I don't agree that the old council homes were better. My grandfather was in one and it was grim, I mean the staff seemed OK but it was very institutional with polished lino floors, no such thing as an en suite, no personal furniture in rooms, well they were shared anyway.
I have an elderly relative in one now, beautiful carpeted room, nice bed that doesn't look like a metal hospital bed, beautiful en suite, her own things round her e.g. TV, radio, chair, curtains and bedding.
I don't get the no career progression, you get senior carers and deputy managers and managers. They were presumably carers at first.
