Arbitrator to hold hearings
Wis. Stat. § 111.57
in effect(1) The arbitrator shall promptly hold hearings and shall have the power to administer oaths and compel the attendance of witnesses and the furnishing by the parties of such information as may be necessary to a determination of the issue or issues in dispute. Both parties to the dispute shall have the opportunity to be present at the hearing, both personally and by counsel, and to present such oral and documentary evidence as the arbitrator shall deem relevant to the issue or issues in controversy.
(2) It shall be the duty of the arbitrator to make written findings of fact, and to promulgate a written decision and order, upon the issue or issues presented in each case. In making such findings the arbitrator shall consider only the evidence in the record. When a valid contract is in effect defining the rights, duties and liabilities of the parties with respect to any matter in dispute, the arbitrators shall have power only to determine the proper interpretation and application of contract provisions which are involved.
(3)
(a) If there is no contract between the parties, or if there is a contract but the parties have begun negotiations looking to a new contract or amendment of the existing contract, and wage rates or other conditions of employment under the proposed new or amended contract are in dispute, the factors, among others, to be given weight by the arbitrator in arriving at decision, shall include all of the following:
1. A comparison of wage rates or other conditions of employment of the utility in question with prevailing wage rates or other conditions of employment in the local operating area involved.
2. A comparison of wage rates or other working conditions with wage rates or other working conditions maintained for the same or similar work of workers exhibiting like or similar skills under the same or similar working conditions in the local operating area involved.
3. The value of the service to the consumer in the local operating area involved.
4. The overall compensation presently received by the employees, having regard not only to wages for time actually worked but also to wages for time not worked, including, without limiting the generality of the foregoing, vacation, holidays, and other excused time, and all benefits received, including insurance and pensions, medical and hospitalization benefits, and the continuity and stability of employment enjoyed by the employees.
(d) In addition to considering the factors under par. (a), if a public utility employer has more than one plant or office and some or all of the employer’s plants or offices are found by the arbitrator to be located in separate areas with different characteristics, consideration shall be given to the establishment of separate wage rates or a schedule of wage rates and separate conditions of employment for plants and offices in different areas.
(e) The enumeration of factors under pars. (a) and (d) shall not be construed as precluding the arbitrator from taking into consideration other factors not confined to the local labor market area that are normally or traditionally taken into consideration in the determination of wages, hours, and working conditions through voluntary collective bargaining or arbitration between the parties.
