Is overtime capped per month in Myanmar?
Myanmar law caps overtime principally on a daily and weekly basis, not a fixed monthly ceiling. Daily OT is typically capped at around 4 hours and weekly total hours at around 60 under the Factories Act 1951 and S&E Act. Sectoral notifications and international buyer codes often add a monthly OT cap (commonly 36 to 60 hours).
What Myanmar law says
Myanmar's primary OT caps are daily and weekly, not monthly. Daily OT is typically limited to around 4 hours, and total weekly hours including OT cap at around 60 under the Factories Act 1951 and Shops & Establishments Act. Whether an employee can work, for example, 60 hours of OT in a 4-week month is therefore implicitly capped by the daily and weekly limits, not by a separate monthly figure.
That said, three external constraints often apply a monthly cap in practice:
- Sectoral notifications issued by MoLES for specific industries.
- International buyer codes (Better Work, brand-specific compliance programs) which commonly set 36–60 hours/month.
- Internal company policy aligning to buyer codes for export-oriented operations.
OT-cap landscape
| Scope | Cap | Source |
|---|---|---|
| Daily OT | ~4 hrs | Factories Act 1951 / S&E Act |
| Total weekly hours (incl. OT) | ~60 | Factories Act 1951 / S&E Act |
| Monthly OT (statutory) | None fixed by general statute | — |
| Monthly OT (sector notification) | Sector-specific, often 36–60 hrs | MoLES sector notification |
| Monthly OT (buyer code) | Commonly 36–60 hrs | Buyer code (e.g., Better Work) |
Edge cases
- Garment / footwear export — buyer codes typically apply 60-hour total weekly cap and ~36-hour monthly OT cap; align internal policy.
- BPO / contact centres — fewer external constraints; daily and weekly caps drive the monthly limit.
- Continuous-process plants — sector notifications govern.
- Hospital staff — sector-specific scheduling rules.
- Multi-month peak — sustained high-OT months should be flagged for OSH risk-assessment review.
Records and inspections
OT authorisation logs and attendance registers should support a monthly OT-total view per employee. The township labour office looks at running totals during inspection. Buyer audits in export sectors specifically demand monthly OT trend data, often for the prior 3–12 months. Retain ≥ 7 years.
Employer takeaway
Myanmar's general statute caps OT daily (~4 hrs) and weekly (~60 hrs total), not by a fixed monthly figure. In practice, sector notifications and international buyer codes commonly impose a 36–60 hour monthly OT cap. Track monthly OT per employee, align internal policy to the strictest applicable rule, and retain logs for 7 years. Sustained high-OT months should trigger an OSH risk-assessment review.
Common mistakes
- Citing a non-existent statutory monthly OT cap and missing the daily/weekly caps that actually bind.
- Tracking only weekly OT and missing the monthly trend that buyer audits scrutinise.
- Failing to align internal policy with the stricter buyer code in export sectors.
- Letting sustained high-OT months continue without an OSH review.
