Yup - must agree, it doesn't feel fair to have to work your 90 hours in a condensed period in order to avoid crewing shortages, but the other guys are correct - everyone I know in similarly paying jobs come back to 2 weeks work, and spend half their holiday on their phone keeping up to date with what's going on in the office.
However, I think we all agree that flying is a special case thanks to the unique conditions and demand placed on staff, so I certainly hope people don't think they have it easy by comparison - everyone else gets Christmas, New Year's etc off!
Part time is a bit of a shafting too, if you're random roster I generally see companies offering more days off but still getting full time hours from part timers - surely it should be based upon an assumed days-per-week, hours-per-day calculation!
Then again, there are many 'should be's in this industry!!!!
