My Spouse Got Fired For Something He Didn’t Do. Where Do I Turn Him In?

My husband worked 3 years for this jerk and he gets a call 3 days after the new year from his boss telling him he’s fired because he’s supposed to do all the employees jobs there except drive they’re trucks (He was a truck driver). This guy was shady to begin with. He never paid for holidays. never gave vacations or personal days. He didn’t give health insurance. He illegally took money out of his paycheck too. He won’t pay for anything extra except for his 200,000 home and his brand new cars. Which is recent by the way. I want to know where I can turn this bastard in so he does’nt get away with this.
