Chicago (ap) — Chicago teachers took to picket lines Friday in a one-day strike they said was aimed at getting lawmakers to adequately fund schools in the nation’s third-largest district.

The walkout closed schools for nearly 400,000 students, who had the option of spending the day at “contingency sites” Chicago Public Schools opened at churches, libraries and school buildings. Among those picketing outside Oscar DePriest Elementary School was special education teacher Brian Orlinsky, who said he hoped the walkout would be a wake-up call for Chicago Mayor Rahm Emanuel, Illinois Gov. Bruce Rauner and other lawmakers.

“There’s not enough textbooks,” the Spencer Technology Elementary School teacher said. “There’s not enough technology that’s up to date and that’s working.”

Friday’s actions also could foreshadow a longer strike over a new labor contract.
