The wages of "hundreds of thousands" of Victorians could be cut by up to a third under a secret Abbott government plan to abolish penalty rates and the minimum wage, Premier Daniel Andrews has claimed.

Mr Andrews says the federal government is planning to revive WorkChoices, leaving Victorian workers up to 33 per cent worse off.

Ahead of a submission to a sweeping Productivity Commission review of Australia's workplace system, State Labor has released figures showing 587,000 Victorians usually work at the weekend, 328,000 usually work overtime, and 157,000 usually work night shifts.

Using national figures adjusted to reflect Victoria's share of the working population, the submission, which is still being finalised, claims a Victorian machinery operator could lose up to $428 a week, an effective pay cut of 32.8 per cent, while a retail employee could lose up to $300 a week, a 24.5 per cent cut.
