I wish I was surprised, but I'm not. (Warning, leftie anti-small-state political rant.) There's a type of neoliberal politics, introduced to this country by Thatcher, and eagerly pursued by our current government, that's 'small state', mainly dismantling public services by 'defund, demoralise, privatise'. Of course, that only means privatising the profitable bits - just abandon the rest and let philanthropy and 'natural selection' sort it.
I'm amazed anyone can still recruit social workers. I have my suspicion that what in America is called the Great Resignation, where a shortage of some sorts of workers is leading to loads of workers retiring early, leading to more shortages and workers being pickier.
Here, we have doctors and nurses quitting. Some of you will have read or maybe seen the documentary about Operose-owned GP practices, which are massively understaffed, with lots of the GPs replaced by Physicians Assistants, and incoming correspondance dealt with by non-clinical staff, who decide whether to file or pass on to a GP or PA. Etc., etc.
So why would anyone want to work in public service in any D,D,P role?
