Labor has already hinted at AWA exemptions for the mining industry and as soon as he said that Dixon was into it saying that Qantas was a special case too and that they should also be exempt. Soon enough everyone will be on the "exemption" bandwagon.
What could happen is that Rudd will get into power then claim that it's such a big mess, the liberals have stuffed up the country blah blah so therefore we can't go ahead as it is in a bigger mess than what we first expected. Or they will just stall for a few years until everyone forgets about it. Happens in every single change of government election in state and federal level.
If you are voting for Rudd on the basis of industrial relations I would be looking into it very carefully.
