Ald. John Arena, 45th , is the chief sponsor of the latest version of what is being called the Chicago Fair Workweek Ordinance. Twenty-nine of his colleagues have signed on so far. This is the body of aldermen, remember, who squealed and complained several years ago when the legislative inspector general asked them to turn over time sheets for staff in their offices. Many aldermen didn’t even keep time records or refused to produce them. But now they want to intervene in how private companies schedule their workers.
