Chicago Public Schools pre-K and cluster teachers and staff who don't have an accommodation will be required to report to classrooms Monday. The district has maintained that it presented its "last, best, and final offer" on Friday. Pre-K and cluster teachers and staff who fail to report will be deemed absent without leave, and access to CPS systems will be terminated at the close of business Monday.
