D.C. Mun. Regs. tit. 6, r. 6-B236
A demotion occurs when an employee is permanently reappointed from his or her current position to a new position at a lower equivalent grade or to a position with lesser promotional potential.
Demotions may be made within an agency or to another agency under the same personnel authority. Demotions are also authorized between personnel authorities provided both authorities agree to the position change.
A personnel authority may demote a Career Service employee for cause pursuant to the procedures established in Chapter 16, provided the employee qualifies for the new position.
An employee may voluntarily accept a demotion to a new position, provided the employee is qualified for and accepts the new position with the lesser rights or benefits in writing.
