I had to sub for two long years before class size reduction in the late 90s provided the first new teacher openings in over 5 years. Long term sub jobs were what kept me sane and fed. I knew the class, could actually teach and not just mange the classroom for a day at a time, and it paid $10 more a day. I knew the other teachers, students were comfortable with me and it actually helped me get a permanent position when they finally were available. There had been a strike and I didn't cross the picket line like some other subs did. The teachers remembered that I actually marched with them, in the rain. They recommended me for the first new opening and I got two offers due to not crossing the picket line.
Once I was teaching I was sick constantly (even more than when I was working at various dept stores selling products). The K-3 germs are year round and the school was too cheap to get subs. I almost died once. The schools have no windows and the air systems never got cleaned or filters replaced. Mold was everywhere and my bldg had to be torn down due to it. I have permanent health damage as a result. You are smart...your health is more important than anything.
