It is illegal to record someone without their permission, so allegations can be made against the employer in a legal court and if witnesses can stand forward then the judicial system will take it from there, but other than that nothing can be done against the employer. As for the claim, it is illegal for a claim to be used as a reason for firing a person, and legal action can be taken if the employer does.

In New York you can not collect both at the same time. If you can prove, which would be hard without physical evidence, that you were fired due to the injury you can sue the employer. But if you are collecting comp you can file a claim for unemployment but I would wait until the comp is up.
