CHICAGO (AP) – Chicago’s teachers agreed Tuesday to return to the classroom after more than a week on the picket lines, ending a spiteful stalemate with Mayor Rahm Emanuel over teacher evaluations and job security, two issues at the heart of efforts to reform the nation’s public schools.

Union delegates voted overwhelmingly to suspend the strike after discussing a proposed contract settlement that had been on the table for days. Classes were to resume Wednesday.

Jubilant delegates poured out of a South Side union hall singing “solidarity forever,” cheering, honking horns and yelling, “We’re going back.”
