A coalition of groups including ONE Northside, SEIU Healthcare and the Jane Addams Senior Caucus will hold a rally outside the Chicago Board of Trade building at 11 a.m. Monday to “demand that the Illinois State Legislature move forward with proposals that would raise more than $2 billion dollars each year, by ending tax breaks for large corporations and ultra-wealthy individuals” — including by repealing a tax break for the Chicago Mercantile Exchange.
