First-Line Supervisors in the U.S. Postal Service

Due to the impact of first‑line supervisors on Postal Service operations, the OIG sought to gain an understanding of the structure, footprint within the organization, and investments made in first‑line supervisors. As such, key human capital and performance data related to first‑line supervisors was examined to assess patterns of historical performance, evaluate comparability across various categories, and identify relationships between first‑line supervisors and key performance metrics. This white paper provides the results of our assessment, including analyses of key operational, performance, and cost metrics that impact Postal Service operations.
