To answer Mr. Bloggs
Re Reserve, credit it back to 1 for 5 which will give a disincentive to roster long reserve periods and IMHO would be acceptable.
Re stacking the rosters during a month with leave, make the credit 84 divided by 30 which equals 2.8 hours per day on L, that's fair isn't it? How did they come up with 2 hours anyway?
Surely the more credits we get the more pay (or less work) we get and the more pilots the company need to meet the task, which is good for everyone, except maybe management!
