Gosh they have got you over a barrel!
Dont be soft or fooled into thinking you have to bend over backwards to accommodate the needs of the SWs
Do you realise you are saving them hundreds of thousands a pounds a year by looking after these children
You should be clear that you want to remain in your role and ask how they can assist with that given the current challenges you are facing
As a pp said they can certainly assist with contact centre drop offs etc and also you can ask for meetings to be later in the day and it’s totally fine to say you need them to be on your day off
If they can sense you are weak or clueless they will not bend
Also as the children have managed well with you working this long they’ll be just fine if you continue to do so
you say you are not able to hire a nanny, well you could probably do with a mothers help/housekeeper
someone to assist with cleaning, chores, drop offs etc
theres plenty agencies who will offer these staff with Enhanced crb checks
