Job Classification Full-Time and Part-Time (a) When a new classification (which is covered by the terms of this Collective Agreement) is established by the Hospital, the Hospital shall determine the rate of pay for such new classification and notify the Local Union of the same within seven (7) days. If the local challenges the rate, it shall have the right to request a meeting with the Hospital to endeavor to negotiate a mutually satisfactory rate. Such request will be made within ten (10) days after the receipt of notice from the Hospital of such new occupational classification and rate. Any change mutually agreed to resulting from such meeting shall be retroactive to the date that notice of the new rate was given by the Hospital. If the parties are unable to agree, the dispute concerning the new rate may be submitted to arbitration as provided in the Agreement within fifteen (15) days of such meeting. The decision of the Board of Arbitration (or Arbitrator as the case may be) shall be based on the relationship established by comparison with the rates for other classifications in the bargaining unit having regard to the requirements of such classification. (b) When the Hospital makes a substantial change during the term of this agreement in the job content of an existing classification which in reality causes such classification to become a new classification, the Hospital agrees to meet with the Union, to permit the Union to make representation with respect to the appropriate rate of pay. (c) If the matter is not resolved following the meeting with the Union the matter may be referred to arbitration as provided in the Agreement within fifteen (15) days of such meeting. The decision of the Arbitrator shall be based on the relationship established by comparison with the rates for other classifications in the bargaining unit having regard to the requirements of such classifications. (d) The parties further agree that any change mutually agreed to or awarded as a result of arbitration shall be retroactive only to the date that the Union raised the issue with the Hospital.
