You can claim overtime if you are:
A non-workman earning up to $2,600.
A workman earning up to $4,500.
The overtime rate payable for non-workmen is capped at the salary level of $2,600, or an hourly rate of $13.60.
For overtime work, your employer must pay you at least 1.5 times the hourly basic rate of pay. Payment must be made within 14 days after the last day of the salary period.
An employee can only work up to 72 overtime hours in a month.
Employers can apply for an exemption if they require employees to work more than the 72 hours of overtime in a month.
The employer has to make sure that no worker works more than 10 days without a rest day of 24 hours. Therefore, if the worker is asked to work on weekly holiday, he should have full holiday on one of three days immediately or after the normal day of holiday.
