They might be ordered to work.
Oh ,yeah. But this isn't China . The worse they can do is threaten them with the loss of their jobs.
I guess , even if daycare centres, nurseries or schools are shut ,something will have to be arranged. America -and the world- might wish to pay an enormous cost to keep senior citizens alive for a few more years, but there will still be a minimum of infant welfare here.
And we're not talking about just the children of doctors and nurses here, but also those of ambulance staff, paramedics, lab technicians, managers, administrative staff, maintenance staff and cleaners too .
Also, these health service employees,if they catch the virus, won't be able do their jobs and have to quarantine themselves at home. All this might well happen under a backdrop of a large influx of emergency Coronavirus patients to hospital wards..
So ,you've potentially got a serious situation here. Sure. health services can hire more people and try and force their employees to work overtime. Still ,if hospitals are overwhelmed , in the next few months people will be dying,who would otherwise have survived - and not just from COVID-19.
