For years, New York law prevented females from working at night. Therefore, Corning Glass Works employed male workers for night inspection jobs and female workers for day inspection jobs. Males working the night shift were paid higher wages than were females who worked the day shift. When the federal Equal Pay Act was enacted, Corning began hiring females for night shift jobs, but it instituted a “red circle” wage rate that permitted previously hired male night shift workers to continue to receive higher wages than newly hired night shift workers. Does this violate the Equal Pay Act? Corning Glass Works v. Brennan, Secretary of Labor, 417 U.S. 188, 94 S.Ct. 2223, 41 L.Ed.2d 1, Web 1974 U.S. Lexis 62 (Supreme Court of the United States)
