Some supervisors are threatened by someone's expertise, look for a reason to fire them, find one, get the support of management and take it to an HR hearing. This is one reason why a good HR department is required, and the lack of them can be a problem for the unwary (or opportunity for the psychotic) at a smaller outfit. They will / should defend the company against a news story of employee bullying.
