DSs school has plans for cover teachers or TAs in a class for behaviour control with self isolating teachers joining by Zoom to direct learning , obviously not if the teacher is actually I'll though
I've been really impressed with their planning. They have two trial days planned where all children in 3 years will trial working at home with a full timetable of live lessons but done remotely. Years 11 and 13 are not doing this as they will be prioritised to come in at all costs. The trial is to make sure they iron out any problems with tech and non engagement in advance in case they have to quickly switch to online or blended for some years .
They are also actively fundraising for basic laptops for the children who don't have one they can access exclusively during the day.
It won't be perfect but they have really given it a lot of thought and planning . I am very impressed
