Just re this Qantas crisis: The unions are of course outraged about the fleet grounding and there is much talk that Alan Joyce is "holding the nation to ransom". They seem most annoyed by the fact that he's done the ol' switcheroo on them. But by grounding the fleet he's effectively "downing tools", which is something that unionists do with monotonous regularity. They think going on strike is fine for employees, but they can't stand it when employers do it.
As well as union outrage, many on the green left are seething with contempt for Joyce and what he has done. But isn't this a great thing for the planet? Think of all those greenhouse gases that are now not being spewed into the atmosphere. If the grounding keeps going for weeks or even months, it will do more to prevent global warming than the carbon tax could ever do. The effect of taking all those planes out of the air must be akin to taking 45 million cars off the road, at least. Bloke's a climate change hero, surely.
