I had my review with my supervisor last week which went extremely well. She was hinting at the idea that she sees my position different that what it is on paper because of the work that I actually do and not just what my job description says. She couldn't be specific but she kept referring to other people in the department and they are a higher classification. I know that I do the same type of work as them, if not more. I know she couldn't say much because are department may have to endure cuts (hopefully we don't) but we are not sure which areas just yet.
Anyways, no matter what, it's really nice to know that she seems me as extremely important to the department and appreciative of the work that I do.
