I just don't like that workplace language - even if I was the POTUS, I don't think I'd say it.
I find it very bothersome when middle managers (and even higher) talk this possessive way - "the woman who works for me" or "I pay you to do X"...
Unless you really ARE paying someone to help you, they don't work for YOU. They work for the institution, the company, the big guy - but not for YOU.
You may be the lucky stiff who delegates and writes performance reviews. But they don't work for YOU. Get over yourself already.
