Secondly, they want Q mainline costs down. So what costs can they bring down, labour & fuel. They've bought, well ordered, more fuel efficient acft....well, they think they are. For the labour, they need new awards. Q mainline guys/gals won't take a pay cut, so they bring in cheaper labour (Jetconnect, Jetstar & maybe a B scale).
It's all very well to get rid of the old awards in many areas - cute young things serving coffee for half the pay may reward the bottom line. But cute young things in every control seat of the cockpit just might have its problems...
