Maybe it's like Airservices Australia, who break out in a rash of TIBAs every time there's an overtime ban, ie overtime is a fundamental part of their rostering system. Is that the case in Qantas maintenance as well?
I said that you may not be entitled to dictate what occurs
I'd be very surprised if anything I do, say or publish makes an ounce of difference to what occurs at Qantas or any other airline, so I suspect that's highly unlikely.
