Classes were canceled for about 300,000 students in
Chicago for an eighth day on Monday as the teachers' union and public school district failed over the weekend to resolve a deadlock in contract talks over class sizes, support staff levels and pay.
Each side blamed the other for the impasse in the third-largest U.S. school district, where the strike began on Oct. 17, and the union, which represents the city's 25,000 teachers, has been without a contract since July 1.
The strike is the latest in a wave of work stoppages in U.S. school districts in which demands for school resources have superseded calls for higher salaries and benefits.
