GRAYSLAKE, Ill. — Thousands of students in northern Illinois won't be in school after teachers went out on strike.

The strike beginning Wednesday involves about 4,000 elementary and middle school students in Community Consolidated School District 46, which serves Grayslake, Round Lake, Lake Villa and several other communities in suburban Chicago.

Superintendent Ellen Correll says negotiators failed to reach an agreement Tuesday. Jim Pergander of the Lake County Federation of Teachers says the talks stalled over pay.
