I agree with the posters who said the transfer or "demotion" as OP called it, happened for a reason. Who knows OP, maybe you may like the new unit better whether it's the work load, supportive staff, or a better group of nurses on the shift. Some nurses still succumb to mob mentality or may have not liked you for whatever reason (that's life). I remember when I was a new nurse of 6 months, a newer nurse started. One group of nurses didn't like her; one evening they were talking bad about her. I interjected and said what they were stating wasn't true and I gave examples. They told me to mind my business. A month later the young lady turned in her letter of resignation. I believe everything happens for a reason. We may not know why at the moment, but somewhere along the way the reason is revealed. Good luck OP!
