My mother's a teacher out here in Minnesota.
We've been in far worse shape than you guys out east.
Had my mom been forced to return to school, even in a hybrid model, she would've quit. She's high risk, and even if she wasn't, didn't want to not see her daughter, brother-in-law, and nephew for who knows how long.
Thankfully, a fairly substantial portion of her district's parents wanted a 100% distance option, and her school was able to accommodate her. She's one of 3 2nd grade teachers that are teaching full distance classes. Each grade level has at least 2.
It's a MASSIVE amount of work, far more than she did in classroom (and she was already doing 60 hour weeks in classroom). I'd guess she's putting in 70 hours a week. That's with splitting some work load with her fellow second grade teachers. She has taken just one full day not doing anything since the school year started, and that was last week.
Certainly not an ideal scenario, but things are going far better than in the spring. Everyone has the right expectations and the planning and structure is far better.
On another note... It's snowing pretty hard here in the Twin Cities. We're going end up with 4 inches by tonight... On October 20. Absurd. I didn't even get all of the leaves raked.
