In addition to the pay bands in the career groups, the DoD proposal includes authority for a pay differential for those with supervisory duties of at least 10 percent. There also would be discretion to give higher pay to a supervisor who has a subordinate earning more than the supervisor. The differential would count toward retirement benefits but it would not continue if an employee receiving it left to take a position without such duties. In addition, pay for managers would be tied at least in part to organizational performance.
