What Myanmar law says
Myanmar factories are governed by the Factories Act 1951, which sets the standard working week at 48 hours. The act applies to manufacturing, processing, and similar industrial workplaces. Office staff at a factory site (HR, finance, admin) are usually treated under the Shops & Establishments Act at 44 hours instead — even when their workplace is on the factory campus.
The 48-hour week is most often run as 6 days × 8 hours, with Sunday as the rest day. Some factories operate a 5.5-day schedule (full Saturday morning, half-day afternoon) or a 6-day rotational schedule that aligns to a continuous-process licence.
Factory working-hour limits
| Element | Factories Act 1951 | Notes |
|---|---|---|
| Standard week | 48 hours | Across 6 days typical |
| Daily regular hours | 8 | Excludes break |
| Continuous work limit | 5 hours | Then 30-min break required |
| Lunch break | 30 min | Unpaid |
| Weekly rest | 1 day | Sunday default |
| Total w/ OT | ~60 hrs/week | ~4 hrs/day OT cap |
Factory-specific edge cases
- Continuous process — chemical, cement, and similar plants may run 12-hour shifts with adjusted rest under sector notifications; the 48-hour weekly average should hold.
- Women on night shifts — restricted between 10 PM and 5 AM in factories under the Factories Act, except for pre-approved sectors.
- Minors (14–18) — daily caps tighter than 8 hours; no night work; hazardous tasks reserved for 18+.
- Apprentices and trainees — covered by the Factories Act when working at the site; hours count toward the 48-hour cap.
- Office staff on factory campus — apply the 44-hour S&E rules; never the 48-hour Factories Act standard.
Records and inspections
Factory employers must keep an attendance/hours register, OT authorisation log, leave register, and accident register, retained for ≥ 7 years (≥ 5 years for OSH-only records). The township labour office inspects factories more frequently than offices and can demand the registers, OT logs, and payslips during an inspection. Failure to maintain records is a standalone offence even if hours are otherwise compliant.
Employer takeaway
Run Myanmar factories on a 48-hour week under the Factories Act 1951, 8 hours per day, with a 30-minute break after 5 continuous hours and one weekly rest day. Office staff at the same site follow the 44-hour S&E standard. Keep attendance, OT, and leave registers for 7 years. The township labour office is the inspection counterparty; first violations typically draw a remediation order plus a fine.
Common mistakes
- Using the 48-hour factory cap for office staff at the same site (they should be on 44).
- Running 7-day weeks during peak season without paying weekly-off compensation.
- Letting daily continuous work exceed 5 hours without a 30-minute break.
- Permitting women in factories to work past 10 PM without the sectoral approval the Factories Act requires.
