Retroactive Promotions for Extended Detail to Higher Grade Position

An employee's entitlement to temporary retroactive promotions because of an improperly extended detail to a higher grade position was questioned. The GS-12 employee, who was detailed to a GS-14 position between July 17, 1972, and January 31, 1975, was entitled to a GS-13 promotion for 1 year, beginning on the 121st day of the detail, and to a GS-14 promotion for the remainder of the detail.
