One of the things that you need to consider when you talk about schools going back so the children can get back to normality is that the school may not be normal. In order for a school to function as normal you need the appropriate members of staff in. If some of those cannot return because they are still shielding then school cannot function ‘as normal’.
As an example, I work in a small rural primary school. In the last week before lockdown, of the 16 or so staff members who normally work (and I include in that the school cook, secretary, and lunchtime staff) we had six in. Of those who were off, three were off because of coughs that they or someone else in their family had, so we would expect them back. We would still be seven staff members down, all of them with underlying health issues.
We cannot function ‘as normal’ missing that many people. We don’t have enough teachers to go round, nor enough TAs, especially with the one to one support missing for the children who need it. And we may not have enough adults to safely supervise all the children at lunchtime and still get the things done in the break that we need to get done to prepare for afternoon school. We operated like that in the last week, no adults had any breaks, we were lucky in that quite a few parents chose not to send children in so we had fewer children than normal but I was, for example, looking after nursery, reception, Year 1 and Year 2 altogether so the nursery teacher could cook lunch. It was fine. But it is not normal. I’m a TA, not a teacher. We didn’t have enough teachers in for everyone.
We do need to include this in the discussion. If you think that some people will still need to shield but because children aren’t badly affected they can go back, and therefore they will go back to school exactly as it was, you need to remember that some of those shielding adults will be school staff. Not just teachers but all the other people who make a school function, and remember that school will not be normal again until those people can get back to work too.
