Does she want this guy immediately fired no question asked?
At the company I work for, the stated policy is that upon receipt of a harassment complaint, the accused is immediately put on administrative leave (with out pay) and the complaint is forwarded to the local prosecutor's office for investigation. If the prosecutor clears the accused, then he is re-instated. Otherwise, he is fired. In the even the accused is cleared AND the prosecutor determines the complaint was filed with malicious intent, then the accusor is fired.
The company also has a policy of protecting the victim's privacy, so I don't know if the above procedure has been used.
The policy may seem harsh, but the company's legal department takes the position that it is better to err on the side of the victim, even if the accusations ultimately prove to be malicious.
