Kinda funny listening to this thread...and I'm certain it will get more colorful in the days/weeks to come.
Your representative group is only what you and your fellow members make of it. Inhouse, outhouse, ALPA, Teamsters, APA, IPA, SWAPA ...CBA. None of them matter if your members (and the leadership) aren't engaged and working together. Volunteer members spend enough time fighting their respective companies...makes the job even more difficult when you spend energies fighting your own members. Keeping in mind you can only give '100%', so any part of that which is misdirected...well, you get the jest.
Changing affiliations really doesn't fix whatever problem you have.
I recognize the issue for Atlas is an attempt to outwit the decision/award that is not in their favor. For the rest of their problems (some have been aired thru this forum)...well, they remain either way.
