Four men responsible for the relentless bullying of a teenage waitress  - who later killed herself - were today convicted and fined a total of $115,000.

The company which runs Cafe Vamp in Hawthorn, MAP Foundation Pty Ltd, was convicted and fined $220,000 after it and the four defendants pleaded guilty to charges issued by WorkSafe Victoria.

Magistrate Peter Lauritsen ordered cafe owner Marc Da Cruz, 43, Nicholas Smallwood, 26, Rhys MacAlpine, 28, and Gabriel Toomey, 23, and MAP Foundation to pay a total of $335,000.

A coroner last year implicated MacAlpine and the cafe owner, his company and two other former employees in the physical and emotional bullying of Brodie Panlock, 19, at Cafe Vamp between 2005 and 2006.

Coroner Peter White found she was treated in an "extremely aggressive and intimidating" manner at the Glenferrie Road business.

On the evidence of a former workmate, Mr White described manager Nicholas Smallwood and MacAlpine as "relentless in their efforts to demean her".

Ms Panlock, described at the inquest by a co-worker as chirpy and compassionate, killed herself in September 2006.
