A lead worker is an employee who has some oversight responsibilities for a group of employees working on a project or a specific assignment basis. The lead worker does not have full formal supervisory authority for staff assigned; however, in order to complete project assignments, the lead worker must be able to schedule and control the daily working arrangements for that group of employees. For a full definition, see the guideline for Lead Workers.
A supervisor is an employee who customarily and regularly directs the work of two or more permanent employees, and has the authority to make decisions or effective recommendations regarding hiring, evaluating, disciplining, or dismissing those employees. For a full definition, see the guideline for Supervisors.
