Myanmar Factories Act Overtime Rules Explained (2026 Guide)
What the Factories Act 1951 says about working hours, overtime, weekly rest, and penalties for non-compliance. Plain-English guide for factory HR and operations.
Under the Factories Act 1951, factory workers in Myanmar work a maximum of 8 hours per day and 44 hours per week, with at least one full day of weekly rest (typically Sunday). Any hours worked beyond the daily or weekly limit are overtime, paid at 2× the ordinary hourly rate. Overtime must not exceed 12 hours per week except in special circumstances. Work on a weekly rest day or gazetted public holiday triggers additional premium pay or compensatory day off.
What qualifies as a "factory" under the Act?
The Factories Act 1951 applies to premises where 10 or more workers are employed AND manufacturing processes are carried on with or without power. This includes:
- Garment and textile factories
- Food and beverage manufacturing
- Automotive assembly and parts
- Metal and plastic fabrication
- Printing and packaging
- Chemical and pharmaceutical production
Shops, offices, and service businesses are NOT factories — they are covered by the Shops and Establishments Law 2016 (SEL 2016), which has slightly different hours (48/week vs 44/week).
Working hours under the Factories Act
| Item | Limit |
|---|---|
| Maximum daily hours | 8 hours |
| Maximum weekly hours | 44 hours |
| Minimum weekly rest | 1 full day (typically Sunday) |
| Meal/rest break | At least 30 minutes after 5 continuous hours |
| Maximum continuous work without break | 5 hours |
Important: The 44-hour week is typically scheduled as 8 hours × 5 days + 4 hours on Saturday, OR 8 hours × 5.5 days. The half-day Saturday is very common in Myanmar factories.
The overtime rules
Daily overtime
Any work beyond 8 hours on a working day is overtime. OT rate: 2× ordinary hourly rate.
Example: A worker earns MMK 400,000/month. Ordinary hourly rate = 400,000 ÷ (26 × 8) = MMK 1,923/hr. Daily OT rate = 1,923 × 2 = MMK 3,846/hour.
Weekly overtime
If total weekly hours exceed 44, the excess is overtime regardless of daily distribution. Same 2× rate applies.
Weekly rest day work
If a worker works on their weekly rest day (usually Sunday), the employer must:
- Pay 2× ordinary rate for those hours, AND/OR
- Give a compensatory day off within 3 working days
The exact combination depends on the workplace's Standing Order and industry practice. Most Myanmar factories pay 2× and give a comp-off.
Gazetted public holiday work
⚠️ FLAGGED — The multiplier for gazetted public holiday work has conflicting sources:
- Some sources read the Factories Act as 2× (with pay in lieu allowed)
- Some interpretations cite 2.5×
- Some sector collective agreements go to 3×
QHRM's default advice: Apply at least 2× and consult your Standing Order or sector agreement before publishing a policy. Most factories in Yangon and Mandalay now apply 2× plus a compensatory day off in practice.
The 12-hour weekly overtime cap
The Factories Act limits total overtime to approximately 12 hours per week. This prevents factories from scheduling excessive OT that erodes worker health.
Practical implication: Plan your production schedule so no one worker is on OT more than 12 hours in any given week. If a worker exceeds this, both the worker and the factory are exposed — the factory to inspection, the worker to health risk.
Some sources cite higher caps (up to 20 hours) for specific circumstances, but the 12-hour rule is the safe default. Do not schedule beyond 12 hours OT/week without legal sign-off.
Meal break, rest, and shift length rules
- Meal break: At least 30 minutes after 5 continuous hours of work.
- Split shifts: Allowed but total span (shift start to end) should not exceed 10 hours for day workers or 10.5 hours including break.
- Night work: Allowed but with additional considerations for women and juvenile workers (see Factories Act sections on restricted work).
- Women workers: Additional protections — historically restricted night work, though interpretation has evolved. [VERIFY] with current Ministry of Labour guidance.
