Lots of good points being made here....... I worked in LTC years ago and here is my two cents:
1) One of the biggest concerns of the RN's I worked with was the fact that they were often working in a supervisory position as a unit manager/possibly expected to supervise the entire facility on weekends and nights, AND quite often had to take an assigment of patients if we were short-staffed (which was often!!)....very frustrating for them.
2) Another concern, which was also mentioned above, was the ratio. 25 patients to one nurse was considered an "easy" assignment. And I don't think acuity is as low in LTC as many people seem to think it is! I can't emphasize this enough. I can't tell you how many great RN's I worked with for a very short period of time; the number of patients assigned to one nurse was simply too high, and assignments were just not safe or sensible.
I never heard complaints about rate of pay, though, except in the form of "No amount of money in the world is worth what I have to deal with everyday." But that sentiment isn't exclusive to RN's, or to LTC, is it?
I don't know if either of these concerns apply to your particular facility, but I hope the the information helps. Good luck in your search.
