A tort can be said to be a wrongful action which is injurious to another person or interferes with the property of another party (Luntz, Hambly et al. 2017). A tort case is purely a civil proceeding in court. On the other hand, a crime is an illegality or an action which has been identified by a government, either state of federal to be a wrongful action hence a crime. As such, a family can indeed sue a company for an assault at the workplace if a member of the family is assaulted. To prevent such a problem from occurring, the company can pass laws and code of conduct to make an individual personally liable for any action (assault) they take against a member. A person can only thus be answerable for a wrongful action committed to another employee such that the case can be a criminal case where the plaintiff is a witness of the state or company. Additionally, the company must invest in alternative dispute resolution mechanisms which are settled out of court.
