90 days from today is Tue, 17 September 2019
Where the time at which an officer is due to commence a rostered tour of duty is brought forward without due notice (less than 8 hours) so that they are required to commence duty on a day in which they have already completed their normal period of duty. The time for which they are on duty before the rostered commencement time shall be reckonable as overtime and also taken into account as part of that tour of duty. The force day commences at 7 AM.
If you are given more than 8 hours notice of the duty change then your working day merely starts at the new time. If the time you are brought on at is before 7 AM. following a period of rest days then you will be eligible to claim rest day over time (minimum 4 hours).
