Roll on Friday indeed.
The 3-4000 former ST losers will almost certainly vote for IA. (It seems to me they see it as their only chance to fight their hated employer BA in revenge for being hugely outmanoevered by BA up to to this point.)
The question is what proportion of the remaining say 5-7000 members will vote no (or bother voting at all
).
All will be revealed tomorrow.
