I too am confused by the lack of action by "normal" Bassa members in allowing themsleves to be led down a delusional and destructive path. I can understand their need for recognised representation, but staying in BASSA is only feeding its leaderships ego and matyrdom personae.
At one point I could Sympathise with BASSA members still in the union but against it's course of action, now i cannot. Sheep to the slaughter.
Never underestimate the power of apathy. Most crew are just not "engaged" in this dispute. Many cannot even be bothered to vote in the ballots on IA. Taking a positive act like leaving the union is just too much hassle for many crew. This is a modern British malaise - how many could not be bothered to vote at the last general election? Yes they will pick up their mobiles and vote for the X-Factor, but to get involved in stuff that actually affects them is beyond the interest level of many in society.
