If the figures of 20 Million savings a year per 1000 of old contract cabin crew converted to New contract, then one can see that it is a high stakes game.
I think most reasonable people can see that WW has got nothing to lose by his current course of action. If BASSA come up with their cost savings, he wins. If they sign a New contract, he wins. If they try to sit it out at home, he isn't bothered as his costs havent really changed. He pays the trip allowances to whomever flies the trip, whether it be a volunteer or the CC. I guess he is happy to have them sat at home, and leave the rest of BA staff to get on with making BA the World's Favourite airline again.
