I want to tell you that what really matters is how the parents felt about you. The people at your job only think about themselves. It's amazing how the idea of "what have you done for me lately" (like the past 5 minutes) pervades poor management. Try not to let it get you down.
If you can contact these parents whose kids have graduated from your center, tell them that you are looking for a job. Also try to get on in the public school system. If you could work school hours, it would help.
Good luck,
Dawn
