Teachers from north suburban school District 46 are now on strike after failing to reach a deal with the school board by the midnight deadline.
As a result, the more than 300 teachers will hit the picket line Wednesday morning.
Nearly 4,000 elementary and middle school students will not have class Wednesday.
The teachers had been working without a contract since July.
Salary remained the big sticking point in the final hours of talks.
The district includes eight schools in Grayslake, third lake, Hainesville, Round Lake, Round Lake Beach, Round Lake Park and Lake Villa.
