You have said nothing here, and that's not surprising.
There has been no law broken. What has happened is that the east pilots have used their leverage to apply pressure in a legal manner to prevent the implementation of the combined seniority list. Now, with the merger in process, we are about to test the waters of whether or not that list is indeed permanent or not.
East/west, no different. You enjoy slamming the worst rates in the industry, but when you look at actual facts, USAir was operating under a second bankruptcy contract, while AWA has always sucked with regard to pay and benefits BK or not.
Integrity is integrity, whether it is calling in sick when you aren't, whether you green slip with furloughed pilots or not, whether you either down pay rates on larger/capable aircraft to gain advantage in seniority list integrations, or whether you use your leverage as a larger pilot group to lawfully avoid implementation of a lopsided seniority integration.
Delta pilots are no smarter, nor have any more integrity than any other pilot group. UsAir east pilots are not scummy scabs, just a cohesive group of pilots utilizing ALPA merger policy to their advantage--as American pilots have, as SWA pilots have, as would any pilot group with a numbers advantage.
