We have been going backwards for a decade as it has been structural and whilst they have not been putting a figure in their annual submissions, the coalition have put forward their hundred/s page documents with the overriding suggestion that the raise should be below the inflation rate.
Heard on TV recently that it is the worst in the OECD over that period, though I have not checked. We certainly are at the bottom end, if not last and long in need of better balance, much more in line with productivity increases.
Some employers will struggle, though if a business relies on paying workers the absolute bare minimum to survive, then the model itself is at best, somewhat inadequate. Big business wise, the disparity in pay from top to bottom is obscene and prioritising CEO pay and bonuses on the back of share buybacks etcetera is a model failing society.
