Baggersup, there is an opposite take from yours (post 642) on this situation set forth on the CC forum above in posts 1218 and 1219:
It is Unite that have withdrawn the ballot not Bassa and Amicus. Unite don't want it to go ahead because Bassa and Amicus have both recently said they will encourage a NO vote. Unite don't want a NO vote for the offer because that would make it hard for them to deny Bassa and Amicus another strike vote.
There is additional reasoning in these two posts which I believe is more accurate interpretation than yours in which Unite has predicted a 'Yes' vote on the BA proposal. And I recall the wording used by Woodley about the ballot was “suspended”, pending talks between Unite and the two branches.
