Overtime is the payment given to an officer for extra attendance outside of the standard working week. It is only payable after the completion of the required working hours for the grade in question. In addition, employers should be satisfied that the amount or nature of the work to be done makes overtime unavoidable. Attendance on Saturdays, Sundays and public holidays should be kept to a minimum. Every effort should be made to avoid a situation where staff attend for very short periods only.
