Matching workforce to workload has been a long-term struggle for the U.S. Postal Service. In its banner years, when volume was increasing, the Postal Service often found it difficult to quickly reduce workhours to offset seasonal dips in mail volume. Over the past 6 years, as volumes have steadily declined, the Postal Service has done a better job of matching its work hours to its workload. It has its lowest number of career employees in 25 years and productivity has seen steady cumulative improvement.
