wal-mart sex discrimination

whats happening in wal-mart is that a group of women that worked in wal-mart for a long time are sueing them for discrimination getting paid" less than men and and gave them fewer promotions." this happenign everywere not jsut wal-mart ,but since this is the biggest company in America without a union it was easier to target them. the majority of workers in Wal-mart are women so they felt they should do something about this problem.
