Chicago public school teachers will go on a one-day strike this Friday that may or may not be legal. Chicago Public Schools Chief Forrest Claypool joins “Chicago Tonight” to talk about the upcoming one-day teachers strike and what parents should do. 

Chicago Teachers Union President Karen Lewis said the newly approved April 1 walkout is not about contract negotiations with CPS. “If it were a contract strike, it would be illegal,” Lewis said to Eddie Arruza. “This is an unfair labor practice strike.”
