I thought that you had to be in a union at a union airline (which is almost all of them, I'd guess). Is this a choice at some places? I just figured that it was inevitable. Get the job, join the union, and off you go.
If I wanted to live a life of politics and infighting.......I'd stay in the Marine Corps.
I thought that the scabs were only around during a strike, and then promptly dumped as part of terms of the eventual reconciliation between the management and the union. Do some of them get to stay on (and get abused by the members).
Naaaaaa .... you don't HAVE to join the Union, even in "closed-shop" states, but why not?? You're gonna have to pay dues anyway, in most states ... so you might as well come onboard and get the "bennies" that your dues money is going toward. ESPECIALLY NOW w/ a Democrat in the White House ...

If you don't want to be an active Union-guy ... don't. BUT: remember, if you fly for a "real" airline, your salary is probably what it is as a direct result of the sacrifices of ALPA guys who came before you ...
SCABs are not only "new" guys who cross a picket line ... they are frequently (usually in the airlines ??) guys who you've sat next to and flown w/ in the past ... but who now put their OWN well-being ahead of the rest of the Brotherhood when the shit hits the fan ...
So when the strike is over ... they stay on as regular pilot employees ... but their life, as they "know it", is over for all intents & purposes.
HEY!! We're NOT the fuckin' Teamsters ... we're professionals. BUT: we do not tolerate those w/ NO HONOR in our midst ... would YOU do anything less in the Corps ... ???
