From 2001 to 2006, workers brought nearly 40,000 pay discrimination cases. Many such cases are likely to be barred by the court’s interpretation of the requirement in Title VII of the Civil Rights Act of 1964 that employees make their charge within 180 days “after the alleged unlawful employment practice occurred.”
In a vigorous dissenting opinion that she read from the bench, Justice Ruth Bader Ginsburg said the majority opinion “overlooks common characteristics of pay discrimination.” She said that given the secrecy in most workplaces about salaries, many employees would have no idea within 180 days that they had received a lower raise than others.
According to NPR, one of the cases cited as “precedence” for this ruling has been overturned by congress. If you find the details, link it up.
