Shady dealings of Job posting of my Current Job?

I found a posting of my current job during my college newsletter that is turing my current title into a full-time position. I have heard nothing about this nor have my co-workers who have ths same part-time position as me. I have no desire to work here full-time, but i need the references for future employment. What should i do? Do you think there is a chance i am getting fired? Should I quit beforehand?
