Section ERC 31.06 - Informal investigation or formal hearing

(1) PURPOSE. After a petition or stipulation has been filed, the commission shall conduct an investigation to determine whether the parties have reached an impasse on matters relating to wages, hours and conditions of employment or other matters subject to arbitration under s. 111.70(4) (jm)4, Stats. The investigation shall be conducted either by the commission or by an investigator assigned by the commission. The investigation shall consist either of an informal investigation or a formal hearing or both. If it is determined that the parties have reached an impasse, the commission or investigator shall obtain the parties' written final offers on the issues in dispute, and shall obtain a stipulation signed by the parties on all matters agreed upon to be included in the new or amended collective bargaining agreement. During the informal investigation or formal hearing, the commission or investigator may engage in an effort to mediate the dispute.

(2) INFORMAL INVESTIGATION PROCEDURE. If an informal investigation is conducted, the commission or investigator shall, after conferring with the parties, set a date, time and place for the conduct of the informal investigation and shall notify the parties of those arrangements in writing. The informal investigation may be adjourned or continued as the commission or investigator finds necessary. During the investigation the commission or investigator may meet jointly or separately with the parties or otherwise communicate with one or both of the parties, for the purposes described in sub. (1). Prior to the close of the investigation the investigator shall obtain in writing the final offers of the parties on the issues in dispute and a stipulation in writing on all matters agreed upon to be included in the new or amended collective bargaining agreement. If, at the time of the exchange of final offers or during any additional time permitted by the investigator, no objection is raised that either final offer contains a proposal not subject to arbitration under s. 111.70(4) (jm)4, Stats., the commission or investigator shall serve the parties, as set forth in s. ERC 10.07, with a written notice that the investigation is closed. The commission or investigator shall not close the investigation until the commission or investigator is satisfied that neither party, having knowledge of the content of the final offer of the other party, would amend any proposal contained in its final offer. Following the close of the investigation the investigator shall report the findings to the commission, either orally or in writing, as the commission may direct, and at the same time transmit to the commission the final offers and the stipulation received from the parties.

(3) FORMAL HEARING PRACTICE AND PROCEDURE. If a formal investigation is conducted, the commission or investigator, following communication with the parties, shall set a date, time and place for the conduct of the formal hearing and notify the parties by formal notice. The formal hearing may be adjourned or continued in the discretion of the commission or investigator. Hearing practice and procedure shall be as set forth in ss. ERC 18.06 to 18.08, except that the purpose and scope of the hearing shall be limited to establishing the facts needed to determine whether the parties have reached an impasse on matters relating to wages, hours and conditions of employment and other matters subject to arbitration under s. 111.70(4) (jm)4, Stats. Prior to the close of the hearing the commission or its investigator shall obtain and exchange the parties' final offers, and the parties' stipulation of agreed upon items, if any.
