Not trying to spark another debate on whether or not they should close, just thinking of the practicalities, if they shut from, say, April til the new academic year in August/September? We are lucky as my job is PT and mostly WFH anyway, DH can WFH if need be and is from now on. So we can work around each other (though not necessarily too productively as our DC are young primary and we don't have much space). But if that wasn't the case we have no family who could help out and the grandparents are either still of working age themselves (one an NHS worker) or 70+ with health conditions.
