I recognise the point made above that BALPA have made every effort to adopt the most ‘reasonable’ approach throughout this process. They deserve credit for that.
However ...... accepting also that there are almost certainly things happening behind the scenes, to which few (if any ?) of us are privy, I do think there comes a point when BALPA could be deemed to be prolonging uncertainty - by which I mean, more so than BA. One could say that BA have at least made their position clear (wrongly or rightly) with the reported ‘final offer’ and that BALPA should therefore have decided by now what their own final position is, one way or the other.
I wonder whether BALPA are perhaps risking (some) loss of support with what might be seen as prevarication .... ?
