CHICAGO (AP) - Negotiators for Chicago's teachers union and school board planned to resume tense contract talks at 11 a.m. Sunday after reporting some progress on Saturday.
The teachers have set a midnight Sunday deadline to call off the city's first teachers' strike in 25 years. Pay raises and job security are among their top concerns.
A strike would cause massive disruptions in the nation's third-largest school district.
Board president David Vitale emerged from Saturday's talks saying the two sides were "very close." He says the board presented a new proposal that "moved dramatically on almost all of the issues."
Union President Karen Lewis calls it an "improved" offer that still needs work.
The union set up what it called a strike headquarters on Saturday to distribute picket signs and T-shirts.
