Investigating sexual harassment is something that should be taken quite seriously. If a victim of sexual harassment has made a complaint to a supervisor, that supervisor should begin to investigate the incident immediately. Employers who ignore complaints made by employees of sexual harassment might also be found guilty when the complaint is taken to a higher level. Sexual harassment must be conduct that is not welcomed by the victim. If it can be proven beyond reasonable doubt that a victim encouraged sexual advances, then the advances cannot be deemed to be sexual harassment. In 1999, the EEOC put out a policy concerning sexual harassment that includes information on how to investigate claims. The EEOC recommends that while investigations are in process, victims should not be forced to continue to work with the harasser. In addition, it is not lawful to punish a victim in any way for filing a complaint that begins a sexual harassment investigation.
