2009: The Lilly Ledbetter Fair Pay Act, signed by Presid

The Lilly Ledbetter Fair Pay Act, signed by President Obama in January 2009, allows women to file for wage discrimination suits within 180 days of their most recent paycheck, rather than from their first paycheck on the job. The law is named after Goodyear employee Lilly Ledbetter, who was awarded $3.3 million after discovering she made less than a male manager.
