Teachers at four charter schools in Chicago are on strike again, after bargaining did not result in a satisfactory contract. Chicago educators have been negotiating for many months, and just recently rejected a new contract proposal which means that they are going back to the picket line. The strike has negatively impacted 2,200 students by disrupting classes. While there are substitute teachers, the school is largely understaffed and not entirely operational.
