UDP, MissM etc..
You might be interested in looking back at the last consultative ballot for the "final offer", where only 3,419 of your so-called 5/7000 strike force voted against the offer, with 1,686 voting for it. So if the current BASSA membership is 9,500 (ish) that leave 4,400ish undecided in July. It wouldn't take too much of a swing to get a vote of acceptance, give that some are clearly feeling weary of the whole dispute, and simply want it over.
I would also suggest that those strikers that didn't vote, did so because they were either fed-up that the IA had achieved nothing or as I'm sure you'll suggest
that they simply wished to take further IA, but by now I think they will be thinking this would be a foolish move.
