I have been working on a medical surgical unit for about six months now. Unfortunately, it isn't working. Frankly, I'm miserable there. I have thought long and hard about this for months and I have decided to pursue other career choices. I know that the unit that I am working on has invested a lot of time and energy into me but I just don't believe that it will be beneficial for either of us for me to stay on. How do I break this to my unit and department managers? Also, is it required for a nurse to give one month's notice? I thought that it was two weeks, but all of the places that I have interviewed at asked me if I needed to give my job one month's notice. Any and all advice appreciated.
