Cаrlа wоrked in аn оffice fоr a construction company. She worked at the company for ten days. She claims that three times during those ten days a construction worker came into the office and said, “Hey, Gorgeous! How are you today?” Carla just smiled and did not respond when he said this nor did she inform a supervisor. Nevertheless, this comment irritated Carla considerably, and she strongly believed that such conduct constituted sexual harassment. Consequently, she quit her job and sued the employer for hostile work environment sexual harassment. Which one of the following statements is most likely correct with regard to this situation?
