Not that I'm defending these people, because I've been jerked around too (sometimes outright and blatantly on purpose) but 80-90% of our schedulers here at Comair are brand new.

That being said, I know for a fact that the old head of scheduling (initials B.L.) hates pilots, and told his schedulers to hate pilots. During IOE class he told us he knows pilots are "out to screw scheduling to get out of work" and that it was "his job to stick it back to us." So with that mentality, we get the shaft thanks to these fine folks.
