How is leave calculated for part-time employees in Myanmar?

What Myanmar law says

Part-time employees in Myanmar receive pro-rated statutory leave based on their contracted working pattern. The Leave and Holidays Act sets full-time entitlements (10 annual, 6 casual, 30 sick, 14 weeks maternity, ~21 public holidays); the contract pro-rates these in proportion to the part-timer's contracted days per week or hours per week. Both the Factories Act 1951 for factory workers and the Shops and Establishments Act for office, retail, and hospitality staff treat part-time leave consistently.

The pro-rata formula is straightforward: if a full-time employee works 5 days a week and gets 10 days of annual leave, a part-timer working 3 days a week gets 10 × (3 ÷ 5) = 6 days annual leave. Sick and casual leave use the same logic.

Pro-rata leave entitlement

Pay calculation for part-time leave

• Determine the part-timer's "monthly salary equivalent". If paid hourly: hourly rate × contracted hours × 4.33 weeks/month. If paid per-day: daily rate × contracted days × 4.33 weeks/month.
• Apply the same /30 daily-rate formula. Daily rate = monthly equivalent ÷ 30.
• Multiply by leave days taken. Daily rate × leave days = leave pay.
• Encashment at exit. Use the same (monthly equivalent ÷ 30) × unused-days formula.

Public holidays and part-time workers

A part-time employee receives paid public-holiday treatment only for holidays that fall on their contracted working days. If a public holiday falls on a non-contracted day, the part-timer is not paid extra for that holiday but also does not lose anything — they were not scheduled to work.

Example. A part-timer contracted to work Monday, Wednesday, Friday gets paid public holidays for any Mon/Wed/Fri gazetted day. A Tuesday public holiday is not part of their pay calculation.

Worked example — part-time leave at exit

Part-timer paid MMK 200,000/month equivalent (3 days/week, MMK 50,000/day), 18 months service, resigns with 4 unused annual-leave days:

Note: the per-shift daily rate (MMK 50,000) differs from the /30 monthly-equivalent daily rate (MMK 6,667). Use the /30 convention for leave pay; the per-shift rate is for shift payment, not leave pay. Codify which rate applies to leave in the contract to avoid disputes.

Edge cases and exceptions

• Probationary part-timers. Same eligibility gates — annual at 12 months, sick at 6 months.
• Variable-hours part-timers. Use the average over a reference period (typically the past 13 weeks).
• Job-share arrangements. Each job-share employee gets pro-rated leave based on their own contracted days.
• Daily-wage part-timers. Continuous-engagement criteria still apply; pay is the daily wage × pro-rated leave days.
• SSB. Contributions on actual earnings under the MMK 300,000/month cap; eligibility for benefits unchanged.
• Maternity / paternity. Event-driven duration is the same (14 weeks / ~15 days), but pay base is the part-time salary.
• Foreign part-time workers. Same pro-rata treatment.
• Factory vs office. Same pro-rata treatment under both sub-statutes.

Frequently asked questions

Does this entitlement apply to employees on fixed-term contracts?

Yes. Fixed-term contract employees in Myanmar receive the same statutory leave floor as permanent employees once they meet the relevant service-tenure thresholds. The Leave and Holidays Act, the Factories Act 1951, and the Shops and Establishments Act do not distinguish between fixed-term and indefinite contracts for leave purposes — eligibility is set by months of continuous service. Contract expiry is not termination, so unused annual-leave balance is encashed at the end of the contract using (monthly salary ÷ 30) × unused-days. See the bucket E pages on fixed-term contracts for the contract-side rules.

How does this interact with payroll and SSB?

All paid leave is treated as ordinary salary income for Myanmar payroll purposes. PIT is withheld through PAYE on every payslip that includes leave pay. SSB contributions (2% employee + 3% employer, capped on a wage base of MMK 300,000/month) continue during paid leave because the employee is still earning wages. SSB contributions pause only during unpaid leave. Encashment of accrued annual leave at exit is part of taxable salary for PIT but practitioners differ on SSB treatment of the lump sum — confirm with the township SSB office on filing.

What records does the township labour office expect?

Inspectors typically request the leave register for the past 12 months, medical certificates for sick leave over 3 days, maternity / paternity SSB filings, final settlement worksheets for recent leavers, and the public-holiday gazette for the current year. Records must be retained for at least 7 years under both the Factories Act 1951 and the Shops and Establishments Act. Keeping a clean per-employee leave file with tagged entries makes inspections quick and defensible. Digital records from a payroll system are acceptable provided they can be printed on demand.

Common leave-law mistakes

• Granting full-time leave to part-timers. The statutory floor is pro-rata, not flat.
• Paying public holidays for non-contracted days. Pay only when the holiday falls on a contracted day.
• Using per-shift rate for leave pay. Use the monthly equivalent ÷ 30 convention unless the contract explicitly says otherwise.
• Forgetting SSB on part-time earnings. Contributions on actual earnings under the cap.
• Not codifying the working pattern. Without a clear contract, pro-rata calculations become disputed.
