Yes, and no. In either case it's a cop out.
Some try with varying opinions, motives, and degrees of information will try to lead. Many (most?) have no idea where they're going. ATA pilots were mislead by their MEC's many times. We had four MEC Chairs over 5 years. All were accused of incompetence and corruption at some point. Even when they're honest, they must follow the dictums and $$$ from ALPA national. Without their blessing, nothing happens. I've sat in on quite a few teleconferences with the group and it's leadership. I've listened and read the "Mustache Magazine" and find nothing of value. ALPA national has no desire to fight for anything except its own existence, but even then they'll sell out. When I was at TSA back in the '90s, same thing, under guidance from national. Frankly, ATAlpa knew our '02 contract was unsustainable. They believed we were going to be sold, so they didn't care.
You can also blame the system under which airlines and unions operate. Both sides are happy with this arrangement! (I'm speaking of the RLA in case you don't know.) Neither side functions in reality. They lie to themselves, their stockholders, and their constituents, when they have no idea what's going to happen. They soon figure it out in "Chapter 7."
I've been working with some former Aloha guys, and they tell of similar stories.
I'm curious, just what should ALPA have done? I've watched first hand the Aloha situation, from what I have seen is management ran the airline into the ground and they shut down. Had it not been for ALPA, the AQ guys would have worked for a lot less while the company went under and probably not salvaged any of their retirement.
