Teachers within a network of charter schools have decided to strike due to issues related to pay, class sizes, protecting undocumented students, and much more. This is the first time in U.S. history that charter school teachers have gone out on strike. More than 500 teachers from 15 charter schools are participating in the strike, most of whom are represented by the Chicago Teachers Union. The teachers intend to stay out on strike until their employer presents them with a more reasonable contract, according to the union’s president.
