Sure, you can take care of just yourself, cause you're all right, without sticking together to get something first. Did you forget that whole contract compliance threat hanging over the company not too long ago, because we stuck together?
Since they want something from you (consent form) then have they or you schedule your negotiations to find out what they are offering you in return for altering your COS?
Or you can just give away what little leverage you have to maintain the status quo, with no written agreement as to what will happen, how it will happen, what it will mean and how it will affect you when the situation (a/c, routes, basings, FTLs, RPs, etc.) changes in the future?
Come on, man...you'd be a fool to give in at the first offer in any "sale" of what you have that they want...specially when you are interested in just giving it away. Short term thinking, with short term memories, it seems...
