Parker said the company would let the pilots work out pilot seniority, he did not say he would expose the company to litigation they have a good chance of losing, to support the usapian theory of how to take from your fellow employee. Ever notice how he answeres these questions with the fundamental understanding that there are two sides in the arguement, not just the one sided usapian premise of they are the only ones that count, and can cram down anything they wish in a contract? Parker knows the West is in the right here, and is waiting for east "acceptance", not the other way around.
Reconcile what you say above with what Kirby said in a 'Crew News' visit some time ago. I'm sorry I do not have the exact quote (and the said session in no longer available on Wings) but Kirby said, in effect, 'that the NIC was not going to work here'. And I believe this was said after Parker 'accepted' the NIC.
I would say Parker is waiting for another group to come to terms with "acceptance".
