The former operator of a commercial laundry treated staff ''shamefully'' when he subjected them to physical, psychological and verbal bullying over two years, a County Court has found.

Judge Mark Taft said the conduct of Kevin James Andrews represented a ''high water mark'' of denigration, humiliation and verbal abuse of his employees, and which all contributed to their high stress, anxiety, worry, fear and low self-esteem.

Mr Andrews, 61, had appealed a Magistrates Court conviction and sentence for workplace bullying under the Occupational Health and Safety Act 2004 in which he was originally fined $50,000 and ordered to pay $50,000 costs.

But in handing down his finding in Mildura on Thursday, the judge found Mr Andrews engaged in ''repeated and unreasonable bullying behaviour'' at Mallee Laundry and Linen Services between January 2007 and January 2009.
