Up to 140 jobs will be lost at The Warehouse, as the country's biggest retailer restructures its store leadership.
The Warehouse said it was the first change of its kind in 15 years and would lead to job losses across its 92 stores.
Chief executive Pejman Okhovat said the changes would lead to increased staffing levels at peak times, better leadership support during trading hours, improved sick and holiday cover and better-defined career pathways for team members.
He said the company would make an effort to re-deploy as many team members as possible into vacant roles, but it was expected to be between 120 and 140 fewer full time equivalent roles.
The new structure should be in place early next month.
First Union said workers would have to re-apply for their jobs over the next few weeks, before finding out if they will actually be made redundant.
