Two major issues:
1. Many of the servces that ALPA provides are so expensive that no independant union could afford them, such as legal council, negotiating council, medical services, HIMS, etc. Many large independent unions such as the APA contract these services out from ALPA for a hefty fee.
2. I'm not ure about other regionals, but Endeavor's JBCA-TA has language in the contract that says if Endeavor pilots dump ALPA, then Endeavor loses their flying.
#2 is the most fudged up thing that I've ever heard in my life... a trade "union" included language in their membership's contract that says "if you get rid of us then you lose everything". Doesn't sit right in my tummy.
THose things being said, I am all for a RALPH.
