I assumed live-in akin to those who work at a family home not an actual care home, sorry.
Yeah, I've known a lot who have done this sort of work and it's been fairly brutal in terms of par/reward, which is sad really. Probably earn more working as an HCA in a hospital and more-or-less choose when she wants to work too!
The benefit of her job for us is that she does 38 hours in 2 days, (14 hour shift, paid 10 hour sleep, followed by another 14 hour shift) It isn't full on all the time currently either, the kids have to go to school during the day and as I said above they are older, there is another house she was placed at for a while and they have younger children, 1 of whom has at least 3/4 physical interventions a week, so that house is a lot more full on.
I have gone fully self employed so I can work my hours around her (we have 2 young children)
with regards to my OP, the only worry for my partner is that its a very female dominated environment and they can all turn on each other very quickly, one of the seniors is largely disliked by everyone because of her attitude, at the start of my partner's placement there she got on with this particular senior, then one small thing happened and now she makes my partner's life uncomfortable whilst on shift.
When the manager that was sacked was under investigation, everyone was backstabbing and covering thair own backsides, her worry is that if she goes above her manager it will make her "bad guy", she is currently quiet good friends with the manager and they get on, so she enjoys working there, but if everyone ended up being like the senior she would be miserable, so I think she is reluctant to go higher so as not to upset the apple cart too much.
