“We are fighting for our students’ safety, their family’s safety, our safety and believe it or not, your safety your brothers’ and sisters’ safety of this union,” said CTU member Deanna Myron of Curie High School.

CTU said the district needs to make more testing available, have a clearer mask policy and let teachers work from home if they choose to, especially when they or their family have fragile medical conditions.

CPS warned any teachers who don’t show up for in-classroom instruction could face discipline.
