The Union genuinely seem to think what they are doing is for the best, so I can't fault them too much for that (I'm sure many will disagree). However, from the briefing I attended, they indicated that they may not support us on taking further action in the case of a no vote.
If the vote form the membership is for a no vote, that stance is unacceptable from a Union who we pay for and should be there to support us.
