I'm not sure, but I would change your title to "should I have a minor," that way it doesn't sound....slightly inappropriate....
Doing a minor is NOT more work, if you integrate it into your coursework. It's favored by higher education (if you want a masters or phd) and its favored by employers because it shows you can branch out.
Depends on what your major is. Pick the minor that is the most valuable for later, and that you enjoy the most. Look at the classes offered. I'm a history major, but I study the middle east, so I wanted to learn a middle eastern language. Thus, I have a modern Hebrew minor.
Oh, I could study everything else too. But, what is TOP?
Don't let work scare you off. It pays off, really.
