But wait. YOUR majority vote determined the make up of YOUR MEC, who then agreed not to negotiate or be reasonable, and agreed to force binding arbitration, and then agreed to abide by the results.
So the original statement of you not being able to get past binding arbitration is more accurate. That's where your collective actions bit you in the a$$, and that is where your responsibility for this whole mess, (including the lack of unity) starts.
Again as the 9th commented in its opinion, ALPA structured its policy in a way that allowed an indefinite veto, which clearly infers that ALPA policy supported the concept of majority rules in acceptance of the "proposal". I am sure if it makes to trial again, USAPA will be free to show video and letter evidence imploring US Airways pilots not to leave and they were protected from ever accepting the award until a compromise could be reached. Obvious the no trust level existed for US Airways east pilots as they rejected the repeated appeals of various ALPA spoke persons including the president that the "majority rules vote" protected their rights until some solution could be brought forth that would be accepted.
USAPA has a different mandate and the court reminded it of its good faith responsibilities but also made it clear it free to pursue negotiations to find a ratifiable agreement. It really doesn't matter what your view or definition of "good faith" standards are, only what the precedent opinion set forth.
