Need help with forgery and fraud by my union?

Back early this year it came to my knowledge that the union I was a member of committed forgery by signing my name on a grievance and passing it off as my own because they did not do their job to represent me the right way so they threw out my real grievance and made up a forged one doing what ever they wanted with it to keep me from getting my job back while at the same time trying to hide fact that I was not represented fairly by my union. Local Lodge Shop Stewards forged my name, a Local Lodge Committee Official illegally signed off on it, even the Assistant General Chairman of the Local Lodge knew about the forgery but to protect the others who committed the crime and himself he told the Grand Lodge Representative that I didn’t want my job back and that the grievance the union forged was withdrawn at my request so that the people on the local level wouldn’t get in trouble along with himself knowing what they did was wrong but he went along with it anyway. I would like to know if there is way to get justice against my union for committing this crime of forgery and fraud against me, I have a lot of documents that can prove this forgery. I have been everywhere looking for help but its like most lawyers out here represent the criminals not the one who were done wrong most importantly do I have a case.
