Clarified - I don't think the Company are interested in a way forward with BASSA at all - see DaDog post earlier:-
We do not think BA management would dispute that it is seeking to exclude unions form management decisions. We think BA’s leadership is keen to force cultural change on the institution and breaking established union management links is key. Rebasing management of the company so that decisions are made in head office and not by labour, is a key part of the management change being sought.
The money issue / crewing levels are all by the by. It's about who runs the Company. The only way management can get that power back is to break the union - the earlier the better as the current financial climate helps their cause.
BASSA have fallen into the trap a treat - they have called for a strike. BASSA have to hope now that the Company block the strike using a legal challenge so they can save face.
However, better for the company to allow the strike to happen and break it - job done, power regained as no more BASSA.
