So I just finished grad school and took a maternity leave position at a small private school. I've been there for about 2 weeks and I'm locked in for 4 more. On Saturday I got a call from a principal in a public school who told me that I came highly recommended by one of my supervisors who worked with me during my student teaching course. They are in immediate need of a teacher. What are my options here? I know deep down that it would be morally wrong to give up the sub position so quickly, but the logical part of me remembers filling out 255 job applications this summer. What should I do?!
