It's a shame, because I, and many people I know would love to work for Qantas mainline, yet are not willing to give up our fulltime flying jobs elsewhere in exchange for a casual job at mainline. Too risky. I'd want a fulltime position for sure.
But I guess there are enough people out there who don't care about that and will happily take on a casual job and not mind that they don't get stable hours, any benefits or have Qantas paying their bills.
