Just one after classes were back in session for the 2025-26 school year in suburban Naperville, District 203 Superintendent Dan Bridges sent a message to parents, advising families of a possible teachers strike after months-long contract negotiations stalled.

After three bargaining sessions this week failed to produce a new contract, union officials announced Thursday night that Naperville School District 203 teachers will go on strike Tuesday.

Teachers in Naperville Community Unit School District 203 have set an official strike date. The date is next Tuesday, Aug. 26. The union said the school district's latest offer is actually a major step backward. CBS News Chicago is told there is a bargaining session set for Friday, but that session is the last scheduled.
