The U.S. Women's Chamber of Commerce is joining the fight in the largest employment discrimination class action suit in American history...and actively seeking redress for the giant retailer's treatment of female employees over the past 25 years. The U.S. Women's Chamber of Commerce opposes Wal-Mart's recent petition for a rehearing on the suit's class action status in this historic case...and has expressed this view through the filing of an amicus curiae (friend of the court) letter with the United States Court of Appeals for the Ninth Circuit.
