Carnage Matey, just to be clear, the new fleet was taken off the table a few months ago then reintroduced in an e mail from the leader of IFCE to the cabin crew community , then decided to tell the cabin crew community they were willing to look at alternatives in a video available on the BA intranet. If you think that's negotiation so be it ,your entitled to your opinion.
As for who refused to meet with who during the ACAS meetings, I very much doubt you or anyone on the forum were actually present at the time. so it boils down to who's side of the story and the rumour mill you decide to listen to and make a judgement.
