Negligence in employment encompasses several causes of action in tort law that arise where an employer is held liable for the tortious acts of an employee because that employer was negligent in providing the employee with the ability to engage in a particular act. Four basic causes of action may arise from such a scenario: negligent hiring, negligent retention, negligent supervision and negligent training. While negligence in employment may overlap with negligent entrustment and vicarious liability, the concepts are distinct grounds of liability. The doctrine that an employer is liable for torts committed by employees within the scope of their employment is called respondeat superior.
