Re: ethical or not?
I have moved around quite a bit during my nursing career. I always have another job lined up prior to giving notice to the current employer. I usually use one or more co-workers as references so my employer most of the time was not surprised when I turned in my notice. Two unit managers were notified a few months ahead as I was sure I would be leaving. Other jobs just got the standard 2 weeks notice. My one salary position got its 4 weeks notice and I also stayed on part time to finish orienting a new employee.
I also don't give negative feedback on my exit interviews. I have given positive encouragement on their attempts to correct the problems that bothered me at a few places though.
I have been rehired by two employers and am probably going back to a local agency in the next 6 months that I worked for about 7 years ago.
Most of my reasons for quitting are because I want to broaden my experience. In reality I am bored or don't feel like going to work at the current job anymore...typical burnout with the problems that are bothering me at the time have not been addressed or corrected etc. It is surprising how much you can overlook if you really enjoy the job you are in.
Good luck, search to your hearts content while having an income!!!
