Wow. Seems serious to me.
Decades ago I worked as a flight attendant (for another airline). I can pretty much grasp some of the details that may appear as mere ciphers to those not acquainted with in-flight personnel contract language. So I realize the above links show union interpretation. But even allowing for union propaganda exaggeration, this is quite a takeaway.
The pay cuts are significant. But the rule changes are sweeping, which amounts to a huge increase of hours and days of labor. Diverse retirement bennies are cut back.
At first glance, I can't imagine any but the most desperate people to want this job. I can't imagine any union voting for anything like this. This really seems like the most serious challenge yet for UA to keep flying.
And I really do want UA to make it.
