Deadline Tonight to Avoid Chicago Teachers' Strike

Negotiations continue

Negotiators for Chicago's teachers union and school board plan 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.
