Ethics in Nursing

My question is this, and I am hoping to get a positive thoughtful answer. In 1995, I started working in a County run Nursing School in New York, through an agency. My salary was $7.50 per hour and I stayed with them for five months, at that salary because I really wanted to support the small school and what it stood for.

While there, I realized that they were unfamiliar with technology and I offered to teach them how to use computer software. They agreed and offered me a real position.

I unboxed and set up PC's in a lab, and set one up on my desk as well to continue typing tests and what not for the school. I taught all the staff how to use computer software etc. Then I mentioned that I had a Masters Degree in Nutrition.

My direct supervisor began discussing writing a textbook for her students. As I worked in the school she and her co-author, spent hours speaking with me about 'Nutrition in the Lifecycle' and other coursework that I had taken, including many hours of psychology - at the graduate level. I spent many hours assisting my supervisor with her computer work, discussions about the topics in the text; and then she asked me to read, review and edit her morificecript. Then she must have realized something, and after I had completed four chapters with her, she stopped requesting assistance.

As she wrapped up her first textbook - I was let go from the organization. I was devastated by this turn of events and the cost of living in the New York area was so steep, that without a job I had to completely relocate.

What should I do? I feel that they two authors should include me in their percentage of earnings from the books.
