The Cook County Board approved a sweeping paid sick leave mandate yesterday, despite a divided party vote, dueling State’s Attorney memos on legality and some business opposition. Two commissioners doubled down on pro-worker reforms by introducing a mirror ordinance to Chicago’s minimum wage requirements that would bring the county up to a $13 per hour wage by the summer of 2019. A new tax on Uber and Lyft rides, extra procurement disclosure requirements, and a sales and property tax freeze were also introduced.
