Jarvy:
I'm not so sure that Unite will immediately go for a strike vote.
Those numbers (their weakest so far) will not sustain an effective industrial action. Observing BA's growing ability to increase operations during each of the previous IA's and their expectation to fly 100% of their long haul operation during any subsequent action I am not so sure that Unite is going to be anxious to ballot.
BASSA of course could very well be an example of "Fools rush in where Angels fear to tread".
