Retaliation and nepotism.

I have a question about the problem that I have experianced at the place of my employment. I have been employed by the local school district for the past three years. I am fully certified teacher who currently works on Ph.D. in education with excellent references and work history. I have been working as a substitute teacher, regular teacher (remember this position, I will get back to it later), and currently I work as a teacher assistant. I have graduated from the came school district and completed all of my student teaching seminars. All at the same place. However, I have experianced one problem recently that left me quiet shocked. This is what happened.
I am certified to teach social studies, grades 7-12. However, I have not been able to secure job position in my area. I am working as a teacher assistant. However, this last summer, a teaching position came up at the local school at the same district. According to the job posting, the candidates had to be NYS certified and the deadline to apply was 8/2/2010. I was really looking forward to it. However, I got interview on 7/20/2010. I met the Principal Mr. S.F. and the Department Head Mrs. G.L. They were the only people who conducted the interview which I found strange and uprofessional. Normally, interviews for teachers are conducted by at least 4-5 people. The interview did not last more than 7 minutes. I left the building and received a rejection letter dated 7/22/2010. My interview and rejection took place before the application deadline of 8/2/2010. However, I have found out that the person who got recommended and hired is Mr. J.Z. who never worked in our school district, however,he never workd in high school or middle school and was not even certified to teach. According to his resume that he posted online, he got hired right after the interview in July. Also before the application deadline of 8/2/2010. Mr. J.Z. is a son of a very respected businessman in our area and I was strongly convinced that his father "made a phone call" because he was the most unqualified for this job without any experiance and without certification. This is unusuall exception especially if we take in consideration that that particular shool has big problems and just recently had a state inspection. But, I have decided to complain to the school board and made a phone call to the Vice-president L.L. who came to my house to discuss the issue. It seems to me that the vice-president was familiar with the problem and that he has something to do with that. He took my resume and told me that he will call Principal S.F. and find out what happened. I received the phone call from the vice-president the following week and this is what he told me:
1. Mr. S.F., the principal, told him: "Do you know that this is the guy [me] who tried to run for the school board and to get some things done his way?" I never tried to run for the school board. I do not know what this man is talking about. To run for the school board you cannot be employed by the school district and you need at least 175 signatures from the people in our community. When I was student, I did question the board clerk how this process works but I never ran for the school board. Even if I did, can I be punished for running for the public office?
2. Mr. S.F., the principal, also stated the the ESL Coordinator for the district, B.L., (who used to be my boss when I had full time teaching job) did not give me a good reference. However, I have a reference letter with her original signature that she personally gave me. She said the niciest things about me. The vice-president L.L. also said that he spoke with her and she did not provide a good reference. I have a good letter of reference with her signature that she gave me and I used her for every job that I applied for. No wonder why I never received an interview. I am strongly convinced that she manipulated me and destroyed my professional growth.
But, I think that there is a bigger problem behind that.
On 12/12/2007, I was hired to be an ESL Teacher in Newcomers Class. The ESL Coordinator for our district, B.L., (the one I mentioned earlier) called me and explained what my job will be. I supposed to work with a group of ESL students (all Asians from Burma, one Vietnamese, and one Puertorican student)and teach them basic of English. I gladly accepted that position even though I am certifid to teach social studies. On the first day of my job I found something quiet shocking. The ESL class was located at the district administration building in the basement, not at the local high school whose principal is Mr. S.F., the above mentioned principal. Mrs. B.L. explained that that high school has the highest drop-out rate in the state and is afraid that these group of immigrants will decide to leave school at some point in the future and so they do not want them. This is open discrimination. Anyway, I was left to work alone with this group of wonderful students, ages 16-18. District did not give me a mentor since I was a new teacher and Mrs. B.L. never came to my classroom to do the evaluation on me. As the matter of fact, no one came to my classroom. I was not give the lesson plans or program to follow, students' names were not entered in the computer so I had to take attendance in the old fashioned way. Students did not receive report cards, did not have transportation to school even though they lived miles and miles away from school, and of course no lunches. No textbooks too. I was free to whatever I wanted. Also, these students were strictly ordered to use the back entrence to the building and not the front. Back entrence was much less visible. Also, we had visit from the local media and I was ordered not to give them any information. It seems to me that principal Mr. S.F. and the ESL Coordinator Mrs. B.L. purposly tried to discourage these students from going to regular school. Majorit of them were minors, less than 18.
However, one of my students, who was 16, could not stop asking me when he will go to the real school. I know that he is right. Minors should go to regular school and study regular courses such as math, science, art. The high school had excellent ESL programs. But they spoke enough English to survive. They should be given the opportunity. Anyway, I personally called the ESL Coordinator Mrs. B.L. and some officials from the high school and explained that I have a student who is eager to go to school and that he is only 16. I had to argue with the school officials and explained that this might be violations of their rights. They accepted this finally accepted this student. In my next meeting with Mrs. B.L. I explained that this may not be right because we have minors who are placed in some unknown class that has no value, grades, lesson plans, and that high school may be violating their rights. Again, she explained that the high school, whose principal is Mr. S.F. does not want them because they are students at-risk and may decide to drop out of school. I reminded this lady that I came to this country at the age of 16 and graduated in record time. Now, I am working on my Ph.D...She just smiled and said that I am "exception." Anyway, I managed to put at least one student in the regular school but at the end of the year they had no job for me. They explained that my position is on temporary bases and the person who came to replace me was Mr. M.B. who was not certified at all. I continued working as a teacher assistant at a different school and on my first day I have met a friend of mine, Mrs. H.G., who was 100% uncertified working in the ESL department whose coordinator Mrs. B.L. told me that they have no open positions for me. Once my employment as a regular teacher ended so did my union membership. The union representatives called me and explained that they found out that ESL Coordinator Mrs. B.L. supposed to do evaluation on my teaching performance but she never did and that they would take action but since I my union memebership ended, there is nothing they can do about it.
I am 100% convinced that ESL Coordinator B.L. and Principal S.F. are trying to remove me from their setting forever since I warrned them about that their practice may be illegal and may be violating civil rights.
I feel that I have been discriminated at that job interview, wrongfully accussed of running for the school board, and that false reference was provided. I was under impression that I am receiving good reference when in reality this lady was saying bad things about me and I have a good letter of reference with her signatur as well as many other documents that can prove that I am telling the truth. Do I have case to file a law s. ?
