Desertia is quite correct in reminding me that BASSA is a branch of UNITE and whatever the PCC could achieve in breaking into the BASSA leadership, you would still be a branch of UNITE.
I think my slight concern is that however battered BASSA become, there will always be a following and with that compulsory recognition by BA. Negotiating with BA with three organisations representing the workforce is going to be troublesome.
I wish the new PCC well, I really do.
