Of course they are training up the JQ engineers.Why is this a suprise to anyone?
If there is any industrial action by the QF engineers,then the JQ guys will just work the QF A330's,as it will be illegal for JQ engineers to not work the QF A330's. That part of Workchoices never made it out of the legislation changes since Labor has been in power.
And as far as management would be concerned, if they have the A330's flying as normal to schedule(supported by JQ), then that leaves the management LAME lackies to concentrate on the 737/767/747 fleet.
Don't be suprised if this is the EBA where the LAME-less tarmac issue comes to the front.
