@Tanith. I agree with you that the government "recommending" parents don't send their children (while paying full fees) is nonsense. Either nurseries need to stay open or they need to close and refund parents.
My own perspective is that I don't want nurseries to shut. Partly because I want to keep my job and if they do, I will have to take leave which will probably be unpaid. Partly because I believe my son's setting is safe - it's fully outdoors at the moment and they have a large space for the number of children. Some nurseries have done a fantastic job of minimising risks and I think those nurseries that can operate safely should continue to do so rather than penalising all nurseries. A nursery which keep children outdoors for the whole day in the open air has a completely different risk profile from one with a large number of children crammed in a crowded inside space.
However, if the figures on transmission support closing nurseries, I will accept that and the consequences for our family and use the rebate on fees to pay for me to take leave.
I do think staff need to be protected (especially vulnerable staff), but I don't think parents can do much about that. It is the responsibility of nursery owners to provide a safe working environment for their staff. If they really believe that to be impossible, they (not parents) need to lobby the government much more vigorously to close nurseries and provide financial support or take the initiative and place their vulnerable staff on leave.
Just like the buck stops with parents in terms of caring for our children, the buck stops with nursery owners and staff in terms of ensuring safe working practices and making sure vulnerable staff are protected. Asking parents voluntarily not to send their children is not a good solution.
