Right now, I sub for 3 public school districts and 1 Catholic school. As a sub, I split my time between 10 schools total and operate on a first come, first serve basis. I've been thinking of adding a few m ore public districts and, quite possibly, a few more Catholic schools to my résumé of places to work. I seem to be able to handle everything I currently have and am working anywhere from 1 to 3 days a week. As much as the thought of taking on more excites me, I also wonder if I may be overdoing it just a bit if I went that route. What do the rest of you think? How many districts/schools is too many?
