From chatting to some ex ANZ pilots in recent times it seems their time to command is really long...I mean really, REALLY long.
If DECs were tried by the 'management' I would think there'd be a better than even chance of MASSIVE industrial action and MASSIVE resignations as peeps headed O/S were a command might be had in as little as 2 years in asia.
DECs are sometimes needed...in this case might cost ANZ lots more than they could afford.
