Killing the Goose that Lays the Golden Paycheck?

I have never fully understood this kind of behavior:

American Airlines Inc.'s flight attendants voted to turn down their financial concession agreements with the Fort Worth-based company, following the approval announced by pilots and transport workers earlier in the day, according a report by Dow Jones Newswires.

The rejection by the Association of Professional Flight Attendants could lead to a bankruptcy filing from the world's largest airline.

If your compnay goes bankrupt, you aren't going to get the deal you want anyway, and indeed, you are likely to lose your job.
