Answer 2

Answer:

The Equal Pay Act of 1963 is a United States labor law amending the Fair Labor Standards Act, aimed at abolishing wage disparity based on sex (see Gender pay gap). It was signed into law on June 10, 1963, by John F. Kennedy as part of his New Frontier Program.[3] In passing the bill, Congress stated that sex discrimination:[4]

depresses wages and living standards for employees necessary for their health and efficiency;

prevents the maximum utilization of the available labor resources;

tends to cause labor disputes, thereby burdening, affecting, and obstructing commerce;

burdens commerce and the free flow of goods in commerce; and

constitutes an unfair method of competition.
