3 hours of cleaning is 3 hours you were not doing the job you were supposed to be doing in those hours.
If the new normal involves this level of cleaning all the time, then it also needs additional staff so children still get the level of care and education they were before.
The new normal can't be lower standards for children's education because staff are cleaning instead of interacting with them.
The rules create extra labour, therefore the government needs to provide extra funds to cover this. Not expect schools/nurseries to just juggle, because staff can't do 2 jobs at the same time and most are already using all their budget.
An EY educator cleaning is not doing the job they are being paid to do. Who's doing that in those EY hours instead, or are we expected to think "no one, the kids are left without adequate staff attention" is acceptable now?
