I am a RN and have worked 12 years in a hospital setting until I resigned from my job two weeks ago. I had been feeling real burn out and not want to return to work for a while but I was just recently offered a nurse substitute position at a local school district. My question is how often will I be working? I really don't want to work very much. The school district consists of 1 high school, 2 junior highs, and about 5 elementary schools. Also, do they call you the morning of or night before? Thanks for any info.
