The folks I know who took the job at Voz (and the ones I know who are keen to get in) are working crap jobs in crap places of the world and will jump into a Voz 777 in oz because there is no other 777 job on offer at home.
And this folks is why conditions will never improve at Voz!
While people are knocking down their door on the current conditions - why would they?? I don't think the current contract includes any pay rises at all. Maybe someone can confirm this with the exact wording from the contract?
