Looks like the majority are not resigning from QF. Many will continue leave and fly elsewhere (China Southern, JQ Vietnam, Japan, Middle East and so on). I don't think the results today are bad enough to scare anyone into clutching to Jetstar for salvation. The prospect of a financial clearing of the decks at Qantas is actually reassuring to a degree.
The flip side of that is 10 years plus of redundancy provisions in Qantas far outweighs a few in Jetstar and if it gets that bad we are all screwed.
