The distinction matters because the report includes some of the most consequential ideas postal employees could face: fewer career conversions, voluntary early retirement, reductions in force or layoffs where contracts permit, changes to collective bargaining, a cheaper pension model, different workers’ compensation rules, outsourced post offices and middle-mile transportation, and five-day delivery.
The OIG started from a stark financial picture. USPS recorded nearly $118 billion in cumulative losses after fiscal year 2006, lost almost $9 billion in FY2025 and warned that it could run out of cash in early 2027. The report concludes that no single option is likely to close the gap quickly, so it groups 15 options into four scenarios.
The 15 options, grouped by what they change
| Area | Options compiled by the OIG | Why employees should care |
|---|---|---|
| Revenue | Modify the Market Dominant price-cap system | Higher prices could help revenue but may accelerate mail-volume losses. |
| Government funding | Federal funding for the universal service obligation | Could preserve six-day delivery and the retail network without relying entirely on workforce cuts. |
| Workforce | Change workers’ compensation rules; restructure the workforce; modify collective-bargaining rules | These ideas directly affect FECA, career conversions, headcount, pay bargaining and layoff protections. |
| Benefits | Diversify CSRS/FERS and retiree-health investments; change CSRS cost allocation; adopt a new pension model; change retiree-health funding | Some options change USPS financing only; a new pension model could change benefits for current employees, new hires or both, depending on legislation. |
| Operations | Outsource middle mile; outsource retail; convert door delivery to curb or cluster boxes; reduce delivery days; stop selected USO services | These could reduce transportation, retail, clerk, carrier and management workhours or positions. |
The workforce numbers behind the report
The OIG says roughly 79,000 employees across the four major postal unions were retirement-eligible in FY2025, with another 89,000 expected to become eligible within five years. It identifies a hiring freeze, VERA, RIF or layoffs where contractually permitted as possible ways to reduce headcount.
For scale, the OIG estimates that a hypothetical 10% workforce reduction could save as much as $5.6 billion based on FY2025 compensation and benefits. It also warns that reducing headcount does not guarantee an equal reduction in workhours because the remaining employees may need to work more overtime.
The report separately estimates that if USPS had stopped automatic pre-career-to-career conversions after FY2024, FY2025 payroll costs could have been about $2.5 billion lower. The OIG calls this the high end of potential savings because the estimate does not subtract reduced productivity, recruitment costs or the effects of higher non-career turnover.
Collective bargaining and pay
One of the report’s most sensitive sections examines three possible bargaining changes: requiring interest arbitrators to consider USPS finances, changing cross-craft restrictions and ending collective bargaining over compensation. The paper models as much as $6.5 billion in annual base-wage savings if postal compensation were aligned with selected private-sector comparisons.
That $6.5 billion is a hypothetical upper-end model, not a scheduled wage cut. Ending bargaining over compensation would require Congress, and other changes would require legislation, arbitration rules or negotiations with the unions. The report itself acknowledges that reduced compensation could make recruiting and retention harder.
Could FERS be replaced?
The OIG lists several possible pension approaches: reducing USPS employer contributions, closing FERS to new postal employees, freezing future FERS accruals, or transitioning to a defined-contribution or hybrid model. It estimates USPS could avoid more than $5 billion in annual normal costs under the most extreme assumption that postal FERS benefits ended.
Congress would have to authorize a different pension model. The details would determine whether a change applied only to future hires or also affected current employees. Accrued benefits and transition rules would be central issues; the report does not erase anyone’s existing annuity.
Other retirement options in the paper are different: changing how CSRS costs are allocated or allowing retirement funds to use diversified investments could reduce USPS expenses without reducing the pension formula paid to employees.
Five-day delivery, post offices and door delivery
The OIG uses a PRC estimate that reducing residential mail and package delivery from six days to five could have saved approximately $3.4 billion in FY2024, before accounting for revenue losses. Congress mandated six-day delivery in the Postal Service Reform Act, so USPS cannot simply eliminate a delivery day on its own.
Outsourcing post offices without co-located delivery units is estimated to save $1.0–$1.6 billion annually. The report notes that the overall retail network still generates more revenue than it costs, even though many individual offices operate at a loss. It also acknowledges statutory and contractual barriers to widespread outsourcing.
Converting door delivery to curbside or cluster boxes could save at least $0.8 billion in the scenario model, partly by reducing carrier workhours. That would require major implementation, equipment and public-policy decisions rather than a quick management instruction.
The four scenarios and their tradeoffs
| Scenario | Estimated annual financial impact | Employee and service direction |
|---|---|---|
| 1. Maintain service with substantial government support | Up to $11.9 billion | Keeps six-day delivery, door delivery, current workforce composition and more than 30,000 postal facilities. Includes up to $6.6 billion in direct USO funding plus retirement-financing changes. |
| 2. Reduce controllable costs with government action | Up to $17.7 billion | Preserves current USO services but freezes career conversions, outsources middle mile and some retail, changes FECA rules and receives government support. |
| 3. Reduce service with minimal public funding | $21.8 billion | Models a 10% headcount reduction, five-day delivery, curb/cluster conversion, selected USO cuts and broader pricing authority. |
| 4. Financial self-sustainability with substantial service cuts | $31.4 billion | No operating subsidy; five-day delivery, an end to remaining USO services, bargaining rollbacks, a less expensive pension model, FECA changes and uncapped Market Dominant prices. |
What could happen first?
The paper is most useful as a map of the coming political argument. Options requiring Congress—five-day delivery, a new pension model, major bargaining changes or a FECA exemption—cannot be implemented through a local management directive. PRC approval, advisory proceedings or union negotiations apply to several others.
The ideas closest to existing USPS authority are operational changes such as transportation contracting and parts of retail strategy, but even those can trigger contractual, regulatory and practical limits. Attrition, hiring restraint and targeted early-outs are also more plausible near-term workforce tools than an immediate nationwide RIF.
The bottom line for postal employees
This report does not announce what USPS will do. It shows the scale of changes that policymakers may debate because ordinary cost cutting has not closed the financial gap. The two endpoints are clear: preserve service through federal support and retirement-financing reforms, or pursue self-sufficiency through significantly fewer employee protections, benefits and services.
Postal employees should watch for actual legislation, PRC filings, national-union notices, VERA authorizations and bargaining proposals. Those documents—not the existence of this white paper—will determine whether any option moves from a model to policy.
