SARcastic, the reason I mentioned the guy falling asleep was as a warning. He was obviously burning the candle at both ends and in the end has no one to blame but himself. The point of it really is that if someone is working days off and flying on the maximum limits of the duty/flying scheme then they are likely to be more fatigued than someone who isn't and could end up going the same way. Remember, management won't defend you or say thanks.
As regards to the 'bust limits - report them' comment then you've already covered it. Are they thinking about the safety of their passengers? No. So what do you do? Sit back and ignore it or do something about it? Is it more professional to do nothing? If the profession is ever going to be taken seriously then we have to move away from these cowboy 'oh I'll just readjust my start time on the duty form' attitudes.
I agree with the 'do it through BALPA' point but I mentioned that before. Incidently, I believe that BALPA has stopped Bristows from removing a local allowance from the staff - so there's one small success.
