A recent decision by the Supreme Court involving consumer arbitration agreements is likely to be applied to disputes involving arbitration agreements in employment agreements or handbooks.  In AT&T Mobility LLC v. Concepcion, the Supreme Court held that the Federal Arbitration Act preempted a California law allowing judges to invalidate class action waivers in arbitration agreements on unconscionability grounds.  The dispute in Concepcion arose out of a consumer transaction, but it is likely that the Court's reasoning and holding will be extended to other arbitration agreements, such as employment-related arbitration agreements.  You can read more about the Concepcion decision here.
