Effects of Vacancies at the Merit Systems Protection Board, Statement of Valerie C. Brannon, Legislative Attorney, Before Committee on Oversight and Reform Subcommittee on Government Operations U.S. House of Representatives [February 28, 2019] [open pdf - 977KB]
"The MSPB [Merit Systems Protection Board] is principally tasked with 'review[ing] certain serious personnel actions against federal employees.' The President appoints Board members with the advice and consent of the Senate. The term for a Board member seat is seven years, but because terms are tied to the calendar year, running from the date of the expiration of the prior term rather than the date of the new member's appointment, the actual duration of a member's service may be slightly shorter. However, sitting members may potentially remain on the Board for up to a year beyond the seven-year term while awaiting the appointment of a successor."
