Michael Hill International said an initial review of its Australian retail employment contracts and rostering practices showed non-compliance with some industry requirements over the past six financial years and may cost the jewellery chain up to A$25 million to remedy.
The Brisbane-based company, which also operates stores in New Zealand and Canada, said it has begun a more detailed review of all employee records, rostering practices and payments, which will "take several months to complete."
The remediation of these issues is estimated to cost between A$10 million to A$25 million, the company said in a statement. Rectification and remediation is not expected to have any material impact on its underlying earnings for the year ended June 2020, or any future financial years, it said.
"We will move as quickly as possible to rectify any underpayments with those team members affected," chief executive Daniel Bracken said in a statement. "I will be in contact with all team members today to apologise on behalf of the company and to provide an outline of the process we are following to establish who is impacted."
In a separate trading update, Michael Hill posted a 0.1 per cent gain in June-quarter sales from continuing operations. It was the first three-month period in the 2019 financial year that they didn't fall, although the company noted that margin compression continues.
