You can be sure, A and C, that those that have gone to a CRM course with yours truly have received an earfull.
Take 'fatigue' for example.
I have personally done nearly as much short haul as long haul flying over the last 35 years, and can tell you for a fact that the guys I have flown with (with very few exceptions) who claimed 'fatigue' had simply not been properly rested prior to duty.
And whose fault is this?
Well, it sure as hell ain't 'management', especially when adequate hours off duty have been provided, and the crew member has not used them to the best advantage.
IF crew don't use the 'rest' hours to actually rest, they have absolutely no one else to blame but themselves...period.
