Millions of people still have to interact every day for work in non-essential roles as their employers won’t allow them to work from home or furlough. Thousands of kids have to go to school at the moment who didn’t have to in the first lockdown - more unnecessary mixing.
I’ve stopped working (self employed), not because I have to, but because otherwise my 6 yr old daughter would have to be on Netflix all day by herself as her mum (the bigger earner in our household) wouldn’t get a moment away from her laptop to parent. If I hadn’t cancelled my work, I do get the impression I could have tried to get daughter in school if I pushed and mixing with lots of kids. School is at capacity and they’ve asked some parents to reconsider.
