Well, if they dont then BALPA in any meaningful form will cease to exist.
I think BALPA have made a very reasonable counter-offer to BA, which BA would be well advised to accept. If they dont, I guarantee a strike.
As an aside its odd that, for defending my contractual rights, I can be termed both a "Comrade" and a "Fascist". BA squandered millions and, in effect, expect the staff to pay for it. That is about all I have said, and I am certain that BA staff will not underwrite the mistakes of the past by surrendering their economic futures. I would add that BA has become a corporate bully of the worst kind, who'se treatment of flying staff in particular has seemed calculated to provoke the strike that will be not long in coming.
