So after all this banter I come back to the original question:
If every other employee at the "old companies" got to use their years of service with equal value in relation to all the other employees, why do pilots think their entitled to different treatment using the who bought who argument to erase years of service?
Because every other employee group at the "old companies" did not get to use their years of service with equal value in relation to all the other employees. Your premise is false, and you are drawing a false conclusion.
First, the non-union employees. Did the 30 year janitor at AAA become senior to Parker? He has been around a lot longer, and maybe you consider him senior to Parker, however, he did not have the position and status Parker held, hence, he does not get Parker's job. Heck, even Lakefield, who held the status and had more years, did not get Parker's job.
Now, the unionized employees. All....I say...All.. had their seniority integrated at the "new company" according to their unions integration policy, or where the groups were in seperate unions by arbitration. What you actually want, is to forego the union policy, and do a special deal just for the east pilots. The pilots, just like every other group were to be integrated using the union's integration policy. That process was completed, then after the fact, you want a special deal.
Not a single work group was integrated as you claim, based soley on their years of service.
To sum, it is the east pilots who think they are entitled to special treatment, deserve to forego what every other work group has done, and deserve to leapfrog West seniority and status, not the other way around. This all AFTER they agreed to do it within the union's policy, and that had been completed.
