In order to establish a cause of action based on negligent hiring, negligent retention, or negligent supervision, it must be shown that the employer knew or should have known of the employee's propensity for the conduct which caused the plaintiff's injury. Here, the amended complaint failed to state a cause of action to recover damages for negligent hiring and retention since it failed to allege that the defendant knew, or should have known, of a propensity on the part of any employee or employees to commit an alleged wrongful act.
