(Businessweek) — The women who sought to sue Wal-Mart Stores Inc. for gender bias on behalf of 1.5 million co-workers said they will press their fight against the nation’s largest private employer in smaller lawsuits in lower courts and claims with the U.S. Equal Employment Opportunity Commission. The U.S. Supreme Court yesterday said the women failed to prove the world’s largest retailer had a nationwide policy that led to gender discrimination. The court deprived them of the leverage a nationwide suit brings, both in pooled legal resources and a potential multibillion-dollar verdict, forcing them to pursue claims on their own. “When I go back to work tomorrow, I’m going to let them know we are still fighting,” said Christine Kwapnoski, an assistant manager at a Sam’s Club in Concord, California. She had accused a male manager of yelling at female employees and telling her to “doll up” by wearing more makeup and dressing better while working on a loading dock.
