Only system administrators can change an employee's cost center. Go to the left sidebar > Click on ''Administration'' > Click on ''Organization'' > click on ''Departments'' > Select the department > Click on the pencil button next to the field ''Cost Center''. The cost center is linked to a department. If a department's cost center is changed in the administration section of PeopleWeek, the cost center of all employees in that department will be automatically updated to the new cost center.
