A California appellate court has ruled that Cornerstone Staffing Solutions, a transportation staffing company, cannot force a truck driver to arbitrate his wage and hour claims. The ruling is part of a number of cases, some of which have made it to the U.S. Supreme Court, that are calling into question the validity of class action waivers and employee arbitration agreements under the Federal Arbitration Act (FAA) and federal labor laws. Generally, the FAA supports the enforcement of arbitration agreements against employees in interstate commerce positions, but transportation workers are not covered under the FAA. According to the lawsuit, Tony Muro, a truck driver hired by Cornerstone Staffing Solutions, proposed a wage and hour class action that alleged that he and other employees were denied meal and rest periods and other benefits required under California law. Cornerstone argued that the employment agreement with Muro required him to arbitrate individually. Cornerstone claimed that, as a staffing company that derived 8 percent of revenue from logistics clients, it wasn't engaged in transportation which meant that Muro could not claim to be exempt from the FAA. However, the appellate court judge agreed with the lower court's decision that the company was at least partly involved in the transportation industry and therefore subject to the transportation industry exemption from the FAA.
