There’s a suit against Wal-Mart that going to the Supreme Court. The only thing being decided is whether or not the plaintiffs can bring the case as a class action. It involves up to 1.6 million women, in 3,400 stores and 170 job classifications. Too big, too difficult to manage, Wal-Mart claims.

But if there is no class, will Wal-Mart ever have to change their practice of discriminating against women? Will 1.6 million women sue? Or 3,400, or 170? Not likely, because most women Wal-Mart employs don’t have the resources.

Being poor is not a license for employers to discriminate.
