How to Terminate an Employee in Thailand: A Practical Guide for Employers

For international companies operating in Thailand, ending an employment relationship is one of the most legally sensitive HR decisions you will face. Thailand's Labour Protection Act sets out clear obligations for employers, and failure to follow them can result in financial penalties, Labour Court proceedings, or both. This guide covers the key rules international employers need to understand before proceeding with any termination.

Two Types of Employment Contracts

Thai law recognises two types of employment arrangements.

1. A fixed-period contract specifies a defined start and end date, cannot exceed two years, and is reserved for specific projects, seasonal work, or tasks with a fixed completion date. When a fixed-period contract ends naturally, no severance pay is required.

2. An indefinite (permanent) contract, by contrast, applies to ongoing employment with no predetermined end date, and carries the full range of statutory protections.

Extending a fixed-period contract beyond its stated term causes it to be reclassified as an indefinite contract, which then triggers severance obligations. This is a common compliance issue for companies that repeatedly renew short-term agreements.

Termination With Cause vs Without Cause

The most important distinction in Thai labour law is whether a dismissal is with or without statutory cause. Under Section 119 of the Labour Protection Act, an employer may terminate an employee without severance pay if the reason falls into one of the following categories:

• Dishonest conduct or criminal acts against the company,

• Wilful damage to the employer, negligent acts causing serious harm,

• Repeated violation of company rules after a written warning has been issued,

• Absence from duties for three or more consecutive workdays without reasonable justification,

• Or a final court sentence to imprisonment.

Outside of these specific grounds, any dismissal is treated as termination without cause, and full severance obligations apply.

Notice Period Requirements

When terminating without cause, employers must give advance written notice. The notice must be issued at or before the next salary payment date and takes effect on the following pay date. In practice, this means a minimum of one full pay cycle, typically 30 days. Notice cannot exceed three months unless the employment contract specifies a longer period, in which case the contract terms govern.

If an employer needs to end employment immediately, they may do so by paying the employee in lieu of the notice period, calculated at the applicable daily rate for the required period.

Severance Pay Entitlements

Employees who have completed at least 120 days of service and are dismissed without cause are entitled to severance pay. The amounts, confirmed under the Labour Protection Act No. 7 (B.E. 2562, effective 5 May 2019), are as follows:

• 120 days to less than 1 year of service equals 30 days wages;

• 1 to less than 3 years equals 90 days wages;

• 3 to less than 6 years equals 180 days wages;

• 6 to less than 10 years equals 240 days wages;

• 10 to less than 20 years equals 300 days wages;

• And 20 years or more equals 400 days wages.

Severance must be paid within three days of the termination date.

Employees dismissed with statutory cause, or those who worked fewer than 120 days, are not entitled to severance pay.

The Dismissal Process

For termination without cause, Thai labour law requires the following steps.

1. Issue a written dismissal notice stating the reason and effective date.

2. Provide written advance notice at or before the salary payment date.

3. Settle all statutory payments within three days of termination: this includes final wages, severance pay, payment in lieu of notice if applicable, and compensation for unused annual leave.

4. Issue a withholding tax certificate as required by the Revenue Code.

5. Provide a job certification letter upon the employee's request, in accordance with Section 585 of the Civil and Commercial Code.

6. Notify the provident fund manager of the termination so the fund can be closed within 30 days.

Avoiding Wrongful Dismissal

Employers who violate employee rights under the Labour Protection Act face fines of between THB 5,000 and THB 200,000, and potential imprisonment of up to one year. The Labour Court can also order reinstatement or additional compensation, taking into account factors such as the employee's age, length of service, and financial hardship caused by the dismissal. Termination without proper notice, failure to pay severance, or dismissal based on alleged rule violations without prior written warnings are among the most common grounds for wrongful dismissal claims.

Managing HR Compliance in Thailand

Terminating employees correctly in Thailand requires careful documentation, timely payments, and a clear understanding of the grounds for dismissal. For international companies managing staff across the country, whether through a local entity or an Employer of Record arrangement, getting this process right from the outset protects the business from costly disputes.
