For employees that have normal working hours, overtime usually means any time worked beyond these hours.
Normal working hours are the hours fixed by an employment contract.
Employers don’t have to pay workers for overtime. However, employees’ average pay for the total hours worked mustn’t fall below the National Minimum Wage.
An employee’s employment contract will usually include details of any overtime pay rates and how they’re worked out.
