Many multinational companies are familiar with the concept of “time off in lieu” (TOIL), under which employees receive compensatory time off instead of overtime pay for additional hours worked. While TOIL is common in many jurisdictions, employers in Thailand should be cautious, as Thai labor law does not expressly recognize TOIL as a substitute for statutory overtime-related compensation. Under the Labor Protection Act B.E. 2541 (1998) (LPA), employees who work overtime or perform work on holidays are generally entitled to statutory overtime, holiday, or holiday overtime compensation, including: Overtime Pay: 1.5 times the employee’s normal wage rate for work performed beyond normal working hours on a regular working day. Holiday Pay: 1 or 2 times the employee’s normal wage rate for work performed during normal working hours on a holiday, depending on category of employee. Holiday Overtime Pay: 3 times the employee’s normal wage rate for overtime work performed on a holiday. Importantly, the LPA does not contain any provision expressly permitting employers to substitute overtime-related compensation with compensatory leave, as such compensation is treated as a payment obligation rather than additional time off. Why TOIL Can Be Risky in Thailand Thai labor law is protective in nature, and statutory entitlements to overtime, holiday, and holiday overtime pay are generally regarded as minimum employee rights. As a result, these rights cannot be waived, even with the employee’s consent. Therefore, an employer who grants TOIL instead of paying statutory overtime-related compensation may still be exposed to claims for unpaid amounts, notwithstanding that compensatory leave has already been provided. Thai courts have affirmed this principle, holding that employers remain liable for statutory payments for work performed beyond normal working hours even where substitute time off has been granted. Are There Any Exceptions? Certain categories of employees are exempt from overtime-related compensation,

On August 25, 2026, Thailand’s cabinet approved in principle a draft amendment that would extend mandatory social security coverage to three categories of workers currently excluded from Thailand’s compulsory social security system. The amendment, proposed by the Ministry of Labour, would modify the Royal Decree Prescribing Businesses and Employees Excluded from the Social Security Act B.E. 2560 (2017). Newly Covered Workers The cabinet-approved proposal would remove the exclusions for the following three categories of employees, bringing them within Thailand’s mandatory social security system: Workers in seasonal cultivation (pho pluk), forestry (pa mai), and livestock (liang sat) businesses that do not employ workers year-round and whose operations do not include other types of business activities. Notably, fishery (pramong) workers were excluded from this amendment following objections raised at a Social Security Board meeting on April 30, 2025, because employers and employees in the fishery sector can already agree to opt into social security coverage under fishery labor laws. Domestic workers and other employees of individual employers where the work performed is not part of a business operation (e.g., housekeepers, gardeners, drivers). This group has actively demanded inclusion in the social security system. Workers employed in street-stall businesses operating fixed street stalls (kan kha phaeng loi). The rationale for including street-stall workers is that their employers have fixed, identifiable places of business that can be inspected. Accordingly, workers engaged in itinerant street hawking (kan kha re) remain excluded. The expanded coverage would apply to both Thai and foreign employees who possess valid identity documents and work permits, including migrant workers who have been granted special permission to work in Thailand. The Social Security Act B.E. 2533 (1990) does not restrict social security registration based on nationality, allowing these workers to register as insured persons under section 33.

Thailand’s cabinet has approved two draft amendments aimed at improving labor-related judicial proceedings. The proposed amendments to the Act on the Establishment of Labor Courts and Labor Case Procedure B.E. 2522 (1979) and the Act on Procedures for Human Trafficking Cases B.E. 2559 (2016) are intended to make the process more efficient, appropriate, and fair. Key elements of these proposed amendments are outlined below. Expansion of Labor Court Jurisdiction Under the current framework, labor courts generally hear labor disputes, while criminal offenses under labor laws are handled separately. Matters involving both labor and criminal issues may therefore require the parties to pursue proceedings before different courts. To address this, the proposed amendments would expand the jurisdiction of labor courts to cover certain criminal offenses under labor laws. The government states that the change is intended to allow related issues to be heard by judges with expertise in labor law and to reduce the need for parallel proceedings. The proposed amendments also set out the following rules for cases involving multiple offenses. Where a single act gives rise to multiple offenses and at least one of those offenses falls within the jurisdiction of the labor court, the labor court may hear the related offenses as part of the same case. Where multiple connected acts give rise to different offenses, the labor court may hear the matters together or transfer part of the case to the appropriate court, taking into account convenience and the interests of justice. Criminal Offenses Covered The proposed amendments would extend labor court jurisdiction to criminal offenses under 11 labor-related laws, including laws concerning: Home workers protection Labor protection Labor protection in fisheries work Employment and job-seeker protection Management of foreign workers Social security Occupational safety, health, and working environment Compensation Maritime labor State enterprise labor relations

Thailand has introduced a new regulatory framework that may expose foreign nationals who violate the Foreign Business Act (FBA) to deportation. The Regulation of the Office of the Prime Minister on Deportation B.E. 2569 was published in the Government Gazette on August 27, 2026. The regulation establishes an administrative process for referring foreign nationals for deportation where this is deemed necessary in the interests of public order or public morality. It does not create new substantive deportation powers, but it expressly identifies unlawful business conduct under the FBA—including nominee arrangements—as grounds for referral. Grounds for Deportation Referral The regulation sets out five grounds that may give rise to a referral to the relevant authorities: Unlawful entry into, or unlawful stay in, Thailand in violation of immigration laws. Unlawful employment or engagement in work in violation of laws governing the employment of foreign nationals. Carrying on business in violation of the FBA, including through the use of nominee arrangements. Forging official documents or using forged official documents. Committing an offense punishable by imprisonment of five years or more. The framework takes a broad approach, extending not only to the perpetrators of these acts but also to those who facilitate, instigate, or otherwise support such acts. Deportation Risk Following a Criminal Judgment Where a foreign national has committed any of the above offenses and has fully served the sentence imposed pursuant to a final judgment, the interior minister has the power to order deportation. This power also applies where a court has issued a final judgment sentencing a foreign national to imprisonment but has suspended the execution of the sentence, or has imposed a fine. A deportation order may also specify a period during which the foreign national is prohibited from reentering Thailand. FBA Noncompliance: Broader Consequences Noncompliance with the FBA—including
