Fact.....
3 Union drives, all failed some by more than others, but still no Union or any prospect, so yeah, no "critical mass". To "fight" for improvements there has to be a mechanism. Wishing, whilst easy is not very effective. There are 2 options at this point, #1-accept it for what it is, and live with it, or #2-leave and get what you desire elsewhere.
The irony is in an industry where no one wants to rock the boat, even if they escape the regionals and get to a major, that attitude will just move with them. Kinda sad really.
