Rainbowunicat DS's head teacher has said she expects the school to stay open during the school holidays. Obviously there is a suggestion somewhere that they will need to because key workers who normally would be on holiday now no longer will be, so key workers will need childcare assistance as it won't be available privately.
That also suggests a possible cancellation of leave for key workers - particularly NHS workers - being a possibility.
In Italy all leave for medics has been cancelled so I suspect its something that's on the cards as a possibility here too.
Nothing firm but you'd have to assume that's part of emergency planning. The NHS can't have loads of workers off for Easter if we are just going into a peak of demand which is what the projections suggest will be the case.
