CHICAGO (CBS) — Striking teachers in Grayslake Elementary District 46 and representatives of the school board are scheduled to meet with a federal mediator on Thursday.

The two sides met for eight hours Tuesday night, before teachers walked off the job yesterday morning.

More than 300 teachers had been working without a contract since last July 1.

Meanwhile, teachers in West Chicago District 33 have voted to set a strike date.

They’ve been working without a contract for more than a year.

The school board announced last week that it will impose its version of a contract on Feb. 21.
