As you say, MF would have been here in one form or another because that is what BA wanted and the savings justified to them as a business, to push for it.
So it is here; what next?
You want a union and I am 100% behind that, but the union is all 9000 of you. You have accepted that their have been mistakes, everyone makes them, but you have to look at ways of making the mistakes as painless as possible and prioritise your issues.
Do you want each dismissal to be looked at by ACAS, or do you want to look at the guaranteed allowances? There are many things that could be addressed, but you have to be talking.
I am confident that Bassa will keep returning votes with the margin that they have, but I am also sure that BA will take the disruption hit regardless. But it doesn't have to be between the rock and hard place.
Withdraw the threat of action and offer to sit down and talk.
