Teachers, paraprofessionals and school clinicians in Chicago have been without a labor agreement since June of this year.

Following the inability of the Chicago Teachers Union (CTU) and the Chicago Public Schools (CPS) to reach an agreement over benefits, the role of standardized tests in teacher evaluations, and physical improvements to schools that teachers say are harming both teacher and student performance, the CTU has announced that a city-wide stirke will begin today - the first teachers strike in 25 years.

Pickets are expected at 675 schools and the Board of Education.

The following are remarks from CTU President Karen Lewis.
