Ford Automotive and the United Auto Workers Union, the union that represented Ford's workers, negotiated a collective bargaining agreement. In the CBA (collective bargaining agreement), it stated that if a Ford Automotive employee was discharged for a workplace rule violation, the matter would be submitted to an arbitrator. The CBA agreement also limited the arbitrator to determine whether the rule was reasonable and whether the employee violated it. Later, Ford Automotive discharged employee Mark Grewal and the union appealed to arbitration. The arbitrator determined that Grewal violated a reasonably safe rule but was not convinced that Grewal should have treated the violation more seriously than other rule violations. The arbitrator ordered Grewal reinstated. Can a court set aside this order? Explain?
