The Chicago Paid Sick Leave Ordinance and the Cook County Earned Sick Leave Ordinance took effect in July 2017. The language of each ordinance largely mirrors the other, and where an employer falls under the jurisdiction of both, the Cook County Interpretative and Procedural Rules provide that the Cook County Commission on Human Rights (the enforcement arm of Cook County) will defer to the jurisdiction of the City of Chicago’s Department of Business Affairs and Consumer Protection (the enforcement arm of the City of Chicago). Effective July 1, 2020, the Chicago Paid Sick Leave Ordinance is amended in a significant way.
