(Reuters) - The Supreme Court hears arguments on March 29 in the largest sex-discrimination class-action lawsuit ever as Wal-Mart Stores Inc's female employees seek billions of dollars from the giant retailer.
Here is a chronology of key events in the case:
June 19, 2001: Betty Dukes, a Wal-Mart greeter at a store in Pittsburg, California, and five current or former female employees file a lawsuit in federal court in San Francisco, accusing the retailer of discriminating against its female employees by paying them less than men and giving them fewer promotions.
April 28, 2003: Attorneys for the women filed a motion for class certification and asked the judge to rule the case can go to trial on behalf of all women who worked for Wal-Mart in the United States at any time since December 26, 1998, a group believed to exceed 1.5 million current and former female employees.
