Overview of Thailand's Labour Law Framework

Thailand’s employment laws are governed primarily by the Labour Protection Act B.E. 2541 (1998), along with the Civil and Commercial Code, the Labour Relations Act, and various ministerial regulations. These laws apply to nearly all private-sector employers and employees in Thailand.

The main goals of the laws include:

  • Ensuring fair treatment of employees

  • Establishing minimum working standards

  • Providing a structured process for employment disputes and termination

Employment Contracts in Thailand

While Thai law allows verbal agreements, written employment contracts are strongly recommended—especially for foreign-owned companies. A bilingual contract (Thai and English) is best practice, and in case of dispute, the Thai version will prevail in Thai courts.

Key provisions to include in employment contracts:

  • Job title and responsibilities

  • Work location and hours

  • Salary and payment method

  • Overtime policy and compensation

  • Leave entitlements (annual, sick, maternity, etc.)

  • Termination clause and notice period

  • Confidentiality, non-compete, and probationary terms

💡 Pro tip: Clearly define the employment relationship to avoid misclassification and potential legal claims.

Working Hours, Wages & Overtime

Thai law limits standard working hours to 8 hours per day or 48 hours per week for most jobs. For hazardous work, the maximum is 7 hours per day and 42 hours per week.

Minimum Wage

Thailand sets a regional minimum wage that is reviewed periodically. Employers must ensure full compliance with the minimum wage laws and issue detailed payslips each month.

Overtime

Employees working beyond normal hours are entitled to overtime pay, often at 150%–300% of their regular wage, depending on the time and day (e.g., weekends or public holidays).

Leave and Employee Benefits

Thai employees are entitled to the following types of leave:

  • Annual leave: Minimum 6 days per year (after one year of service)

  • Sick leave: Up to 30 paid days per year

  • Maternity leave: 98 days (45 paid by employer)

  • Personal leave: Often granted at the company’s discretion

  • Public holidays: At least 13 days per year

Employers must also register employees with Thailand’s Social Security Fund, which covers medical care, unemployment, and retirement contributions.

Termination & Severance Pay

Notice Period

Unless terminated with cause, employers must provide at least one pay period’s notice or payment in lieu of notice.

Severance Pay

Employees terminated without cause are entitled to severance pay based on their length of service:

Service Duration Severance Pay

120 days – <1 year 30 days’ wages

1–3 years 90 days’ wages

3–6 years 180 days’ wages

6–10 years 240 days’ wages

10–20 years 300 days’ wages

More than 20 years 400 days’ wages

Unused annual leave must also be paid out upon termination.

❗ Employers that fail to follow proper termination procedures may be subject to wrongful dismissal claims, fines, or court-ordered compensation.

Unfair Dismissal & Labour Disputes

Employees who believe they’ve been unfairly terminated may file a complaint with the Labour Court, which has broad discretion to order reinstatement or award monetary compensation.

To reduce risk, employers should:

  • Issue written warnings and maintain proper records

  • Use mutual separation agreements where appropriate

  • Seek legal advice before terminating long-serving employees or those in sensitive roles
