RN for 24 years
2 jobs in Labor/delivery/ post partum lasting a total of 15 years (we moved out of state so I had to get that other job). Left on good terms.
1 year in LTC (God bless all you LTC nurses; I could not hack it). Left on good terms
1 very short stint in oncology (outpatient) where I did not last as I did not fit in at all. I was not learning fast enough, so.... Left on good terms.
10 years in Dialysis (I don't love it or hate it, just look forward to retirement one day).
If you do that math, you see there is overlap (or there would be too many years, LOL). I did do PRN in one while I did full time in another.
