Normal hours
Contractual hours are capped at 44 a week (or up to 9 a day for a five-day week). An employee cannot be required to work more than 12 hours in a day, except in the limited situations MOM lists.
Overtime pay
Overtime is paid at not less than 1.5 times the hourly basic rate. The hourly basic rate for a monthly-rated employee is (12 × monthly basic) ÷ (52 × 44). Overtime must be paid within 14 days of the end of the salary period.
The 72-hour cap
Overtime is capped at 72 hours a month, unless MOM has granted the company an exemption.
Rest day
Every Part IV employee is entitled to one rest day a week, unpaid, and the longest stretch between two rest days may not exceed 12 days.
How Cohumi handles it
- The roster is checked against 12 h/day, 44 h/week, a weekly rest day, 12 days between rest days and 72 OT h/month as you plan — and Cohumi tells you the date someone will cross the line.
- Overtime pay is computed at the person's rate; an agreed rate can be set per person, and Cohumi flags any rate below 1.5× for Part IV staff.
- Each rule links to the MOM page it comes from.
Questions
Does a shift allowance replace overtime pay?
Only if it is at least what the overtime would have been. Cohumi checks a rostered-hours allowance against the 1.5× rule and tells you.
