Except where modified by this MOU, the County retains the exclusive right to determine the methods, means and personnel by which County government operations are to be conducted; to determine the mission of each of its departments, boards and commissions; to set standards of service to be offered to the public; to administer the Civil Service system; to classify positions; to add or delete positions or classes to or from the salary ordinance; to establish standards for employment, promotion and transfer of employees; to direct its employees; to take disciplinary action for proper cause; to schedule work; and to relieve its employees from duty because of lack of work or other legitimate reasons. The exercise of County rights does not preclude employees or the Association from consulting or raising grievances on decisions which affect wages, hours and other terms and conditions of employment. The County reserves the right to take whatever action may be necessary in an emergency situation; however, the Association, if affected by the action, shall be promptly notified. The HRD Director shall, on request of either party, refer questions regarding the interpretation of this Section which cannot be resolved between employee and management representatives to either the Board of Supervisors or the Civil Service Commission for hearing and final determination, depending on which body has authority over the matter in dispute. In no event shall such dispute be subject to the grievance procedure of this MOU.
