is it legal for my boss to withhold corporate office contact information so I cant file a complaint?

Well on 3 separate occasions now, my gm/district manager has not only caused a hostile work environment, hes bad mouthed and tore me down to the entire restaurant of employees. Slander as well as defamation of character due to assumptions and false accusations. The most recent incident was about one week ago when he told every employee in the company to watch me because I was stealing, (including new employees that hadnt even met me yet), and during that time another manager had stolen $1,700. The only reason the manager had gotten away with it for so long is due to him having everybody watch me for false accusations. Once the truth came out it was the manager, they were fired and my boss told me to move on and get over it.
