Melbourne-based firm Datasend Australia has been fined $35,000 for sacking workers who had complained about their pay.
The fines, which must be paid by May 9, are the result of a prosecution by the Fair Work Ombudsman.
Berry admitted he was also involved in Datasend dismissing a casual worker in 2007 because she had complained to a national regulator that her minimum hourly rate was being underpaid.
Fair Work Ombudsman executive director Michael Campbell said the case sends a message that breaching workers’ rights is a very serious matter.
“We will not hesitate to pursue companies and individuals who engage in this sort of behaviour,” he said.
