To be fair to MissM and the average cabin crew, withdrawal of Staff Travel for IA has been BA standard procedure for years, decades even. It has so far always been restored when the IA was over. So one can see why cabin crew would assume the same would happen this time, even though WW was far more public, positive and specific about it being permanent than any CEO I can recall. Especially as BASSA no doubt convinced themselves they would ground BA, as again they always have been able to in the past.
From something WW was quoted as saying by a non striking CC during the strike, over on the other thread, WW feels the loss should remain, as the non strikers, non union members and 'no' voters, are all going to get lumbered with whatever the final lesser deal is that BASSA have caused by not negotiating etc. So it seemed to WW fair that the strikers should lose something extra, given that they have caused the non militants to lose something, ie a better deal.
