Equal Pay Act of 1963
In 1942, Republican congresswoman Winifred C. Stanley from Buffalo, N.Y. introduced H.R. 5056, Prohibiting Discrimination in Pay on Account of Sex, which did not pass at the time. The issue languished until 10 June 1963, when Congress passed the Equal Pay Act ("EPA" or the "Act") as an amendment to the Fair Labor Standards Act, to "prohibit discrimination on account of sex in the payment of wages by employers."

Andrews supports equal pay. 
and supported the Paycheck Fairness Act which recognizes and aims to eradicate gender-based wage discrimination that remains a problem for women in the U.S. workforce and to strengthen the Equal Pay Act. According to the U.S. Census Bureau, "women only make 77 cents for every dollar earned by a man" and The Institute of Women's Policy Research found that this "wage disparity will cost women anywhere from $400,000 to $2 million over a lifetime in lost wages."
