I recently went for an interview for a per diem position in my specialty. I chose this specific hospital because it is the closest to my house. The hospital is very much similar to where I work now fulltime. I was interested in picking up a per diem job because of concerns in regards to cuts in hours when our census is low. I just discovered during the interview that they pay based on years of experience and they don't pay more for prn. This wouldn't be so bad, but the pay is slightly less than what I make at my fulltime job and requires 3 shifts a month, 1-weekend shift, 1 winter holiday, and 1 summer holiday. At this point, I'm not sure if it is worth it due to the low pay....please advise. Should I try and negotiate pay? They have a union fyi. And should i decline the offer should I mention specifics in regards to why?
