Supermarket giant Woolworths owes 5,700 staff as much as $300 million in underpaid wages dating back over nine years.
The underpayment of salaried staff was uncovered by Woolies in a review triggered this year by the implementation of a new enterprise agreement covering its supermarkets and Metro stores.
Woolies said on Wednesday it has only analysed two years of data but that the issue could date back to 2010.
