That would still affect the staffing of hospitals and the rest I mentioned, and more. You could ask those that have alternative arrangements to keep their children off I suppose, those with grandparents or non-working friends who might step in. You could try asking all those with non-essential work to stay off, and keep their children off too, but I suspect the list of people that consider their jobs essential is actually quite large. And then a lot of people couldn't or wouldn't do without wages for very long, so that would have to be considered too. It might not be the sort of thing that's usually said, but I think we have to trust the government, advisers and civil service on this, it's just too complicated for individuals to come up with solutions off the top of their heads. Especially me.
