More than 100 Wal-Mart Stores Inc. workers paint a similar picture in sworn complaints about the company: Local managers made sexist decisions about promotions and pay, and top officials did nothing to stop them. The U.S. Supreme Court is poised to consider whether those allegations warrant a class-action suit of…potentially…more than 1 million female Wal-Mart workers. At issue is whether the claims point to a companywide practice of alleged discrimination or instead amount to isolated anecdotes at a company with almost 1.4 million employees. The case…marks the court’s first look in 12 years at the standards for certifying a class action… More than 20 companies are supporting Wal-Mart at the high court, including Intel Corp., Altria Group Inc., Bank of America Corp., Microsoft Corp. and General Electric Co.
