Thailand Termination and Severance: Rules, Notice, and Costs (2026)

Thailand's Labor Protection Act B.E. 2541 sets severance pay from 30 to 400 days of wages based on tenure. The 2019 amendment added a new tier: 400 days for employees with 20+ years of service. Dismissal for misconduct requires no severance. Advance notice follows the wage payment cycle. Thailand has one of the most generous severance scales in ASEAN for long-tenured employees.

What Severance Pay Rates Apply in Thailand?

Severance is calculated on the last rate of wages. 'Wages' includes basic salary plus any fixed regular payments but excludes overtime, irregular bonuses, and reimbursements. For an employee earning THB 50,000/month with 12 years of service: 300 days × (THB 50,000 ÷ 30) = THB 500,000 ($14,100). Employees with less than 120 days of service receive no severance.

What Notice Period Is Required for Termination in Thailand?

Thailand does not have a fixed statutory notice period for termination. Section 17 of the LPA requires advance notice on or before a wage payment date, effective on the next wage payment date. For monthly-paid employees, this means approximately one pay cycle (up to 1 month). The employer can pay wages in lieu of notice.

Example: if wages are paid on the last day of the month, and the employer gives notice on March 15, the termination is effective on April 30. If notice is given on March 31, termination is effective on April 30. The notice must be at least one wage payment cycle. Employment contracts can specify longer notice periods.

What Are the Grounds for Termination Without Severance?

Section 119 of the LPA lists six grounds for dismissal without severance or notice. Dishonest performance of duties or intentional commission of a criminal offense against the employer. Intentionally causing damage to the employer. Violating work rules and receiving a written warning (except for serious offenses). Absence without justification for 3 consecutive working days. Imprisonment by a final court judgment (except for petty offenses or negligence). Gross negligence causing serious damage to the employer.

For misconduct dismissal (except serious offenses), the employer must have issued a prior written warning. The warning must describe the offense and state that repetition will result in termination. Verbal warnings do not count. The written warning must be specific: generic warnings are insufficient. If the employer cannot prove the warning was given, severance is owed.

What Is Special Severance Pay in Thailand?

Beyond standard severance, the LPA provides additional compensation in specific scenarios. Relocation: if the employer relocates the workplace and the employee does not wish to relocate, the employee receives standard severance. Business changes: if the employer modifies operations, organization, or transfers, and the employee is affected, special compensation of 15 days wages per year (minimum 15 days) applies in addition to severance.

Retrenchment: when the employer terminates due to machinery installation, technology changes, or organizational restructuring, the employer must give 60 days advance notice or pay 60 days special wages in addition to severance. These additional payments stack on top of the standard severance scale.

What Is Unfair Dismissal in Thailand?

Thailand's Labor Court hears unfair dismissal claims. Employees can file within the statute of limitations (10 years for breach of contract claims). The Labor Court can order reinstatement or compensation. In practice, most cases settle with enhanced severance packages. The employee can also file a complaint with the Labor Inspector for unpaid wages or severance.

Common unfair dismissal scenarios: termination without valid cause, failure to follow contractual or work rule procedures, discriminatory termination, and constructive dismissal (employer makes conditions intolerable). The burden of proof is on the employer to demonstrate just cause for dismissal. Companies should document all performance issues and disciplinary actions thoroughly.

Can an employer terminate during probation without severance?

If the probation period is 119 days or less, no severance is required (below the 120-day threshold). If probation exceeds 120 days, severance of 30 days wages applies. Most Thai employers set probation at exactly 119 days for this reason. The employer must still provide advance notice per the wage payment cycle during probation.

Is there a retirement age in Thailand?

The LPA does not set a mandatory retirement age. Many companies set retirement at 55 or 60 in their work rules. If the employer terminates due to retirement, full severance applies. If retirement is at 60 or older as specified in work rules, and the employee has 20+ years of service, the employee receives 400 days wages severance.

What is the cost of wrongful termination in Thailand?

Wrongful termination typically results in: standard severance pay + compensation for unfair dismissal (negotiated or court-ordered). Courts consider the employee's length of service, salary, difficulty in finding new employment, and the employer's conduct. Total awards commonly reach 6-18 months salary inclusive of severance. Legal fees add THB 100,000-500,000+.

Must the employer state the reason for termination?

Yes. Section 17/1 of the LPA (2019 amendment) requires the employer to specify the reason for termination in writing at the time of dismissal. If the employer does not state the reason, the employer cannot later assert that reason in a labor dispute. This provision prevents employers from fabricating post-hoc justifications.

Can fixed-term contracts avoid severance in Thailand?

Yes, if the fixed-term contract is for genuinely seasonal or project-based work not exceeding 2 years. The contract must specify the start date, end date, and the nature of the temporary work. If these conditions are not met, the contract is deemed indefinite-term and severance applies upon expiration. Rolling fixed-term contracts for ongoing work do not avoid severance obligations.
