My sister is graduating this year with her bachelor's degree in teaching, she majored in early childhood development and is going to be an elementry school teacher. I know that with us, the degree does nto always mean a job, but it helps.
I live in Michigan, and Michigan is what is called an At Will employment state. this means that an employer can let you go for any reason they would like that is within the confines of the law. So consequently I have been fired for having my disability, but it was hidden behind other, perfectly legal explainations.
All we can do is go in and work hard and hope that some one will notice. Practice interviewing skills, amd practice talking about your disability in a way that sounds like you have made your disability a posative thing in your life. Employers often take that as a strength rather than a weakness.
Beauty Queen, aside from being as wrong as your boss was, I would want to find a different job after that, I would never want to work for some one that was looking for me to fail. try other schools in your area, they might be looking for someone to do the same job that you were doing before.
