Wanda Collier worked for Turner Industries Group, LLC, in the maintenance department. She complained to her supervisor that Jack Daniell, the head of the department, treated her unfairly. Her supervisor told her that Daniell had a problem with her gender and was harder on women. The supervisor then dismissed her complaint. One day, Daniell confronted Collier, pushing her up against a wall and berating her. After this incident, Collier kept a male co-worker with her at all times. A month later, she was fired. Could Collier's treatment constitute sexual harassment? Explain
