My experience with workplace discrimination is that it is death by a thousand blows and it is very hard to pick a list of a few things that they did that were clearly discriminatory and violated the law. I am pretty pessimistic by and large of getting lawyers involved. It's frustrating to look for work when you need a job and one doesn't come a long right away. I recently went through 4 months of job hunting with my son and have a lot of sympathy for your situation but am not at all optimistic that you will get any satisfaction through the legal route. I hope I am wrong.
