Hourly wage = actual monthly wage paid / number of normal working days (not more than 26) / hours per day.
| Case | Minimum rate |
|---|---|
| Overtime on a normal day | 150% |
| Overtime on the weekly rest day | 200% |
| Overtime on public holidays, Tet and paid leave days | 300% |
| Night work (22:00–06:00) within normal hours | at least 30% extra |
| Night overtime on a normal day | 200%, or 210% if daytime overtime was also worked that day |
| Night overtime on the weekly rest day | 270% |
| Night overtime on public holidays and Tet | 390% |
Night overtime = the overtime rate + 30% for night work + 20% of the daytime hourly wage of that day.
Limits: overtime may not exceed 50% of normal working hours in a day, 40 hours per month and 200 hours per year (some sectors may reach 300 hours per year).
