I spoke to management today and just wanted some confirmation that I could still send DS in (they sent an email out saying they're happy to try and sort things for essential workers at this time).
They asked me what I do and then said no, they couldn't take DC as I'm not an essential worker 
I am, and if we go into lockdown our services are classed as essential and will continue to run. Is it really up to the nursery if they take DC or not, or are they discriminating? Yes of course they can set their own rules but not ones that discriminate surely.
I'm fuming and honestly don't know what I'll do
