Well, considering that everything the unions are not willing to give will probably be awarded to the company by the bankruptcy court, what is your plan B? You say you are not going to give anything more. Now, just voting no on a TA does not constitute "not giving anything more." If the TA passes despite your no vote, you are still stuck with a concessionary contract. What is your Plan B?
I know I keep hearing f/as say they are not giving another dime, but when I ask if that means that they are going to quit if the company gets what it wants--either through negotiations or through the court--they just look at me with a blank stare as if someone had just asked them to clean the plane when it isn't a C-bill.
