Lefty Trucking Company and the American Truck Workers Union, the union that represented Lefty's workers, negotiated a collective bargaining agreement. In the CBA (collective bargaining agreement), it stated that if a Lefty Trucking Company 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, Lefty Trucking discharged employee Junior Ramos and the union appealed to arbitration. The arbitrator determined that Ramos violated a reasonably safe rule, but was not convinced that Lefty Trucking should have treated the violation more seriously than other rule violations. The arbitrator ordered Ramos reinstated. Can a court set aside this order? Explain?
