What does the Factories Act 1951 say about working hours in Myanmar?
The Factories Act 1951 caps regular working hours in Myanmar factories at 8 per day and 48 per week, with one mandatory weekly rest day, a 30-minute break after 5 hours of continuous work, restrictions on women's night work between 10 PM and 5 AM, and minimum-age rules for employment of minors. Overtime requires written authorisation.
What Myanmar law says
The Factories Act 1951 is Myanmar's primary working-hours statute for industrial workplaces. It applies to manufacturing, processing, and similar factories. Office staff at a factory site are typically governed by the Shops & Establishments Act, not the Factories Act. The Act sets daily and weekly hour ceilings, weekly-rest requirements, mandatory breaks, and protective provisions for women and minors.
Operationally, the township labour office inspects factories against the Act and is the first counterparty for working-time complaints. The Ministry of Labour, Immigration and Population (MoLES) sets policy and issues sectoral notifications.

| Rule | Value |
|---|---|
| Daily regular hours | 8 |
| Weekly regular hours | 48 |
| Continuous work limit | 5 hours |
| Mandatory break | 30 minutes |
| Mandatory weekly rest | 1 day (Sunday default) |
| OT cap (typical) | ~4 hrs/day, ~60 hrs/week incl. OT |
| Weekday OT rate | 2× basic |
| Weekend OT rate | 2× basic |

Edge cases
- Continuous-process operations — chemical, cement, and similar plants may run extended shifts under sectoral notifications.
- Women's night-shift exemption — certain export-oriented factories obtain pre-approval from the township labour office.
- Apprentices and trainees — included; hours count toward the 48-hour cap.
- Factory office staff — fall under the S&E Act, not the Factories Act, even on the same site.
- SEZ-registered factories — covered by the Factories Act but subject to additional SEZ regulation.
Records and inspections
The Factories Act 1951 requires the employer to keep an attendance register, OT log, leave register, and accident register. Retain ≥ 7 years (≥ 5 for OSH-only items). The township labour office conducts periodic and complaint-driven inspections; inspectors can demand the registers, payslips, women-shift authorisations, and minor-employment records on the spot.
Employer takeaway
The Factories Act 1951 caps factory work at 8 hrs/day and 48 hrs/week, with one weekly rest day, a 30-minute break after 5 continuous hours, a women's night-shift restriction (10 PM – 5 AM), and a minor-employment minimum age (14 non-hazardous, 18 hazardous). Authorise OT in writing, log it, and pay at the statutory multipliers. Retain records for 7 years; the township labour office is the inspection counterparty.
Common mistakes
- Assuming office staff at the factory site fall under the Factories Act — they don't.
- Running unauthorised women's night shifts in factories without sectoral approval.
- Missing the OT-authorisation log entirely while paying OT in cash.
- Hiring 16-year-olds for hazardous machine operation — the threshold is 18.
