Overtime rounding floors in hourly workforces
Daily rounding that looks trivial on one timesheet becomes a systematic underpayment across a factory roster.
A rule that rounds each overtime block down to the next fifteen minutes is easy to miss in a configuration workbook. It is often inherited from a clocking system, then confirmed in the payroll suite as “minutes precision: 15.”
On a single timesheet the difference is small. Across three hundred hourly people, six days a week, the unpaid remainder is no longer small, and it is directional — it almost never rounds in the employee’s favour.
When we test exception rules we do not start with the payslip. We start with the clock record, apply the Employment Act ordinary rate of pay, then apply the suite’s rounding, then the payslip. The middle step is the one operations teams skip because the suite does not print it.
If your workforce is monthly-rated and rarely works OT, this note will not matter. If you run shifts in Selangor’s industrial belt, it is the first rule we ask to see.
