BA have already won against the crew. Accept VR before close today, if you don't, you'll be considered for a role on the new mixed fleet contract at c50% wage cut. if you are not selected for new contract, you will get statutory redundancy not the enhanced VR. if you are offered the new contract but decline, you may not be eligible for redundancy at all (don't believe this to be legal, pretty sure redundancy would need to be paid anyway)
standard BA bullying, but from what I hear, significant numbers of legacy crew have already taken he VR.
