Complicated power relationships in a work context

Someone contracting with you to do something is like a boss, but it’s a different relationship; such a person is a client and a client is more like a customer. It’s your job to do what the customer wants but the customer isn’t in charge of the business. Or maybe I’m off base. Of course, if the disabled woman didn’t hire and can’t fire this person, the person’s working for the parents, then, aren’t they?
I think the power relationships between assistants/PAs/whatever and folks with disabilities are a lot more complicated than that.
Even with a direct hire, it’s more complicated than other types of employment. For instance, hiring someone to write a webpage for you is really different than hiring someone to do things you need in order to survive.
Especially, given that when people murder folks who are disabled enough to need extensive care, they often get away with it.
And there are all kinds of complications I don’t understand well.
I don’t know more to say about this, though. Do any of y’all?
