Aranda works in an office environment with 50 employees. Once or twice a week, her boss Alden tells her she has great legs and that she should wear shorter skirts. He also tells her to let loose and open another button on her blouse once in a while. She asks him to stop and continues to wear knee-length skirts and keep her blouse buttoned to the neck. He never touches her and he never makes these comments when someone else can hear. When she gets her performance appraisal from Alden, he gives her an excellent evaluation and a raise. What should Alden do?
