What procedures should be put in place to deal with sexual harassment complaints?

To avoid liability for sexual harassment lawsuits, and indeed to prevent sexual harassment, employers are charged with establishing procedures for dealing with sexual harassment complaints. The procedures should be both fair and confidential, and must include a proper investigation of each complaint, including interviews with both the accused and the alleged victim, as well as any witnesses to the sexual harassment in question. Furthermore, the employer should take appropriate steps to separate the two parties (by reassignment, for instance) to prevent further hostilities or retaliation.
