The whole idea many years ago was to replace the eight hour shift plus overtime, with a twelve hour shift but no overtime.
The idea was that everyone except the federal Treasurer won. There was a slight decrease in pay - which was minimal after tax, and in return you got a long weekend.
Trouble is, QF seems to think that they can negotiate a win/lose situation with them doing all the winning, and the LAME's doing all the losing. No one at QF has obviously worked out why the rosters are what they are in the first place.
