Wal-Mart hit by discrimination case
Bentonville, Arkansas: Wal-Mart could face the biggest sexual discrimination case in US history after a court ruled that more than 1.5 million women who have worked in Wal-Mart's US stores since 1998, could join a class-action suit against the retailer alleging they were discriminated against in terms of pay and promotions. "This is just another step in what will be a very long process and we are still in the early stages of the case," said Theodore Boutrous, partner at Gibson, Dunn & Crutcher and lead counsel for Wal-Mart's appeal. "We are optimistic about our chances of obtaining relief from this ruling as the case progresses."
