Having a horrible boss that uses their employee to do the work that this person doesn't want to do is actually extremely common. Unfortunately, corporate life can be awful sometimes. Is great to have a steady salary, benefits, PTO, even coffee at your disposal during your whole shift. But there is a horrible thing on the downside. Like having a boss who takes advantage of you to do things that he doesn't want to do, like the one from the story below.
Sometimes we feel as if we are exaggerating something that we feel. When you are a student, you tend to think that a teacher hates you, didn't you? Well, that also happens in corporate life. Is not uncommon to believe that your boss hates you. This could be true, and then you would have an awful boss. Or maybe you are exaggerating and thinking too much about someone who barely knows how you are. This dichotomy is actually what sometimes makes us not speak up during something unfair. The fear of making a big deal over something that was actually nothing.
My genuine advice for this kind of situation? If you feel like something unfair is happening and you are being taken advantage of by someone in a higher position than you. Reevaluate the situation, watch it from another angle. Make sure that is what's happening and not some kind of confusion. If you bring to HR a situation that is actually a misunderstanding (or could be seen as one), then you are putting your job on the line. But if you are sure, speak up. Maybe you are lucky like this person and can get it all figured out for the better.
