Carol Lee was a local sales representative for CableCo, a national cable TV network. When a vacancy in the position of regional sales manager arose, Carol applied for the job. Her supervisor told her that the job involved a lot of overnight travel, and because she had small children, it “wouldn’t be right” for her. The position was given instead to Tom Matthews, a single male with no children. Has Lee’s employer violated Title VII’s prohibitions against sex discrimination? Explain.
