Failing to address workplace sexual harassment (or any of the other potential workplace issuesthat arise from failing to act on information relating to this kind of issue between coworkers) merely because a related criminal complaint was dismissed is a good way to get into deep liability, since sexual harassment (and many of the other sources of liability which could become relevant based on a failure to act) don't require the necessary elements of the crime of rape, and as a statutory tort rather than a crime, have a lower standard of proof.
