I spent a year as a sub and it is a real job if you make it one. (I deal with a lot of people, not professionals, who come do it as babysitting and get paid to do nothing. I had several of them in my building today. UGH!!!) Anyway, it is a fantastic way for you to get back into teaching and get your feet wet. Yes, we have gotten subs for the sub. Always remember that your children come first.
