My wife and I work for an organization that provides housing for people with disabilities. The client after getting home from work was angry and started yelling at my wife in the dining room as I got up to see what was wrong he started yelling at myself and as I tried to calm him down he stepped forward and hit me with a closed fist, at that time he raised his fist again as to him me once more or my wife who was standing next to me, I in reaction hit him in an attempt to get him to stop. He was removed from our house and we (my wife and I) were terminated.
Are there laws that say I have the right to protect myself and or my wife?
Also why was my wife terminated if she was an innocent bystander?
