Discount retailer Dimmeys has been criticised for reportedly sacking a number of its Victorian workers through the mail.
The Shop Employees Union says letters were received last night, telling workers they were no longer employed.
Dimmeys employs more than 500 people, but the union says it is not sure how many workers have been sacked.
State secretary Michael Donovan says the company did not provide any warning.
“Most employers would give us an indication if there were problems likely to arise in respect to redundancies,” he said.
“But that hasn’t happened on this occasion. There’s been no engagement at all.”
Mr Donovan says employees deserved to be told face to face.
“Anyone who is made redundant is entitled to have the company to get them together and actually tell them face to face,” he said.
“It’s really quite extraordinary that people have to go home at night and open up a letter and find on Friday night that their job finishes up on Sunday and there’s no work for them on Monday.”
