Marvy, have you actually read the full press release or staff briefing from the company or are you just reacting to the snippet posted above?
If you have read the company release or contacted your union you would find that it is a discussion between the company and all affected unions. So therefore should the staff have objections concerns then the unions can voice this to the company. Obviously the company is unlikely to try and push this through if all the staff are going to go on strike. Seeing you have concerns you could ring Alpa or the Federation and let them know how you feel.
For that matter do you actually know what the Freedom contract is? The B scale might not seem that bad when you read it. BTW the B scale would only work for fleets already negotiated in the contract. So I think alarm bells would start ringing if Freedom management wanted to start putting in 767 777 and 747 pay rates into the freedom contract.
Happy flying dude.
