A Thai company was prosecuted for multiple labor violations including unpaid overtime and unsafe working conditions. Learn about employer obligations and employee protections.
This case study is based on anonymized real-world situations and is presented for educational purposes only.
The Situation
A medium-sized manufacturing company in Rayong was reported to the Department of Labour Protection and Welfare by a group of 15 employees (including 3 Myanmar nationals with valid work permits). The complaints included unpaid overtime for the past 6 months, failure to provide social security contributions, and unsafe working conditions (lack of protective equipment in a chemical handling area).
Legal Issues Involved
Unpaid overtime (Labour Protection Act B.E. 2541 (1998), Section 61)
Failure to contribute to Social Security Fund (Social Security Act B.E. 2533 (1990))
Unsafe working conditions (Occupational Safety, Health and Environment Act B.E. 2554 (2011))
Equal treatment of foreign workers with valid work permits
What Happened (Process)
- 1
Collective complaint filed by 15 employees at provincial Labour Office
- 2
Labour inspector conducted unannounced workplace inspection within 14 days
- 3
Inspection confirmed: unpaid overtime records, missing social security payments, safety violations
- 4
Employer ordered to remedy violations within 30 days
- 5
Employer partially complied but disputed overtime calculations
- 6
Labour Court proceedings initiated by employees with legal aid assistance
- 7
Court ordered full payment of back overtime plus 15% interest
- 8
Separate criminal prosecution for safety violations resulted in fine
Outcome
The employer was ordered to pay THB 1.8 million in back overtime and benefits to all 15 employees, plus THB 450,000 in social security arrears. A criminal fine of THB 200,000 was imposed for safety violations. Two company directors received suspended prison sentences.
Key Lessons
Thai labour law applies equally to Thai and foreign employees with valid work permits.
Employers must maintain accurate records of working hours and overtime payments.
Labour inspections can be triggered by employee complaints and are conducted without advance notice.
Social security contributions are mandatory — failure to pay is a criminal offence.
Collective complaints by multiple employees strengthen the case significantly.
