They worked four years to get the TA, they forward the TA to the membership as the best they could do, the membership rejects the TA as not good enough, you state it "sucked", after that rebuke what do you expect them to do? The right thing to do is resign and allow those who think there is more meat on the bone an opportunity to go get it.
If the TA "sucked", why would you want them as your negotitors? Obviously you think the product they produced after four years was far below expectations. Why not volunteer yourself to fill their shoes?
I'm not sure that I agree. Had the TA failed by a large margin I could see your point, but the TA failed by less than 1%. That's an indication to me that the current NC should go back to the table and fix the few items that the pilots are unhappy with. With such a close vote, I'd bet that a few small adjustments to scope, lance CAs, and ELITT would yield a landslide ratification vote. But with the resignation of the NC, they'll now be set back by 6+ months, most likely.
