Workers at the Dial Corp. plant needed to lift $35$ ?lbs $.$ ?of sausage at a time to a $30-60-$ inch height. Repeated movements could create injuries for some workers. Therefore, the company began a Work Tolerance Screen $($ WTS $)$ ?test for employee applicants. The applicants had to demonstrate strength ability. In the WTS $,$ ?the applicants had to perform $4$ ?times as many lifts as the current employees were doing and had no rest breaks as the current employees had between lifts. After the WTS was introduced, the number of women hired dropped from $50\%$ ?to $15\%.$ ?One female applicant took the test and passed it $,$ ?but wasn't hired, and other applicants came forward saying the same. In this case the court will hold that:
