This report presents the results of our audit of Postal Service Management of Overtime Hours.

Background

The Postal Service designates overtime hours as any workhours an employee has worked in excess of a standard workday and/or workweek. The Postal Service generally categorizes overtime hours as either regular overtime or penalty overtime. Regular overtime is paid at time and a half to eligible employees, while penalty-overtime is paid to eligible employees at double the employee’s hourly rate under specific conditions spelled out in collective bargaining agreements. Facility management is required to manage overtime hours efficiently, as overtime hours represent a significant cost for the organization. During fiscal years (FY) 2021 through 2024, the Postal Service paid $24.3 billion in total overtime costs.

What We Did

Our objective was to evaluate the Postal Service’s management of overtime hours and assess whether the corrective actions taken in response to prior overtime audits sufficiently addressed the issues identified. For this audit, we analyzed nationwide overtime data and compared actual overtime to planned overtime hours during FY 2021 through FY 2024. We reviewed overtime hours of 20 judgmentally selected facilities and held interviews with headquarters, district/division, and local officials to gain an understanding of the overtime documentation process including unauthorized overtime.

What We Found

Overtime hours have declined from 172.9 million in 2021 to 117.8 million in 2024. Even with this decline, opportunities continue to exist to improve the management of unauthorized overtime in the Time and Attendance Collection System (TACS) and further reduce overtime hours. Specifically, facility management did not always properly identify, categorize, and document regular and penalty overtime transactions in TACS by the end of the pay week, as required. Additionally, although total overtime hours declined by more than 30 percent from 2021 to 2024, the Postal Service used 5.7 million overtime hours, or 5 percent more than originally planned, in FY 2024.

OIG conducted an evaluation of the Volunteer Delivery System to assess the challenges Peace Corps has recently faced in recruiting, selecting, and placing Volunteers. To perform this evaluation, OIG reviewed the agency’s strategic planning and performance documents, recruiting and hiring data, and documentation related to various recruiting strategies. OIG also conducted in-person and virtual interviews with headquarters-based and regional recruitment staff. The evaluation also included an overseas staff survey and a review of relevant documentation. The report contains seven recommendations along with a summary of the effectiveness of Peace Corps’ recruitment strategies and approaches.

The U.S. AbilityOne Commission Office of Inspector General (OIG) conducted an investigation in response to an anonymous complaint alleging that a sole source contract was improperly awarded.

The objective of our review was to determine whether the U.S. Department of Education (Department) complied with transfer of funds and reprogramming requirements under appropriations laws. To achieve our objective, we identified the Department’s transfer and reprogramming activities from November 5, 2024, through January 20, 2025, and the extent to which these activities complied with applicable appropriations laws.  We found that the Department did not fully comply with transfer of funds and reprogramming requirements under applicable appropriations laws. We identified a total of six transactions, consisting of five transfers and one reprogramming, that occurred from November 5, 2024, through January 20, 2025. We determined that two of these transactions—one of the transfers and the one reprogramming—were made using authorities granted under applicable appropriations laws. For these two transactions, we found that the transfer was compliant with applicable requirements; the reprogramming was not. Specifically, we found that the Department did not consult or notify Congress of the reprogramming as required by the appropriations laws. The remaining four transfers were appropriately made under other statutory authorities. The Department’s failure to comply with applicable statutory transfer authorities and reprogramming requirements may result in Federal funds not being used as originally intended by Congress, funds being deemed unavailable for obligation, and potential violations of the Antideficiency Act. Additionally, failure to notify Congress of transfers of funds and reprogrammings hinders congressional oversight of how agencies execute their budgets and fulfill their missions. We recommended that the Department establish appropriate controls to ensure that transfers of funds and reprogrammings comply with all applicable statutory authority requirements, including notifications to the House and Senate Appropriations Committees. 

To ensure the continued operations of the International Space Station and the safety of the crew, NASA and its spacesuit support contractor must ensure the suits used for spacewalks, designed more than 50 years ago, are well-maintained and reliable. The contractor, Collins Aerospace, has struggled to ensure sufficient life support components for the suits are delivered when needed and within budget and that meet quality expectations. While Collins’ performance over the last several years has declined, NASA has limited leverage to incentivize improved performance.

OIG contracted an Independent Public Accounting firm to review the Rural Utilities Service’s process for evaluating and prioritizing the level of service provided for its broadband program, as well as how the current mapping software addresses previously identified programming errors.

In August 2022, the PACT Act significantly expanded veterans’ eligibility for benefits and services for conditions related to toxic exposure. The expansion added further complexity to VBA’s claims determination process, particularly given the voluminous guidance issued for nonpresumptive conditions—those conditions for which service connection cannot be granted on a presumptive basis. Notably, the law opened a new path for service connection for veterans with nonpresumptive conditions related to toxic exposure risk activity (TERA). The VA OIG conducted this review from October 2023 through May 2025 to determine whether VBA staff processed decisions in compliance with TERA procedures under the PACT Act that denied nonpresumptive conditions. The OIG focused on denials because of the potential impact of incorrect decisions on benefits received by veterans.

The review found VBA’s oversight lagged in ensuring accurate processing of nonpresumptive conditions under the PACT Act. While VBA took steps to improve PACT Act claims processing, these efforts have not remedied the problem of various inaccuracies related to nonpresumptive conditions. An OIG statistical analysis estimated 61 percent of all nonpresumptive, TERA-related decisions under the PACT Act that VBA denied from May 1 through August 31, 2023, had processing errors—some of which could have affected veterans’ benefits. For example, some errors showed that claims processors did not accurately identify toxic exposure claims, research and verify veterans’ participation in a TERA, request a medical exam and opinion regarding toxic exposure, or appropriately include key information in decisions for nonpresumptive conditions. Furthermore, PACT Act guidance is difficult for staff to navigate because it is frequently updated and spread among several different sources. VBA needs to improve its oversight to mitigate and prevent inconsistencies and errors. VBA concurred with the OIG’s three recommendations to correct processing errors, consolidate guidance, and evaluate controls.
