I realize your desire for change from the ER. I'm sure you have seen enough to last you a lifetime.
I just recently resigned my position as DON in a 43 bed LTC facility to work as a staff nurse at my local hospital. My reasons were many. I worked as an aide, LPN, and RN in LTC (different facilities and all three shifts) and I found as DON, I really missed actually seeing residents and being their nurse. Instead of nursing patients, I was nursing paperwork. QA's, incident report tracking, staffing trends, MDS stuff, chart review, staff evaluations, scheduling (my least favorite part), skin reports, pain control trending, care and quality issues, hiring and firing staff, training, audits, and meetings, meetings, meetings.
I just wasn't cut out for it. I was expected to cover shifts when a nurse was sick, on vacation, or was off for disciplinary reasons, and if CNA's called in, I was the one expected to find replacement personell. In a small facility, there aren't a whole lot of people to help you with your job and you wear a lot of hats.
Having supportive, openly communicating management staff speaks volumes. I had an administrator that was completely unorganized and work was almost more difficult with them there. Thankfully I had an office manager that was also an RN that helped me significantly.
And about the salary, it may be impressive when you accept the job, then you figure how many hours you work during the week (and I was on call 24/7 by phone and worked 45-60 hours a week), you realize that no salary can compensate you for the stress level.
I know that it is not like this everywhere, but beware. The grass is not always greener on the other side.
