Weird Email from University

I received what I think is an odd email from the university I work for. It was asking if I work for other universities, how long I have been teaching in higher education, and what (if any) publications I have. This was out of the blue after I have been teaching for them for over a year.

I thought this odd for several reasons. First since I am a contract worker I do not think that it is any of their business if I work for other universities. If they don't want me to teach anywhere else they can give me a long term contract where I am guaranteed classes or make me full time. Second, since they as a university do not pay me to do research, or pay for me to go to conferences why would they expect me to publish? As I understand it very few adjuncts publish for this very reason. (Not to mention the fact that being published, which I am, has not had any positive effect on my getting classes on a more regular basis from this university.)

I find that universities wanting it both ways, having the credentials of a full time professor, but don't expect the benefits of a full time professor, irritating.
