Not all obviously, but I worked as a temp in one recently. Full-time staff worked from 8-6 usually with only a 30 minute break, 5 days a week. No school holidays too as it’s open all year round.
There’s a lot of paperwork involved, it’s likely for Ofsted, seems like it’s all about documenting everything and ticking boxes.
It’s a very demanding job and many of them are paid minimum wage or slightly over. I’m sure they do it as they love children, but once again makes me realise how jobs that involve looking after people are so underpaid and undervalued.
