Working Hard, Hardly Working

My job is getting harder and harder. I've been there for 2 years now and I find myself with more and more responsibilities. I mean, that's great and all, but now I get contacted for all kinds of things that I don't want to deal with. I just want to go to work, put my feet up and relax. Is that too much to ask for? A couple of months ago, I was asked by my boss to lead some major testing sessions. I seem to have taken over the design and management of our intranet site, and now I'm being volunteered to go to a union meeting to represent our department and explain what we do and how we're important to our profession. Some of these things are interesting, but like I said, I just want my easy job back.
