I guess we have different interpretations of what happened in Chicago and elsewhere. In our school district the teachers’ actions diverged from a group focused on safety, regardless of one’s interpretation of the covid threat level. I used to be 100% behind the teachers when they were fighting for better pay. I’m sorry to say that they have lost my support. I should probably also say that I’m not generally anti-union. Workers have lost a lot of leverage since the 70’s.
