You have two airlines with different industrial profiles and different bosses. I would guess the common factor driving the discontent is that the Head Honcho for each really doesn't like his pilots.
The discontent is a human reaction against being disliked by someone who has control over your life. You need that person for your bread and butter but don't like to accept they pull your strings. I liken it to a school culture. Good headmaster equals good school. Bad Head and you have social problems. The children still learn to read but enjoy resentment and years later air their feelings on Freinds Reunited.
Both these airlines show a rather Victorian attitude to staff and therefore get pulled apart. There is no easy (or perhaps there is!) answer to the strife. Money and productivity solutions rarely make a difference.
