Unfair Dismissal in Thailand: Challenging at the Labour Courts

What is unfair dismissal under Thai law?

The Labour Protection Act (LPA), the main law governing labor rights in Thailand, strictly regulates the conditions for contract termination. A dismissal is considered unfair when it is executed without just cause, without following legal procedures, or without payment of due compensation.

• Lack of a valid reason provided in writing
• Failure to comply with the legal notice period (or non-payment of severance pay)
• Discriminatory dismissal (pregnancy, union activity, illness...)
• Failure to pay mandatory end-of-contract compensation

💡 Good to know

In Thailand, the employer must always provide written notice of the reason for dismissal. A verbal dismissal or one without a written reason significantly weakens the employer's position before the Labour Court.

Steps to contest before the Labour Court

1. Attempt conciliation with the Department of Labour (DoL)

Before bringing your case to the Labour Court, it is advisable — though not mandatory — to file a complaint with the Department of Labour Protection and Welfare (DLPW). A mediator will try to reach an amicable agreement. This step is often quick (7 to 30 days) and free of charge.

2. File a claim with the appropriate Labour Court

If no amicable agreement is reached, you will file your claim with the Labour Court in the geographical area where you worked. In Bangkok, this is the Central Labour Court; in the provinces, regional Labour Courts are competent.

• Critical deadline: 30 days from the date of dismissal to take action
• Filing requirements: application form + employment contract + evidence
• The process is relatively accessible: no lawyer is required, but strongly recommended

3. Prepare your evidence file

A solid file is crucial. Gather:

• Your employment contract (in Thai or bilingual)
• The dismissal letter (or proof of its absence)
• Pay slips from the last 6 months
• Written communications, emails, professional messaging
• Witness statements from colleagues if possible
• Proof of payment (or non-payment) of legal compensations

⚠️ Warning

The 30-day deadline is strict. After this period, your claim will be inadmissible. Act without delay, even if amicable negotiations are ongoing.

What compensation can you obtain?

If unfair dismissal is recognized, the Labour Court may order:

• Reinstatement in the position (rarely granted in practice)
• Legal severance pay: from 30 to 400 days of salary based on length of service
• Unpaid wages and unfulfilled notice period
• Additional damages if harm is demonstrated

✅ Practical advice

Have all your documents translated into Thai as soon as possible. The Labour Court primarily operates in the Thai language. A bilingual local lawyer or a certified interpreter is a significant asset for effectively defending your rights.

The role of your embassy and additional resources

Your embassy or consulate in your home country can guide you to registered lawyers in Thailand, but it does not intervene directly in local labor disputes. For prompt support, a local lawyer specializing in Thai labor law remains the most effective recourse.
