You know its very interesting here and what I have noticed is that the rushing and the pressure is actually done by the pilots. Not the roster. If you just do your own thing at your normal pace and schedule be damned, then they will adjust the schedule to allow more time and thus reduce the delays.
"Pilot Pushing" is by and large self induced. We are all a highly motivated goal oriented lot. Many of us came out of the military. Hence the letter that Cecil Ewiell wrote to the pilots of American Airlines after Little Rock as he was leaving the position of Chief Pilot.
It was called : There is no Mission.
The thrust of it was exactly what the title says. This is not a war, lives will not be lost if we don't fly. However, pressing on no matter what WILL cost lives.
It was a good letter and the only time in my career that I have heard such a thing from management. (I have worked at 7 airlines) Usually a pilot is doing a rug dance because a gate agent complained he was slow to push back or something.
