I estimate that DS1's primary teacher was spending about 30 mins per day setting cover work remote learning. That's pretty generous as an estimate. We got a 20 min phone call for his SEN review. There was one week on the key worker rota. Minimal marking if any.
DS2's teacher put more time and effort into setting work and sending reources and did a weekly zoom quiz.
If my teaching workload had been that light, I'd still be a teacher! No double marking, diferentiation, data analysis, observations, seating plans with key information for 12 classes or team meetings. Admittedly setting cover work always was a ballache, but that's a considerable easing of workload.
Now all hands are on deck to teach 50% of the school, the deputy is setting a weekly school wide project.
One phone call in 10 weeks between 2 DCs, one with several SENs... I doubt the phones have been that busy.
It's a far cry from when my daily teaching routine was 6-7:30, 8:30-5:35, 9-12.
I know different teachers have varied even within schools let alone from school to school, but some have clearly had a much lighter load than usual.
