5 CFR § 351.505 - Records.
(b) The agency must allow its retention registers and related records to be inspected by:
(2) An authorized representative of OPM.
(c) An employee who has received a specific notice of reduction in force under authority of subpart H of this part has the right to review any completed records used by the agency in a reduction in force action that was taken, or will be taken, against the employee, including:
(1) The complete retention register with the released employee's name and other relevant retention information (including the names of all other employees listed on that register, their individual service computation dates calculated under § 351.503(d), and their adjusted service computation dates calculated under § 351.503(e)) so that the employee may consider how the agency constructed the competitive level, and how the agency determined the relative retention standing of the competing employees; and
(2) The complete retention registers for other positions that could affect the composition of the employee's competitive level, and/or the determination of the employee's assignment rights (e.g., registers to which the released employee may have potential assignment rights under § 351.701(b) and (c)).
(f) The agency must preserve all registers and records relating to a reduction in force for at least 1 year after the date it issues a specific reduction in force notice.
