According to the union, CTU and CPS signed an agreement that includes the district providing buses for field trips so students and teachers can attend a May Day rally in Union Park. The union said the agreement also include a pledge from CPS that there will be no retaliation against any staff or students who participate in May Day, and that the district agreed that future May Days that fall during the work week be teacher-directed professional development days “so that we all have clarity for the years to come.”
