I was head of HR for 2 large companies, and also had access to anything and everything. He is certainly not the top of the ladder, and if what you are saying is true, the company can be liable for his actions.
You might want to contact another lawyer, and if it is true what he doing and the company is allowing it, you won't have money issues for long. His actions can be traced. Turn the focus from him, to the company for the wrong doing of their HR manager.
