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."
Equal Pay Act 1970
In 1999, trades unions negotiated Single Status job evaluation for local government, hoping that this would enforce the Equal Pay Act without needing to take numerous pay claims to industrial tribunal. Single Status was intended to establish whether jobs were of equal value, and bring in a pay model which would remove the need for equal pay claims. Jobs which had previously been classed as manual or administrative/clerical would be brought together under one pay scale and one set of terms and conditions.
