Are they doing any mitigations at all? Any distance or masking, extra ventilation, air cleaners, anything to make it safer at all? How "just dumped" is it?
For us, they're barely back in school at all. Just 50% and only every other week. That's 25% of kids in school any week. They still close the school on Wednesday to "deep clean", and there is still to much surface worry and not enough ventilation focus. The high school is switching classes, but even so kids may end up in a room without the teacher who's remote. It's a simultaneous model, one teacher for both in the room and remote. In the middle school, its even worse. They mostly don't switch rooms at all. So, across 4 classes in a day, the teacher in the room may be for 1 of them. All the kids aren't even in the same class at the same time. They're all on zoom from the room to wherever. When it is the teacher in the room, they have to mute the zoom to prevent echo and then cannot hear any classmates from zoom. They switch for gym, and then do zoom class with the remote people. They switch for band half the time, but don't really play, for obvious exhalation reasons. Apparently, they cannot move the band outside to create enough distance for "reasons". Yesterday's school board meeting it became obvious that we're lucky for even this horrible disaster. Somehow being almost last to return we cannot learn from anyone else and it's not possible to do any better. That they didn't make any progress for the last 9 months on returning because all the focus was on remote support. One of my kids middle school friends has health instead of gym this quarter and isn't in band, they switched back to full remote because the in building was so much worse with quite literally no extra value for the effort.
There has to be some middle ground. Something in between "just go back and pretend it's all fine" and "returning is so bad, you'll want to stay remote".
