I know people who take jobs like that after being SW's, they are on a similar pay, but have a lot less to do.
My DD is a residential MH Manager.
She has to run the residential house, including Staff Rotas/issues. Recruit/interview/sort out Bank Staff/ML etc.
Work within her budget. Try to come up with new initiatives etc. Sort days out/lesuire etc.
Sort the Medicine delivery/administration, go to MAPPA meetings/Poluce/SW's.
Oversee the residents Care/meal pkans/money management etc.
And be hands on in the house. Be on call 24/7.
All on around 21k.
You'd be surprised what Care Assistants and Support Assistants have to do for about 50p above Min Wage. I know good care staff who have become cleaners because of the workload.
Neverunderfed, perhaps not on paper, but often what the person brings to the role etc isnt common, unfortunately they aren't valued.
At one time when degree level education wasn't the norm, we justified the wage discrepancies, but I don't think it's a valid argument these day, for a lot of roles
Surgery and Doctors, is very different. But outside of Senior Health Care, there isn't a real skills shortage to justify the pay gap.
