Not really germane here, but lets follow your concept for a minute... Looking at recent history of pilot groups who've left ALPA.
How about USAPA?
(Notwithstanding the absolute abject failure they have been at enhancing the careers and bank accounts of their membership.)
How about FPA?
(Oh wait, they were an massively ineffective failure too!)
The pilots realized the effectiveness of ALPA and impotence of being "independent" and have been very successful since they re-affiliated.
Name a pilot group that has had better long term
success by leaving ALPA. Please, I'd love have solid examples. (.....You do realize "independent union" is an oxymoron, right?)
Who really cares "how long it takes", I care about results, the infrastructure to achieve results and influence outcomes. "Independent union"
hasn't been and won't be the solution.
