Lawyer forced me to drop my case.?

Okay an attorney who I was paying to represent me against my union and employer called me up on a Wednesday and told me that I had to give him $ 10,000 in two days or he will withdraw from my case and I will have to drop my case against the union and company. When my mother and I asked why the case would be dropped he said that cases like this take a long time and it’s the best thing to do and the case was dropped. I was pretty much forced to drop my case against the union and company where the union forged grievances with my name on it and a company who destroyed my file of how they wrongfully terminated me. Just so you know he was paid 15,000 already and I never seen a day in court before my case was dropped. When he dropped my case that I wanted to continue was there something I was supposed to sign before the case was dropped, I really want to take him to the disciplinary board for this.
