D.C. Mun. Regs. tit. 8, r. 8-B1605
If a grievance is not resolved under §1604, it shall be presented by the employee to the employee's second level supervisor in the chain of command within five (5) days after receipt of the supervisor's decision or the expiration of the required period for a decision to be made in Step 1.
The Step 1 grievance appeal shall be in writing, shall contain the materials presented at Step 1 and enough details to clearly identify the basis for the appeal, and the relief sought by the employee. No new allegations may be added to the Step 2 grievance.
The second level supervisor shall review the grievance materials and advise the employee in writing of his or her decision within ten (10) days of receipt of the Step 1 grievance appeal or advise the employee of the need for additional information. The parties may agree to extend timeframes to permit the gathering of such additional information.
If the second level supervisor does not grant the relief sought by the employee, or lacks authority to grant the relief sought, the second level supervisor shall advise the employee in writing, stating the basis for the decision and inform the employee of his or her right to appeal the grievance to the Step 3 level within five (5) days from date of receipt of the Step 2 decision.
If the employee does not receive a written answer within ten (10) days following the second level supervisor's receipt of the Step 2 appeal (and the parties have not agreed upon an extension of time), or if the employee disagrees with the second level supervisor's decision, the employee shall have the right to appeal the grievance to Step 3.
