Rose believes she is being harassed in the workplace by Stan. He keeps making sexist comments to her and vulgar gestures to her. Rose reports this to HR, but HR ignores her complaints. Stan in this situation is a co-worker and not a superior to Rose.

Would this be harrasement in the workplace? What defenses would the employer have if any or what should the employer have done differently? If Stan was Rose's supervisor and not co-worker, how would this change the situation.
