HIGHLAND PARK, Ill. — A teachers' strike in suburban Chicago is over after leaving more than 4,000 students out of class for just one day.

Negotiators in North Shore School District 112 reached a tentative agreement early Wednesday to end the strike. That means classes are back on for students in Highland Park and Highwood. The district's students range from pre-kindergarten through eighth grade.

Teachers began walking the picket line Tuesday after talks failed to come up with a deal. The issues included retirement benefits, salary and compensation for graduate work.
