Firstly let me say, I hope the NZ guys/gals get everything they are fighting for.
They deserve to get equal conditions to those of their colleagues on this side of the water.
In saying that, be warned. This is not 89. There is very very little group solidarity in this day in age of aviation when it comes to job risk/security. There may be the odd person who will go sick or use an URTI etc. however, 99% of VAA crew if rostered to do a VA pacific flight to an island WILL do it.
They will not risk their job. I am certain of that. So don't be fooled. Do whatever you have to but do it with your eyes wide open. Good Luck.
