How OT Pay Works in Thailand: Labour Law Guide
Overtime (OT) pay is an employee right under the Thai Labour Protection Act — know the formula.
OT Rates
Base hourly rate = daily wage ÷ 8
| Type | Rate |
|---|---|
| Weekday OT (after hours) | 1.5× |
| Holiday work (regular hours) | 2× |
| Holiday OT | 3× |
Calculation Example
Daily wage 500 THB, 3 hours of weekday OT:
- Base hourly: 500 ÷ 8 = 62.50 THB
- OT rate: 62.50 × 1.5 = 93.75 THB/hour
- Total OT: 93.75 × 3 = 281.25 THB
Key Points
- OT requires employee consent
- Certain weekday OT exceeding 3 hrs/day must be paid at 3×
- Employers who don’t pay OT can be reported
