I am a substitute teacher so it is easy for my to pick and choose when I work. But recently I find myself not being ae to go to work. Ill sign up for a job with the intention of going but end up canceling the night before or morning off. I need to work, I need the money. I feel very vulnerable going into a school I have never been before. I feel judged. U am going to school to be a teacher so this is a perfect networking opportunity to show the principals my skills. Instead I am afraid I will make a mistake and they will always remember, next time I sub or if I were to apply for a job there. So I end up not going. Which is not helping me at all. Please any advise is greatly appreciated.
