Dual Ground, the lady who 'complained' about the hats has left BASSA, prior to the strike, she is not one of the obtuse who swallow the BASSA line. She does not deserve your comments.
The point she is making is that BA are making lots of positive gestures towards Mixed Fleet, and treating the existing CC who backed BA by working throughout the IA in the same way as they are the strikers, in fact in 5 cases worse, as 5 strikers have become CSMs on Mixed Fleet.
The hat is no more than a symbol of those positive gestures.
Mind you, it's not clear how BA can treat the non strikers any better than strikers without breaking the law, but just treating Mixed Fleet the same as all the rest would be a start I guess. I daresay they will in time, it's all new at the moment.
