An Ohio woman who sued Wal-Mart for sex discrimination says she's pleased the suit has been granted class-action status. Micki Miller Earwood of Springfield was fired in 2000 after questioning the company's pay and promotion policies. Earwood is one of four Ohio women who gave sworn statements to plaintiffs' attorneys suing the retailer. On Tuesday, a federal judge in San Francisco granted class-action status to the lawsuit. The suit will now represent as many as one-point-six (m) million current and former employees. The suit claims Wal-Mart set up a system that often pays female workers less than their male counterparts for comparable jobs and bypasses women for promotions. Bentonville, Arkansas-based Wal-Mart is the world's largest private employer.
