Cook County Board President Toni Preckwinkle and her finance team released the county’s Fiscal Year 2018 preliminary forecast Thursday. The mid-year projection of year-end revenues and expenses for the rest of FY17 is a look ahead to the budget that will be introduced in October. While President Preckwinkle promised no new taxes, it’s likely union employees in the county will face tougher negotiations as collective bargaining agreements are hashed out.
