The Lilly Ledbetter Fair Pay Act of 2009 (S. 181) was presented to the President for his signature today. The Act is Congress’s response to the U.S. Supreme Court decision in Ledbetter v. Goodyear Tire & Rubber Co., 550 U.S. 618, 127 S.Ct. 2162 (2007). Lilly Ledbetter claimed that sex discrimination had resulted in lower pay than that received by male colleagues throughout her career. The court held that her claim was barred because she hadn’t filed a complaint within 180 days of an alleged discriminatory employment decision. The new law provides a plaintiff 180 days after any discriminatory paycheck to file a complaint.
