Singapore Employment Act: A Plain English Guide

Who is covered?

The Singapore Employment Act applies to most employees who work under a contract of service. It applies whether the worker is Singaporean, Permanent Resident, or a foreign employee on an S Pass or Work Permit. It applies whether the contract is in writing or verbal, whether the worker is full-time, part-time, on a fixed-term contract, or on a daily rate.

What it does not directly cover is the self-employed and independent contractors — although the Platform Workers Act 2024 has now extended specific protections to platform-based gig workers (CPF, work injury compensation, representation). That is a separate piece of legislation and we cover it in a dedicated guide.

Within the Act itself, there is an important distinction between general coverage and Part IV, the section that deals specifically with rest days, hours of work, overtime and other day-to-day operational rules. Part IV only applies to:

• Workmen earning a basic monthly salary of up to S$4,500
• Non-workmen (most office-based or service staff) earning a basic monthly salary of up to S$2,600

For shift-based businesses, this threshold matters a lot. Most floor staff in F&B, retail and hospitality will fall under Part IV, which means OT rules, rest day rules and working-hour limits apply. A duty manager earning S$3,200 may not be entitled to OT under the Act, even if they regularly do extra hours.

Working hours

Under Part IV, the standard working hours are capped at:

• 8 hours per day if working a 6-day week
• 9 hours per day if working a 5-day week
• 44 hours per week in total

An employee cannot be required to work more than 12 hours in a single day (including OT), except in specific circumstances such as actual emergencies, work that is essential to the life of the community, or work that is essential to defence or national security.

A shift cannot exceed 12 hours without those exceptional grounds, and even then MOM expects a clear justification. For an F&B outlet running a long peak Friday or a hotel facing an unexpected staffing gap, this is a real constraint — and a clear reason to plan rosters so that 12 hours is rarely reached.

Overtime rules

Overtime is work done beyond the contractual or standard working hours. Under the Employment Act, for staff covered by Part IV, OT is paid at 1.5 times the hourly basic rate of pay.

The hourly basic rate is calculated as:

Maximum OT under Part IV is 72 hours per month. Going beyond that is a breach of the Act and MOM can — and does — investigate.

Importantly, only Part IV staff are entitled to OT pay as a legal right. If your duty manager earns S$3,000 a month, they are not covered by Part IV and have no statutory right to OT pay. That does not stop you offering OT pay as part of their contract; many businesses do, especially in tight labour markets. It just means the rate and rules are between you and the employee, not dictated by the Act.

Public holidays

Singapore has 11 gazetted public holidays: New Year's Day, Chinese New Year (2 days), Good Friday, Hari Raya Puasa, Labour Day, Hari Raya Haji, National Day, Deepavali, Christmas Day, and one more depending on the calendar.

Every employee covered by the Employment Act is entitled to those 11 paid public holidays. For shift workers, the rules around working on a PH are where most disputes arise:

• If the employee works on a public holiday, the employer must either pay an extra day's pay at the basic rate of pay, or grant a day off in lieu, on top of the gross pay for that day.
• If the public holiday falls on a rest day, the next working day becomes a paid holiday in lieu.
• If the public holiday falls on a non-working day (for staff on a 5-day week), the employee is entitled to a day off in lieu or one extra day's pay.

Rest days and Sunday work

Every Part IV employee is entitled to at least one rest day per week. The rest day is a continuous 30-hour period and is unpaid (since it is not a working day). The rest day is typically Sunday but can be any day of the week — agree it with the employee.

If an employee works on a rest day at the employer's request, the pay multiplier depends on hours worked:

• Up to half the daily working hours: 0.5 day's pay
• More than half, up to a full day's hours: 1 day's pay
• Beyond normal daily working hours: 1 day's pay plus OT at 1.5x for the additional hours

If the employee chooses to work on a rest day (i.e. requests it), the multiplier is lower (0.5 day's pay for up to half the daily hours, full day's pay beyond that). The distinction between "at employer's request" and "at employee's request" matters financially.

Annual leave and medical leave

Annual leave under the Act starts at 7 days a year after the first year of service, rising by one day per additional year up to a cap of 14 days. Many Singapore employers offer more than the statutory minimum, particularly for full-time roles — 14-18 days is common in F&B and retail.

Medical leave is split between outpatient and hospitalisation:

• Up to 14 days of paid outpatient sick leave per year
• Up to 60 days of paid hospitalisation leave per year (inclusive of the 14 outpatient days)

Both require a medical certificate from a Singapore-registered doctor, dentist, or a doctor at an approved hospital. We cover the detail in our annual leave and medical leave guide.

MOM enforcement

The Ministry of Manpower enforces the Employment Act. MOM officers can inspect workplaces, request payroll and timesheet records, and prosecute breaches.

The most common reasons employers run into trouble:

• OT calculations done wrong — either at the wrong rate, or beyond the 72-hour cap.
• Inadequate records — MOM requires employers to keep employment records for at least two years for current employees, and one year after an employee leaves.
• Public holiday pay miscalculated — particularly when shift workers' hourly rate or gross pay is unclear.
• Rest day violations — running shift workers six days in a row without giving them their statutory rest day.

Penalties range from administrative composition fines (typical for first-time, minor breaches) to court prosecution for serious or repeated violations. The reputational impact of a MOM enforcement notice can also be material for businesses that rely on hiring through portals like MyCareersFuture.

Practical steps for shift-based employers

1. Map each role against Part IV. Note whether each employee is covered (workman up to S$4,500, non-workman up to S$2,600) or not. This determines OT and rest-day entitlement.
2. Keep clear records of hours. Every shift should have a recorded start and end time. Reconstructing timesheets after MOM asks is not a defensible position.
3. Build OT into your pay calculation, automatically. Manual OT calculation is where most errors creep in. The 1.5x multiplier, the part-day OT for rest days, the gross-pay treatment of PH — they compound. Software that knows the Singapore rules saves your team hours and reduces risk.
4. Watch the 72-hour OT cap. A few staff doing heavy OT during peak weeks is easy to miss until cumulative hours quietly exceed the cap.
5. Document leave fairly. Annual leave applications, medical certificates, and lieu days should all be on file. For shift workers, this is doubly important because cover scheduling depends on knowing who is genuinely unavailable.
