The Chicago Teachers Union has filed an unfair labor practice complaint against the school district to block any more elementary schools from signing waivers and lengthening their school days.

The union accuses the governing board of the Chicago Public Schools of “unfair labor practices” and of “coercing” union members at schools to sign the waivers, which allow them to opt out of the existing teachers contract.
