In general, a key holder has management duties and is responsible for the workplace when neither the manager nor assistant manager is available. The specific tasks depend upon the type of business or industry.
Someone hired for a position with key holder responsibilities receives the same training as the manager and assistant manager. These responsibilities include opening and closing the business, setting goals and delegating job responsibilities. In addition, the key holder is a liaison between the management and the employees. An individual in this position helps motivate employees, assists managers in their functions and facilitates communication between workers and administration.
