Your question: What if my boss makes me do something I think is pointless and I don't want to do?
My answer: You either do it or lose your job. Seriously. You can fight all you want, but in the end you know who's going to win: they are. Recently our bosses decided they wanted everyone in the hospital to provide human resources with a high school diploma. So I, for example, have been working at Shoreline for 15 years, and now all of a sudden I can't work unless I show my diploma? It makes no sense. I have absolutely no idea where my diploma is. But, I have no choice but to go out of my way to find one. The alternative is to get a job where the bosses do things that make sense.
There are certain things we as RT have no control over: we just have to deal with them. So how do you control the uncontrollable? You don't. The truth is, in the real world, you lose every day. They don't tell you that when you're a kid.
