After failing to reach an agreement with Chicago Public Schools over reopening conditions this week, the Chicago Teachers Union has told its members to not return to in-person work and to work from home Wednesday. Additionally, the Chicago Teachers Union has told members to prepare for a strike on Thursday if city official decide to respond by banning remote teaching.
