District of Columbia Code Division I. Government of District. § 1-617.06. Employee rights.

(a) All employees shall have the right:

(b) Notwithstanding any other provision in this chapter, an individual employee may present a grievance at any time to his or her employer without the intervention of a labor organization: Provided, however, that the exclusive representative is afforded an effective opportunity to be present and to offer its view at any meetings held to adjust the complaint. Any employee or employees who utilize this avenue of presenting personal complaints to the employer may not do so under the name, or by representation, of a labor organization. Adjustments of grievances must be consistent with the terms of the applicable collective bargaining agreement. Where the employee is not represented by the union with exclusive recognition for the unit, no adjustment of a grievance shall be considered as a precedent or as relevant either to the interpretation of the collective bargaining agreement or to the adjustment of other grievances.
