Coles is under fire after a Western Australian store manager allegedly asked staff to come into work on a Sunday in exchange for pizza.

The strange request was apparently made via a letter posted on a notice board, where the manager asked 65 team members 'to give me four hrs free labour.'

'Yes, it is a big ask and I would not be requesting this unless it was absolutely necessary' the manager wrote, adding it was a 'personal request' and that there would be 'plentiful' pizza.

But the manager got in trouble after employees went to the local chapter of the Shop, Distributive and Allied Workers Association (SDA), ABC Radio Perth reported.

'As soon as he put that notice on the notice board SDA members started ringing us and we immediately got in contact with the manager and told him this was unacceptable and it would not be allowed,' SDA state secretary Peter O’Keeffe told the radio program.

An employee who has worked as a night worker at the store for four years told the program the manager was likely feeling the pinch from Coles higher-ups:

'Pressure from [regional management] does not result in an increase in hours to be passed on to the store to complete the work,' the worker said.

'The manager would have been pressured and may have felt this was the only measure to ask his staff for this free work.'

Coles said in a statement the request was 'completely out of step with Coles’ way of working'

Had all of the 65 workers showed up to do the job, they would have contributed a total of 260 hours of free labour.

Coles said in a statement to ABC the request was 'completely out of step with Coles’ way of working.'

'The notice, which was posted by a trainee manger, was quickly removed. Any team members working at the stated time will be paid as normal,' the statement continued.
