Gordomac,
It's because there's nothing to see.
The PPU represent a third of the pilots. 72% turned out, 71% voted for IA. That's a grand total of 17% of the pilots who voted for IA - some of whom might yet go to work anyway. That's why Virgin have said there will be no disruption.
The PPU have been holding industrial action for around 2 years now. No one has really noticed. They really got it wrong when they insisted on being the sole negotiating union, when two unions were present. No union has ever tried to oust the other union before, and it's totally against the principles of the union movement. Be this a lesson in how not to do things!
