JustLogin automatically calculates OT4 for Malaysian clients using the Attendance module, helping your company stay compliant with Malaysia's Employment Act 1955 and the latest overtime regulations — without any manual intervention.
What is OT4?
OT4 refers to hours worked beyond 8 hours on a Public Holiday. This category ensures employees receive the correct statutory compensation for extended hours on such days, in line with Malaysian labour laws.
The table below summarises all overtime categories and when each applies:
| Overtime Type | Multiplier | When It Applies |
|---|---|---|
| OT1 | 1× | Working on an off day or rest day within normal work hours |
| OT2 | 1.5× | Working beyond normal work hours on a regular workday |
| OT3 | 2× | Working on a rest day beyond normal work hours, or working on a Public Holiday within normal work hours (up to 8 hours) |
| OT4 | 3× | Working beyond 8 hours on a Public Holiday |
How OT4 is Calculated
Normal work hours are defined as the first 8 hours of work in a day — even on a Public Holiday. When an employee works more than 8 hours on a Public Holiday, JustLogin automatically splits the shift into two segments:
- The first 8 hours are calculated as OT3 (2× rate).
- Any hours beyond 8 are automatically calculated as OT4 (3× rate).
Important: This feature currently supports overtime policy configurations that use the End Time or Standard Time methods. If your overtime policy uses a different configuration method, please contact JustLogin Support for guidance. |
Example Scenario
A staff member works 10 hours on a Public Holiday.
- The first 8 hours are calculated under OT3 at the 2× rate, covering normal work hours on a Public Holiday.
- The remaining 2 hours are automatically calculated under OT4 at the 3× rate, covering extended hours beyond the standard 8-hour threshold.
This automatic split keeps your payroll accurate and your company compliant with Malaysian labour regulations — no manual adjustments required.
