Here's an idea.
A common EBA (pilots) over the DJ group. VA/
VB/PB. New hires will be offered S/O positions on international, or EJ on domestic, depending on their aptitude. Everyone gets a seniority number, and based on that are given the right to bid for either a type transfer if a vacancy arises, or the opportunity to qualify when a command comes up, without of course displacing those already on type or base. Thus creating a "REAL" career path within the organisation.
Wages and conditions of employment comensurate with the high levels of professionalism expected from both the company and the travelling public. Nothing like the stellar bucks and bonuses made by those non productive types in the upper echelons of power (hopefully soon to weeded out anyway), but enough to kick-start a family and with time and progression build a life worthy of all the sacrifices made so far.
Expensive? Yeah maybe, but I'll tell you one thing, the training costs associated with replacing those leaving for "Greener pastures" would virtually disappear, and a professional workforce that truely would be proud to say "I'm a Virgin Blue (or whatever it becomes) Pilot."
Or, they could just leave it the way it is!
