What Myanmar law says
Overtime in Myanmar is not automatically mandatory. Two conditions must be met for an employer to require it:
- OT is authorised in writing or by established practice consistent with the contract.
- OT stays within the statutory caps — typically 4 hrs/day and 60 hrs/week including overtime under the Factories Act 1951.
Where both conditions are satisfied, an employee cannot generally refuse. Refusal is permitted if OT would breach health, safety, or another statute — for example, women on factory night shifts (10 PM to 5 AM) under the Factories Act, or minors with stricter hour limits.
When OT can be required vs. refused
| Scenario | Can employer require? | Notes |
|---|---|---|
| Authorised, within cap | Yes | Refusal can be a disciplinary issue |
| Beyond 4 hrs/day cap | No | Refusal protected; employer faces penalty |
| Women on night shift in factory | No | Restricted under Factories Act |
| Minors | No | Stricter hour limits apply |
| Health / safety risk | No | OSH Law 2019 applies |
| Pregnant or post-partum | Limited | Maternity protections apply |
Documentation requirements
- Written OT authorisation (per shift or rolling consent).
- Attendance log capturing in/out and OT hours.
- Payslip with OT itemised at 2× / 3× multipliers.
- Record retention: at least 7 years.
Edge cases
- Compensatory off — allowed only with employee written consent.
- Senior managers — sometimes contractually exempt from OT pay; OT cap still applies for safety.
- Emergency / breakdown — limited extension allowed under Factories Act, with reporting.
- Repeated refusal — without lawful ground, can be cause for warning, not automatic dismissal.
- Garment CMP factories — peak-season OT must still respect the 4 hrs/day cap.
- Voluntary OT below cap — must still be paid at premium rates (see OT rate).
Employer takeaway
OT is enforceable when authorised in writing and within statutory caps (typically 4 hrs/day, 60 hrs/week). Employees may refuse if it breaches statute, safety, or restricted-category protections (women night shift, minors, pregnant workers). Pay at 2× / 3× multipliers, itemise on payslips by the 7th of the following month, and retain authorisation logs for 7 years.
Common payroll mistakes
- Treating "expected to work late" as authorisation — write it down.
- Pushing past the 4 hrs/day cap during peak season and exposing the employer to penalty.
- Disciplining an employee who refused on safety grounds — protected refusal.
- Forgetting that women on factory night shift cannot be required to do OT after 10 PM.
- Calling unpaid hours "voluntary" — voluntary OT is still OT and must be paid at premium (see OT calculation).
