Also the idea that the negotiating would survive a rejected TA is laughable. Look back at the history of rejected TA's and most have the committee resigning (here come the throw the bums out lines

).
They would have no leg to stand on at the negotiation table and zero credibility with any mediator. Conversation would go something like this:
NEG com: We need to define entry requirements for 4a2b
Company: What do you mean, it worked great no one was furloughed, your junior guys aren't complaining.
Neg com: Yes they are, everyone is ****ed off
Company : How do you know, you couldn't even get a contract extension passed
Neg Com: but..
Mediator: He does have a point........
Nothing is accomplished except wasted time and energy.
