty days’ written notice. An employee who does not wish to move may terminate the contract within thirty days and is entitled to special severance at the Section 118 rate. If the employer fails to give the required notice, Section 120/1 requires payment of an additional thirty days’ wages in lieu.

What special severance applies when employees are laid off because of new machinery or technology?

Under Section 121 LPA, an employer that intends to lay off employees because of an improvement to the workplace involving the introduction or change of machinery or technology must give the Labor Inspector and the affected employees at least sixty days’ written notice. If the notice is not given, the employer must pay an additional sixty days’ wages in lieu. Under Section 122 LPA, employees with more than six years of continuous service are entitled to a further special severance at the rate of fifteen days’ wages per year of service beyond six years, capped at three hundred and sixty days’ wages.

Can my employer suspend operations and reduce my pay without dismissing me?

Yes, but only under the strict conditions of Section 75 LPA. An employer facing a necessity of importance that materially affects business operations, and that does not amount to a force majeure event, may suspend operations in whole or in part for a temporary period, on at least three working days’ advance written notice to both the Labor Inspector and the affected employees. During the suspension, the employer must pay each affected employee not less than 75% of the wages to which the employee would have been entitled on a working day at the wage rate applicable on the latest working day, for the entire suspension period. The Supreme Court has held that Section 75 is not a cost-cutting tool for ordinary business conditions; the necessity must be genuine, of major commercial importance, and temporary. The employment relationship continues during the suspension; length of service, leave entitlements, and social-security coverage are unaffected.

What is the Section 9 LPA 15% interest and 15% surcharge?

Under Section 9 of the Labor Protection Act, an employer that fails to return a cash security or to pay sums due on termination, including severance pay, owes the employee interest at fifteen per cent per annum during the period of default. Where the failure is willful and without reasonable cause, and persists for more than seven days from the due date, the employer must pay an additional surcharge of fifteen per cent of the outstanding amount for every successive seven-day period. The Section 9 surcharge can quickly exceed the principal in cases of obstinate non-payment.

What criminal penalties can be imposed on an employer for breaching the Labor Protection Act?

Sections 144 to 159 LPA prescribe a layered system of criminal penalties. The general penalty for substantive violations under Section 144 is imprisonment of up to six months or a fine of up to one hundred thousand baht, or both; if the violation causes physical or psychological harm or the death of an employee, the maximum doubles to one year and two hundred thousand baht. Sexual harassment of an employee in breach of Section 16 is punishable under Section 147 with a fine of up to twenty thousand baht. Failure to comply with a Labor Inspector’s order under Section 124 is punishable under Section 151 with imprisonment of up to one year or a fine of up to twenty thousand baht, or both. Obstructing the Labor Inspector is punishable under Section 148 with a fine of up to twenty thousand baht. Failing to maintain records or submit reports attracts a fine of up to two thousand baht under Section 146. Section 158 LPA makes the directors, managers, or any responsible person of a corporate employer personally liable for offences committed by the company unless they prove the offence was committed without their knowledge or consent. Section 159 LPA doubles the penalty for recidivist offenders.

How are workplace injuries handled differently from other labor disputes?

Workplace injuries, occupational illnesses, disappearance, and death arising out of and in the course of employment are compensated primarily through the no-fault Workmen’s Compensation Fund administered by the Social Security Office under the Workmen’s Compensation Act B.E. 2537 (1994). The claim must be filed with the SSO within 180 days from the date of the incident under Section 49 WCA. The Fund pays medical expenses, monthly indemnity at 70% of the monthly wage (subject to a statutory cap), rehabilitation expenses, and a funeral allowance. Appeals lie to the WCF Committee within 30 days, and from the Committee’s order to the Labor Court within 30 days. A separate civil suit against the employer in tort is available only where the employer acted willfully or with gross negligence.

How do I claim unemployment benefits if I am dismissed?

Apply to the Social Security Office within 30 days of dismissal. An insured person dismissed without misconduct is entitled to unemployment benefit at 50% of the insured monthly salary (capped at THB 15,000 for benefit purposes) for up to 180 days per year of entitlement. An insured person who resigned voluntarily is entitled to 30% of the insured monthly salary for up to 90 days. Disputes about eligibility are reviewed by the Social Security Appeal Committee within 30 days, with onward review by the Labor Court within 30 days of the Committee’s order under Section 87 SSA.

How do I enforce a Labor Court judgment if the employer refuses to pay?

A successful plaintiff who is not paid voluntarily applies to the Labor Court for a writ of execution, which is then executed by the Legal Execution Department (Krom Bangkhap Khadi) of the Ministry of Justice. The execution officer may seize and auction the judgment debtor’s movable and immovable property, attach bank accounts, and garnish receivables. Employee plaintiffs in labor cases are exempt by statute from the ten-year execution limitation period that applies in ordinary civil cases under Section 274 of the Civil Procedure Code. Where the employer is insolvent, the Employee Welfare Fund under Sections 126 to 138 LPA may advance certain unpaid amounts to the employee and be subrogated to the employee’s claim.

Where can I find the official text of the Labor Protection Act and the Labor Court Establishment Act?

The original Labor Protection Act B.E. 2541 was published in the Royal Gazette at ratchakitcha.soc.go.th. A current consolidated text of the Labor Court Establishment and Procedure Act B.E. 2522 is published by the Ministry of Labor at mol.go.th. The Central Labor Court’s official site is lbc.coj.go.th, and the Office of the Council of State maintains a comprehensive legal database at krisdika.go.th. Supreme Court decisions are searchable at deka.supremecourt.or.th. The IOM/DLPW “Business Guidebook: How to Mediate Employment Disputes Under Thai Labour Law” (2021) is published on the IOM Asia Pacific website.

Conclusion: Acting on a Labor Dispute in Thailand

Labor litigation in Thailand is, by deliberate legislative design, accessible, fast, and protective of the employee. The exemption from court fees, the mandatory mediation, the inquisitorial procedure, and the no-deposit appeal regime all reflect a policy choice that labor rights should be vindicated without the cost and delay of ordinary civil litigation. The price of that accessibility is a procedural system that gives the Labor Court extensive discretion over the framing of issues, the conduct of the trial, the examination of witnesses, and the shape of the remedy. Parties who understand the procedure, and who present their case in the way the Labor Court expects, achieve materially better outcomes than parties who treat a labor case as just another civil suit.

The substantive exposure is no less significant. A single contested termination handled improperly can expose the employer simultaneously to severance under Section 118, pay in lieu of notice under Section 17/1, damages for unfair dismissal under Section 49 LCEPA, the Section 9 LPA fifteen-per-cent interest and fifteen-per-cent-per-week surcharge, and criminal liability under Sections 144 and 151 LPA that can attach personally to the responsible director under Section 158. For employers undertaking restructuring, automation, plant closure, or relocation, the Section 75 seventy-five-per-cent wage rule and the Section 121 and 122 special-severance entitlements must be planned for at the design stage, not after the fact.

If you are an employer planning a workforce reduction, a relocation, an automation programme, or a contested termination, or an employee considering a complaint against a current or former employer, early advice is essential. The firm advises Thai and international clients across the full range of labor matters, from disciplinary procedure design and employment-contract drafting to representation at the Labor Inspector stage and contested litigation through the Labor Court, the Court of Appeal for Specialized Cases, and the Supreme Court.
