Firstly it's not "my contract" as I don't work for US Air.
Secondly, "Who" is easy, "East Pilots". That's the problem. That's why you just Lost in Federal Court. USAPAs version of "democracy" is actually more accurately described as discrimination. USAPA fools exactly NOBODY and the flagrant use of the majority to railroad whatever policy suits them best is no different than the imposition of the old Jim Crow laws.
Unlike the perjured testimony of your noble USAPA cheerleaders, (the actual founders were too scared to actually show up) Elected reps. can and DO have the authority to bind the pilot group to agreements. Those binding agreements are not just binding on the reps themselves, (as absurdly testified to by your side) but in fact, are binding on the pilot group as a whole. So, that means that even if you didn't specifically agree to anything, your reps do in fact, speak on your behalf. I'll also point out at this point that a seniority list integration has never been subject to majority ratification and now, that is actually spelled out into Law. So if your argument is correlating the fact that because the majority of the pilots (98% East) voted to change the 65 thing in the West contract is proof that the majority can do as it wishes then you will be terribly disappointed to learn that you are talking about apples and oranges.
So then, by your logic, the majority vote can give the West a 50% paycut and give the extra proceeds to the East. Does that actually pass the common sense smell test to you because that is the line you are trying to connect. The law is clear. Binding means "Binding". Honestly, man to man, don't you find it disturbing that there is only ONE Lawyer that is telling you that you can win this? Moreover, that Lawyer has a horrible legal track record and is getting filthy rich on your dues money by telling the majority what they want to hear. If Seham was a venture capitalist, would you give him any money? Would you do so much as buy a life insurance policy from him? He brings to the table nothing but a string of very very expensive failures.
USAPA is nothing but a malignant cancer on your pilot group. They can't win. They won't win. They can't deliver on any promise, and they are absolutely predestined to fail miserably.
IOW, You have no Case. Never did.
