School is back in session Wednesday for about 4,000 students in north suburban Highland Park.
The District 112 school board and the North Shore Education Association reached a tentative deal early Wednesday, a day after teachers went on strike.
Teachers made the announcement just after 5 a.m. on the union's Facebook page after a 17-hour marathon negotiation session.
"We would like to thank everyone for their support over the past 24 hours. We are happy to report that the NSEA and Board of Education have reached a tentative agreement. Details will be shared with members at a future time. School will be back in session TODAY."
Talks started at noon Tuesday while teachers walked the picket lines calling for improvements in salary, benefits and reimbursement for continuing education.
It's not clear how they came to the deal or what the deal entails after both sides indicated Tuesday they were very far apart.
