As early as 1990, a number of people with even a modicum of foresight were commenting that, after the Ansett and (then) Australian Airlines managements' undoubted overwhelming success in destroying the domestic pilots union, it would only be a matter of time before those same managements set about reducing the terms and conditions of both the international pilots and their highly paid newly-employed domestic pilots.
Managements' one error was to fall into the trap of believing their own propaganda during the head to head with the domestic pilots in that year we dare not mention here. In telling the public how few hours the average domestic pilot flew per annum, they set the bar for overtime to kick in for the new hires far, far lower than they needed to as they attempted to entice pilots to join or re-join the new 'lean and mean' domestic airlines. As much as they would have loved to renege on those (in their eyes) far too generous terms, they were stuck with them, for to have reneged, even three or four years down the track, would have been... shall we say 'industrially perilous'.
The way out was to create leaner, meaner (ie, LCC) versions of themselves. Australian Airlines (aka Qantas Domestic) created Jet*, which has slowly but inexorably intruded into both the Qantas domestic and international operations, with any growth in either division going to the far cheaper to operate Jet* rather than to the more expensive (dare i call them) legacy divisions.
I think it's only a matter of time until QF management reduces both Qantas Domestic and Qantas International into such small small 'rumps', (necessary - in management's eyes - only as long as they are tied by industrial agreements with staff unions or by government legislation), that those rumps can be safely (and quietly) shelved. then they'll probably re-brand Jet* as Qantas and Bob (or should that be Alan?)'s your uncle.
It's all been tried before. Look at the history of USALPA in the 1920s and 1930s. The Alan Joyce of the day back then could actually fly an aeroplane, but he was an equally divisive figure. His name was Eddie Rikenbacker.
Does that answer your question?
