Wisconsin Statutes Employment Relations (Ch. 111) § 111.115. Notice of certain proposed strikes

(1) In this section, “strike” includes any concerted stoppage of work by employees, and any concerted slowdown or other concerted interruption of operations or services by employees, or any concerted refusal of employees to work or perform their usual duties as employees, for the purpose of enforcing demands upon an employer.

(3) Where the exercise of the right to strike by employees of any employer engaged in the state of Wisconsin in the production, harvesting or initial off-farm processing of any farm or dairy product produced in this state would tend to cause the destruction or serious deterioration of such product, the employees shall give to the commission at least 10 days' notice of their intention to strike and the commission shall immediately notify the employer of the receipt of such notice. Upon receipt of such notice, the commission shall take immediate steps to effect mediation, if possible. In the event of the failure of the efforts to mediate, the commission shall endeavor to induce the parties to arbitrate the controversy.
