A new law passed last year makes it more difficult for the Chicago Teachers Union to strike. It provides that:
■ If the parties can’t agree, they must present their sides over 75 days to a neutral fact-finder — a process that’s already begun. The fact-finder’s recommendation is due July 16. If both parties don’t accept it by July 31, a 30-day no-strike window opens. The earliest the CTU could strike is somewhere between Aug. 17 and Aug. 31. Classes for kids in year-round schools start Aug. 13; classes for most kids starts Sept. 4.
■ 75 percent of all CTU members must authorize a strike, up from a simple majority of all who vote on any strike proposal. However, the union’s House of Delegates must then set the strike date if a deal is not reached.
