Can schools safely reopen without teachers vaccinated for COVID-19? Dr. Robert Citronberg with Advocate Aurora Health answers your COVID-19 questions. Twenty-five thousand Chicago Public School teachers will be asked whether the agreement struck between their union and the mayor is good enough for them to return to in-person learning via secret electronic ballot. "Our members have to read it, discuss, and ultimately, make a decision as to what is going to happen next," CTU President Jesse Sharkey said. If approved, students, teachers and staff will have a staggered return to their physical classrooms. Pre-K and Cluster students will return Thursday, K through fifth grade on March 1, and fifth through eighth grade on March 8.
