200 days a year including holidays and training days.
Broken down to 50 days per 3 months.
The roster is optimised to give 6 days on, 5 days off within the constraints of the above. Roster is issued mid month for the next month. Duty per 6 days is max of 55 hours.
Depending on the fleet and position, it's rare to work more than 18 days. More typical is 16 days.
We can request SDOs (special days off) before the roster's issued. 6 per year.
Day 1 and Day 6 are the start and finish days, you do not commute on your days off unless it's an exceptional case.
