Sounds about right. So BALPA are fighting flexicrew by asking people not to join?! That's like asking people not to take a pay rise! Never going to happen. So that's that then. Only BALPA can stop it and they are going about it in a ridiculous ineffective way! Looks like it is here to stay for now.
BALPA should be looking at this urgently in my opinion but put some good brains on it for goodness sake!
