Cynthia, a thirty two-year-old woman, applied for a job as a delivery van driver for Federal Express. Cynthia was not hired because she did not meet the company requirement that all delivery drivers must be 5'7" tall and weigh at least 170 pounds. Cynthia is 5'6" tall and weighs 145 pounds. Federal Express feels the minimum physical requirements are valid because the delivery people must move heavy loads in making pickups and deliveries. Cynthia sues. Has Federal Express violated the Civil Rights Act? Please explain.
