My guess is that it starts with the training guys who possibly do not instill good habits and/or do not follow through with enforcing these good habits.
Nope, your way wrong on that one, well, were I am anyway.
It does get a tad tiring being worn down day in and day out by management that constantly erode your "cast-in-stone" contract, no salary increase, no bonus, increased flying time, less lay-over time, yet we are still required to operate as professionally as always. And we do, its just that our "attitude" changes..................plenty.
I'll try be more pleasant next time we fly together.....................
