Make the most of my job and I am punished?

I work at a small town library full time, processing books while I obtain my Masters in Library Science. I have moved up to this position from Reference istant in the course of a year. I work full time and make $22,600/yr and am 32 years old (married.) While I worked Reference I was encouraged to start a club at the library, and I had, a yr ago. It is arguably the most successful club at the library. I also have organized several programs. I enjoy creating and doing new things that aren't in my job description, but recently I have felt unappreciated. Every time I organize and plan something well, the community applauds it and my supervisors are displeased. Just yesterday I was told I had to cancel my club meeting here after a year! My response was to tell my supervsiors that I will not be doing anything extra in the future. If I am not getting paid extra and they discourage me from planning and executing successful programs, why should I waste my time? What do you think?
