Wisconsin Statutes Employment Relations (Ch. 111) § 111.375. Department to administer

(1) This subchapter shall be administered by the department. The department may make, amend and rescind such rules as are necessary to carry out this subchapter. The department or the commission may, by such agents or agencies as it designates, conduct in any part of this state any proceeding, hearing, investigation or inquiry necessary to the performance of its functions. The department shall preserve the anonymity of any employee who is the aggrieved party in a complaint of discrimination in promotion, compensation or terms and conditions of employment, of unfair honesty testing or of unfair genetic testing against his or her present employer until a determination as to probable cause has been made, unless the department determines that the anonymity will substantially impede the investigation.

(2) This subchapter applies to each agency of the state.
