And unqualified substitutes showing movies to combined classes is a great way to learn?
There's clearly no easy answer.
There is one thing that everyone should be able to agree on. A teacher/student who is positive, with no or mild symptoms can certainly teach or attend class virtually while they cannot do that in person. Someone who is sicker couldn't do either.
At some point, that may be the tipping point that forces us virtual. It'll be the inability to staff classrooms and transportation.
Repeating my kids situation with 2 of 7 teachers out. Presumably, the in school class quality for the 5 classes is currently outweighing the substandard quality of the 2. Very dependent on if they have a sub or not, and if it's a real sub for that class vs just a warm body. I think they have a real one for 3 of 5 days this week for one of them and "study hall" for the last 2 days. Likewise, my other kid doesn't have enough gym teachers to conduct real gym class. Most of us probably agree that gym doesn't translate to virtual well, so this isn't a huge difference if it means better math and English in person.
There's been mixed feedback on changing the the plan to go virtual at 5% to "case by case". Some want virtual now, others never, others in the middle. I think the goal of "case by case" is to evaluate the impact of the 5% along with any tracing of where spread is really happening. To allow a nuanced approach instead of a hard line set at a level that many feel is to low. I don't know the right answer, no matter the choice, someone will be unhappy. Probably lots of someone.
For a more WDW focused version of this. Are we seeing staffing impacts at the parks? Things running at reduced capacity or some attractions closed for staffing issues? Anything where staff is being shifted from one function to another where possible to keep one item open while closing the other? That would be the equivalent park issue to the school staffing problems. I'm sure WDW generally has a larger over capacity staff pool than most schools do, so it would take longer to show an impact.
