These claims are based on the negligence of the employer, rather than on vicarious liability. Generally, an employer has an obligation to its customers to reasonably inquire into an employee’s past record and employment if, for example, an employee will have un-monitored access to customers’ homes in the course of the employment. An employer may also be liable for negligently entrusting an employee to use a vehicle or other property if the employer knew or should have known that the employee might use the property in a way that would involve an unreasonable risk of harm.