Overtime worked example — 2-shift Myanmar garment factory
Scenario: Day shift 8am–5pm, 1 hour lunch break. Sunday is weekly rest. Sewing operator earns MMK 350,000/month.
- Ordinary hours: 8/day × 6 days = 48 hrs (includes Sat 4 hr half-day)
- But Factories Act max is 44/week → so the last 4 hours of the week are OT
- Ordinary hourly rate: 350,000 ÷ (26 × 8) = MMK 1,683/hr
- Weekly OT (4 hrs): 4 × 1,683 × 2 = MMK 13,464
Now Sunday work (compensatory day off given):
- 8 hours × 1,683 × 2 = MMK 26,928
Week total additional: MMK 40,392 on top of base salary.
Note: If the factory uses the SEL 2016 48-hr week basis, the weekly OT portion above would be zero. Confirm which law applies to your establishment.
Enforcement and penalties
Violations of the Factories Act are enforced by Factory and General Labour Laws Inspection Department (FGLLID). Penalties include:
- Warnings and requirements to remediate (most common)
- Fines for repeat violations
- Facility shutdown orders in severe cases (unsafe conditions, no OT payment, no rest day)
- Criminal liability for factory managers in worst cases
Inspectors can arrive unannounced. They typically review:
- Attendance logs
- Overtime payment records
- Standing Order filing
- First aid and safety provisions
- Women and juvenile worker records
Standing Order — the factory-specific rulebook
Every factory must file a Standing Order with the Labour Exchange Office. The Standing Order sets out:
- Shift schedules
- Overtime policy (rates, caps)
- Weekly rest day
- Leave policy
- Disciplinary procedures
- Grievance mechanism
The Standing Order is enforceable like the Factories Act at that specific facility. If your Standing Order says OT is 2.5× on public holidays, that is the binding rate.
7 common factory OT mistakes
- Applying SEL (48 hrs) instead of Factories Act (44 hrs). Offices are 48, factories are 44.
- Not paying for half-hour meal break. Meal break is unpaid but not counted in working hours.
- Scheduling >12 hrs OT/week regularly. Technically capped, and labor inspection catches this.
- No compensatory day off for Sunday work. Some factories pay 2× and skip the comp-off — check your Standing Order.
- Using monthly salary ÷ 30 for hourly rate. Most Myanmar practice is ÷ 26 working days (factories) or ÷ 22 (offices).
- Silence on public holiday rate in the contract. If silent, the default interpretation applies — which may be less favorable than you expect.
- Manual OT calculation. Spreadsheet errors are the #1 source of factory payroll disputes.
How QHRM handles Factories Act OT
- Shift patterns (1/2/3 shift, relief, split) built-in
- 44-hour weekly threshold applied automatically
- Daily and weekly OT computed per worker per shift
- Sunday / weekly rest OT flagged with optional comp-off tracking
- Gazetted public holiday flagged for premium pay
- 12-hour OT cap alerts HR when any worker approaches the limit
- Multi-site rollup for group-level OT cost dashboards

Frequently asked questions
Q: Does the Factories Act apply to a factory with fewer than 10 workers? No — the Act triggers at 10 workers. For smaller premises, SEL 2016 or general employment law applies. But most labor principles (OT premium, rest day, meal break) are still best practice.
Q: Can we pay OT as a fixed monthly allowance instead of calculating per hour? Not advisable. Any "OT allowance" that doesn't reflect actual OT worked can be challenged and ordered to be topped up. Calculate actual OT.
Q: What if workers request to work >12 hrs OT for extra income? Document the consent, but the cap is there for health reasons. Consistent breach will be flagged in inspection. Better solution: hire more workers if demand is sustained.
Q: Are supervisors and managers exempt from OT rules? Managerial and supervisory roles are often treated as exempt in practice, but the Factories Act does not automatically exempt them. Confirm treatment for each role in your Standing Order.
