I don't class my cleaner as "below me". I regard her as a service provider with whom I've entered into a business contract (on terms rather favourable to her, in fact, and that's perfectly fine as well as deliberate on my part), and I expect her to keep up her end of the bargain.
Now, as stated before, I love my current cleaner. But, again, this is as a service provider. She's not a mate of mine. She renders services to me in exchange for compensation on my part.
I don't see her in much of a different light than the one in which I think my clients see me: someone being paid money in exchange for a promise to fulfill a contractually defined set of tasks.
Now, ... will my own happy clients introduce me to their own bosses and will this enable me to make more business? Yes, clearly, if I don't suck balls at my job! Will I do the same for a good and trusted cleaner? Sure! Does this include said cleaner being invited to a house party that includes a number of potential new clients? Well, most certainly (not currently, mind, thanks to COVID)!
But, again: it's a business relationship. If we happen to get along like a house on fire: so be it (and, yes, friendships do make business more complicated). If we don't: so what, so long as both of us fulfil our mutual obligations?
