In my opinion, if whathisname eventually wants Joyces job, then he will have to convince the investors that he is at least as tough on unions as Joyce proved to be. Anything less than complete victory for management is unacceptable.
Considering that Joyce shut the airline to screw over the engineers, I assume that a similar grandstanding event is available to QF already because that would allow them to use their most potent weapon - the QF group public relations team who have their hooks embedded into every media organisation in the country. Think tearful stranded pax on morning TV - and its all the fault of greedy, lazy, Jetstar pilots. Then expect thunderous threats from ScoMo.
Be prepared for it.
