I said this is another thread, but I'll reiterate it here:
First, kids don't just go to school by themselves. There are teachers, support staff, and admin that might be immunocompromised OR have families at home that have health conditions that make them susceptible to the virus. And Kentucky's teacher workforce is OLD, not robust and young. On top of that, some districts are refusing to make accommodations for these teachers. Every time my county has opened its schools there's been a surge. Now correlation is not causation, I know, but this happened three times.
Second, even if we went back to in-person I can tell you from what my wife tells me that school is not "the way it was." Social distancing is enforced (to what degree it can) and from what I've been told most kids are mask compliant. However, there is no group work, no small discussions, no walking around the rooms, etc. It is all simply "sit and get" instruction. On top of that, teachers are having to do two jobs this year for the price of one to supervise online and in-person students. Ridiculous request if you ask me, but districts aren't paying the money to handle the requests from parents for options. I would not be shocked if we see a lot of resignations and retirements at winter break or after this school year because the burnout is real. I shudder to think what that could do for the state because teachers are not graduating in large numbers like they were a decade or two ago from our state colleges.
And finally, if you do open up and teachers have to quarantine, who are you going to put in a classroom? From all the news I've been following on this, districts everywhere are struggling to get substitutes because they tend to be retired teachers or old. Well, guess what? Those people aren't subbing this year because of the health risks. So when you get teachers, admin, secretaries, bus drivers, cafeteria workers, etc. calling in sick or having to quarantine by order of the local health department you can't replace them. You can't run a school without personnel. One of our neighboring counties has had to shut twice for this very issue. Another had to terminate bus service for three weeks until they got enough drivers again. Now, schools could help this if they loosened some of their sub requirements but I believe the state DOE sets those so its been a hindrance.
This time period sucks for teachers, students, and parents. No getting around it. But there are a host of reasons why these reopening plans aren't going well.
