We have a lot of provisions that are not friendly to pilots, and heavily favor management. If you commute, the problems are exemplified... if you do what @Lord Ratner does, the issues are mitigated significantly.
Off hand: No double dipping, no reassignment premium pay except for actual time flown outside original sequence block in, Recovery Obligation for a sequence that has a Misconnect, Illegality, or Cancellation that extends to 0159 the day after for domestic, or +30 hours from block in for international, only 150% premium, premium is seniority based (great for those at the top), trips blocked for IOE rather than being bought off (can still be bought off, but less common), significant disagreements with Management on Notification rules, negligible profit sharing, a near incompetent IT team, Loss of License (LTD) monthly pay capped at 60% or $8k, whatever is less, 60 hours of sick time a year, no timeline to settle grievances so there are 100+ of them pending, and the company enjoys "Fly and Grieve" afforded to them by the RLA, etc.
All of these are largely Scheduling issues that can be fixed contractually. The other half of AAs problem are pilots who have seen the worst of the industry, and are 1) permanently jaded about life 2) constantly believe they should be made whole and are mad that it hasn't happened yet 3) refuse to learn how to manipulate our contract to their advantage 4) blame everyone else for not fixing their personal pet peeve (x6000 other pilots with their own personal pet peeve.)
Despite all the above, I still enjoy working here. If you live in a mega hub, you can make a lot of money by working very little comparatively. If a pilot gets wrapped on the Union forums or the Facebook groups... well, misery loves company... and there's several hundred vocal pilots who won't be happy until you agree with them on how awful everything is.
edit: still leaps and bounds better than AD, and I have more free time then I know what to do with. pilots having an entire second business is a real thing here.
