The Lilly Ledbetter Fair Pay Act is a U.S. law enacted in 2009 that aims to address wage discrimination. Named after Lilly Ledbetter, a former Goodyear employee who discovered she was paid less than her male counterparts, the law allows workers to file pay discrimination claims within 180 days of receiving a discriminatory paycheck, rather than from the date of the initial discriminatory decision. This act was significant because it expanded the time frame for employees to seek justice for unequal pay based on gender, race, or other protected characteristics. It reinforces the principle of equal pay for equal work, promoting fairness in the workplace.
