By BA telling the truth about the financial situation the members have been driven into the arms of the union?
No, I don't believe that. Their fear is irrational, BA have attempted to rationalise with them. Having heard the harsh realities of life from BA, CC have chosen to listen to the siren call of their union and preferred to bury their head in the sand rather than accept change. The union has promised to negotiate a deal which will miraculously provide BA with the savings it is seeking whilst still preserving CC's T&Cs.
I predict the meeting on Thursday will promise more of the same (after thanking the membership for their 'brilliant support' 'fantastic turn-out' which has forced WW back to the negotiating table where their 'hard-working reps' will thrash out a new deal which will consist of virtually all of BA's wish list but presented as a 'win' for BASSA)
