In Victoria you are allowed a witness or seconder to be present in such matters , I know of one guy that used this to his advantage ( he should have been fired) but started saying to the boss are you harassing me ? Then took two days off on stress leave .
He kept doing the same thing over and over every time he was spoken to , he found another job elsewhere and left eventually but that old harassment claim worked for this guy .
Harassment + workcover = bullying and no company wins this one .
