Let me spell this out.
If we do not run this service, we will lose perhaps 20% of our workforce due to inability to find childcare.
If we do run this service, those people who are using it as childcare will become infected within a month. If 20% of the healthcare workers are infected, as in Lombardy (and remember, this figure is already over a week old), then there will be at least one contagious child in every class. And we are proposing mixing everyone else's children with them, with no PPE and no distancing measures.
What this will mean is that those HCW children will then infect the teachers, the children of the shopworkers. These people will increase load on the NHS. The shopworkers, the delivery staff, will all return to work, spreading the virus assymptomatically, INCREASING infection in these groups.
This is a BAD idea. It will not aid the country, it will actively encourage spread.
The government is making the WRONG decision, at the WRONG time, as it has all the way through thsi.
