Negotiators trying to bring an end to the Chicago teachers' strike say the most recent talks made substantial progress and suggested that classes could resume Friday.
The bargaining ended shortly before midnight Wednesday. Chicago Teachers Union President Karen Lewis said the sides had definitely come closer together. She said the strike would continue Thursday but added: "Let's hope for Friday."
School Board President David Vitale was also more positive. He agreed that negotiators had made progress, and he was hopeful they could come to a deal in time for students to return to class on Friday.
Chicago's teachers went on strike Monday for the first time in 25 years.
