What Geordie says is correct. We used to get credit for leave. 2.5 hours per day, that was effectively getting paid for it. It stopped what is going on at the moment, where you get two weeks leave, and still get a 70 hour roster.
I'm sure the office people don't have to work weekends to make up for the days they get on leave.
May I add, that my contract says that I get 6 weeks leave a year. I can't remember the last time that happened.
However, I can't complain anymore, I took the management advise,....if you don't like it leave....the count down continues.
