Rat 5
You still keep getting it wrong over shift workers rosters. Its 5 on 3 off. Thats normally 0700-1900 for 2 days then 1900-0700 for 2 days, with the final shift ending at 0700 on day 5 - thats not a day off in my view.
On the other hand those that do 8 hr shifts do six on 2 off or similar.
I dont disagree your 4 on 4 off is a great idea but i also counter that you get paid a lot of dosh and would any airline manager get a nice 4 on 4 off roster?
