As someone working in a school, it's a no.
Schools need to be open. The impact on children's mental health is appalling, the children with GCSEs and a levels in next 2 years will likely be fucked over big style if this year's fiasco is anything to go by, the safeguarding concerns it flags up are monumental.
Lovely happy families who can work from home, have a stay at home patent or older children that can self manage good quality school work are not the norm. The people struggling are the ones school need to be open to support, in addition to ongoing education that needs to be provided which home learning dies not adequately replace.
