Good for you Rosiegirl,
sometimes you have to do what you believe is right, and not just follow - or give in to - others. You may also have the chance to accept a deal direct from BA now you've resigned from Bassa.
If I was Willie I would let it be known that the previous offer would be made available to non Bassa members soon.
Remember that the senior Unite officials are fighting their own political battles at the moment and BA cabin crew are merely cannon fodder for their reputations and political ideals.
