FYSTI, thanks for posting the links to the EBA's etc.
It appears from afar that AJ is on a union busting exercise. I think we all agree on that.
It doesn't have to ba a union busting exercise though. It could be an agreement adjusting exercise. If your representatives can't get access to the CEO to discuss things, you need to get some fresh ones who can. If they won't negotiate to your long term career benefit, get some fresh ones.
QF wil roster you as efficiently to CAO 48 as they can, but if they can get JetStar to do the job for a lower cost they will.
The guys at the top of you list are sitting pretty, its the guys at the bottom who need to drive through change, as they will still want a job in 30 years.
Its your future. You either keep things as they are and watch QF shrink, or adjust and stay in a career.
