Leave Policy in Thailand: The Employer’s Compliance Guide (2026)

Thailand’s Labor Protection Act B.E. 2541 (1998) governs employee leave entitlements and forms the legal foundation of leave policy in Thailand, which has become increasingly employee-friendly through recent amendments. For companies expanding into Thailand, understanding local labor laws is essential, particularly after Amendment No. 9 B.E. 2568 came into force on December 7, 2025, which increased maternity leave from 98 to 120 days and introduced statutory paid paternity leave.

A compliant leave policy in Thailand must account for both statutory minimums and competitive market practices. This guide breaks down every mandatory leave category, payment obligations, and the key global HR compliance considerations employers managing Thai employees from abroad need to understand.

Overview of labor laws

Thailand’s labour law framework is primarily governed by the Labour Protection Act B.E. 2541 (1998), which regulates employee rights and leave entitlements across the country. The law applies to all employers operating in Thailand, regardless of company size or the employer’s nationality, and is enforced by the Department of Labor Protection and Welfare under the Ministry of Labour. Understanding these requirements is essential for complying with broader employment laws in Thailand.

Two categories of leave entitlement matter here. Statutory leave refers to the legal minimums established under the Labor Protection Act, minimum thresholds employers cannot reduce without violating Thai law. Contractual leave refers to any enhanced leave entitlement provided through employment contracts or company policy.

A statutory employee in Thailand is entitled to these minimum protections regardless of internal company practices. Many international employers provide 10–15 days of annual leave instead of the statutory six days to remain competitive in the local talent market.

The Act has been amended several times in recent years. Labour Protection Act No. 8 B.E. 2566 (2023) introduced work-from-home provisions, while Amendment No. 9 B.E. 2568 (2025) significantly expanded parental leave rights. Employers who fail to regularly review local compliance requirements are the most likely to fall behind evolving Thai employment regulations.

Annual leave (Vacation)

Thailand’s statutory annual leave requirements are relatively modest by international standards, though many employers provide enhanced benefits to remain competitive. Annual leave entitlement in Thailand forms an important part of broader employee benefits in Thailand, especially for international employers hiring local talent.

After one full year of continuous service, employees are entitled to a minimum of six paid annual leave days. For employees with less than one year of service, leave accrues on a pro-rata basis at roughly one day for every two months worked. 

Scheduling and consent: Section 30 of the Labor Protection Act allows employers to schedule annual leave in advance without employee consent. In practice, many companies mutually agree on leave dates, but the statutory default favors employer scheduling.

Carry-over: Unused annual leave cannot legally be forfeited. Thailand’s Supreme Court has ruled that employees retain unused leave balances and their right to payment for them. This applies even if the employee does not formally request the leave of absence before year-end.

Encashment on termination: Employers must pay out all accrued and carried-over leave upon termination at the employee’s regular daily wage rate. Tracking accrued payroll liabilities accurately is, therefore, essential for compliant offboarding and payroll management.

You can compare Thailand’s statutory minimums against average paid vacation days by country when benchmarking leave policies across international teams.

Thailand does not formally recognize policies such as unlimited PTO, though employers may provide additional discretionary leave through internal policies. Likewise, optional arrangements such as voluntary time off or compensatory time off may supplement statutory leave entitlements, provided the legal minimums remain protected.

Public holidays

Thailand requires private-sector employers to observe a minimum of 13 national paid holidays each year under the Labour Protection Act, though the annual total often rises to 16 when additional royal or cultural observances are declared. Understanding Public holidays in Thailand 2026 is essential for payroll planning and statutory leave compliance.

Thai overtime rules for public holidays are strict and carry mandatory premium pay obligations when employees work on designated holidays. 

When a public holiday falls on a weekend, the following working day becomes a substitute holiday. Unlike annual leave, substitute holidays cannot be carried over into the following year.

Some employers may additionally offer optional leave arrangements such as a floating holiday through internal company policies or collective agreements.

Use this 2026 public holiday schedule when planning payroll and workforce coverage: 

Payroll teams should calculate public holiday premiums carefully, as incorrect holiday compensation remains one of the most common compliance failures identified during Thai labor inspections.

Sick leave policy

Thailand’s sick leave policy is relatively employee-friendly compared to many regional labor markets and forms an important part of broader employee benefits in Thailand.

Employees who are genuinely ill may take as many sick days as medically necessary, as Thai law does not impose a statutory cap on total sick leave duration. However, employer-paid sick leave is limited to 30 working days per year. 

Unlike maternity benefits, sick leave rules in Thailand do not provide a Social Security reimbursement mechanism for ordinary sick leave. The employer bears the full salary cost for paid sick leave obligations.

An extended illness may effectively qualify as a longer-term medical leave of absence, depending on company policy and employment contract terms.

A medical certificate becomes mandatory when an employee is absent for three or more consecutive days. For shorter absences, requesting documentation remains at the employer’s discretion.

One important distinction is that ordinary sick leave does not apply to work-related injuries or occupational illnesses, which fall under separate workplace injury protections under Thai law.

For employers managing larger teams, monitoring long-term leave usage and recurring absenteeism patterns is important for maintaining operational continuity and payroll accuracy.

Parental leave

Thailand’s parental leave framework expanded significantly following the 2025 labor law amendments and now forms an increasingly important part of broader employee benefits in Thailand.

Maternity leave

Maternity leave benefits in Thailand provide employees with 120 days of leave per pregnancy. 

The 2025 amendment also introduced an additional 15 days of infant-care leave for mothers caring for a child with a medical condition, disability, or abnormality. This leave is compensated at 50% of the employee’s regular wage.

Paternity leave

Statutory paternity leave became mandatory for private-sector employers under Amendment No. 9. Eligible employees are entitled to 15 days of fully paid paternity leave, which must generally be used within 90 days of the child’s birth.

Adoption leave

Thailand does not currently provide statutory adoption leave. Any adoption-related leave rights depend entirely on employer policy or contractual arrangements.

Job protection

Thai law prohibits employers from dismissing employees because of pregnancy. Job protection applies throughout maternity leave, and employers should ensure internal leave policies comply with evolving parental leave obligations.

As Thailand’s leave framework continues to evolve, employers managing international teams should regularly benchmark local policies against broader international benefits and compensation standards.

Other statutory leaves

Beyond annual, sick, and parental leave, employers in Thailand should also review several additional leave categories when building compliant internal workplace policies.

Bereavement / Compassionate leave

Thailand does not mandate statutory bereavement leave under the Labour Protection Act. However, many employers provide compassionate leave of absence for the death of an immediate family member through internal policies or employment contracts.

Marriage leave

Thai law does not require employers to provide marriage leave. Any paid or unpaid leave granted for weddings or civil ceremonies depends on company policy and negotiated employment terms.

Study / Exam leave

Employees may request unpaid time off for training or professional development purposes. Employers may refuse these requests under certain operational conditions permitted by Thai labor law.

Personal business leave

Thailand’s Labour Protection Act grants employees at least three days of annual personal business leave for necessary legal or administrative matters. Employers may set notice procedures, but compliant policies must formally recognize this statutory entitlement.

Voting / Jury duty

Thailand does not operate a jury duty system comparable to common law jurisdictions. Voting leave is not comprehensively regulated under the Labour Protection Act, though employers may provide flexibility through internal scheduling arrangements.

Domestic violence leave

Thailand does not currently provide a dedicated statutory domestic violence leave category. Employees facing such circumstances typically rely on annual leave, personal leave, sick leave, or employer-specific support policies.
