In recent months, we have been spending a lot of time at farewell parties as a trickle of federal retirements builds into a stream.

This year, a slew of people have either retired or announced that they intend to soon. They include Dee Lee, the General Services Administration’s David Bibb, the Army’s Vern Bettencourt, Lt. Gen. Charles Croom of the Defense Information Systems Agency, Lisa Akers of GSA.

The coming presidential transition is one reason for the rising tide of departures. Transitions are difficult for career employees because they are asked to carry a heavier workload until new political appointees are named — at which time they have to justify what they did during the transition. For many feds who have been in government for decades and worked for many presidential administrations, the upcoming transition seems like one too many.

Last week, there were two swan-song gatherings: one for Ed Meagher, who served as deputy chief information officer at the Interior and Veterans Affairs departments, and the other for Robert Burton, who has served as deputy administrator of the Office of Federal Procurement Policy for more than seven years. Later this month, Bob Suda will finish his 32-year federal career.

Those gatherings end up being half appreciations of long, distinguished careers and half roasts. At Meagher’s retirement party, Dick Burk, former chief architect at the Office of Management and Budget and one of Meagher’s college fraternity brothers, roasted Meagher the way only a friend who knows somebody for 40-plus years can.

That fun aside, one of the most touching parts of these retirement parties is the comments by the retirees themselves. Those speeches are partly science — always remember to thank your loved ones and your bosses — but they are also an art. The remarkable thing is that most people have repeatedly — and we believe sincerely — said how much they have loved their work. Despite the complaints from government workers, they usually do their jobs out of passion for the mission and because they believe they can make a difference and help people.

The turnover can be an opportunity to explore new ways for agencies to conduct their business. Meagher noted that the young people coming up through the ranks are bright and passionate, and they will find ways to get the work done. Their approach might be different from their predecessors, and that isn’t necessarily bad.
