20 ILCS 1015/1c

The Department of Employment Security shall place itself in communication with large employers of labor, including municipal and other public authorities, and attempt to bring about such cooperation and coordination between them by the dovetailing of industries, by long time contracts, or otherwise, as will most effectually distribute and utilize the available supply of labor and keep it employed with the greatest possible constancy and regularity. The Department shall devise plans of operation with this object in view and shall seek to induce the organization of concerted movements in this direction. The Department shall also endeavor to enlist the aid of the federal government in extending these movements beyond the State.
