No lemongrove I don't claim to be the font of all knowledge on teaching or schools. I know very little about the organisation of primary schools, despite having had children go through them.
However, I do know more than a little about the logistics of secondary schools. In a former life I was a middle manager in a large comprehensive school and was responsible for organising things like timetabling, rooming, staffing, cover for absent staff, etc. It was my job, so I can see issues which even some in schools couldn't see.
I wouldn't dream of telling anybody how to organise any other workplace, so I do take exception when somebody persists in telling me how magical solutions could be found, when I know very well what's possible and what the risks are.
I've already given some suggestions and said what I think will happen. I'm still in touch with various senior staff working in secondary schools and I read what others, such as the DfE, unions, scientists, etc are writing.
I could be wrong. Maybe the government really will try and bluff it out. A lot could happen in the next three weeks.
