Please carefully read the following passage and discuss the ethics of the situations. Who acted ethically or unethically? Why?

A woman working in a kitchen of a mid-sized hotel restaurant approached the human resources director in her office and reported that the dishwasher was sexually harassing her. The sexual harassment purportedly involved making a number of suggestive comments to the kitchen worker, but involved no physical touching. After investigating the incident and talking with a number of other employees in the kitchen, the human resources director learned that no one had witnessed this behavior from the dishwasher and few believed that the dishwasher said the things of which he was accused. She also learned that the kitchen worker had a grudge against the dishwasher and told another worker she wanted to "get him."
