They also dumped almost every station they did ground handling at, almost at once, with minimal notice in most cases. That was around the time I left, but afterwards, Skywest lowered the pay of the SFO employees below airport minimum wage(despite employees complaining it was illegal), and then got in trouble with the city of San Francisco for it, because that is illegal. Which they knew but did anyway. "But we have to give part time employees health care and we can't afford it!".
But of course, they'd never screw the pilots. Ever. They promise.
