I know there's a separate topic. But please please consider that for far too many children in 21st century Britain, their free school dinner is the only proper meal they eat.
I have direct experience of this, from both sides. If schools are forced to close (either by the government or due to having no staff) then many thousands of children will go hungry. Others will also lose their safe haven, place to be themselves instead of a carer, escape from domestic abuse.
If you can, drop something off at your local food bank or shelter. Ring your council for places to donate. Be supportive of your schools - there is so much more going on inside those walls than exam grades.
