“One may authorize another to act on one’s behalf in transactions with third persons. This relationship is called “agency.” The person giving the authority is called the “principal”; the person to whom authority is given is called the “agent.” An employer/A principal is responsible for harm caused by the wrongful conduct of its employees/agents while acting within the scope of their employment/authority. An employee/agent is always responsible for harm caused by her own wrongful conduct, whether or not the employer/principal is also liable.”
