After more than a year of bargaining, NPMHU and USPS moved beyond the June impasse. In Contract Update #16 on August 12, 2026, the union said it had initiated interest arbitration and that the parties were discussing selection of a neutral chair.
Here’s what happened, what the dispute resolution process looks like for mail handlers specifically, and what to watch over the coming months.
How the Talks Broke Down
NPMHU’s 2022–2025 National Agreement expired without a deal last year. Rather than immediately invoking dispute resolution, both sides agreed to extend negotiations, hoping to find a path forward. That extension bought nearly a year of additional bargaining — but it wasn’t enough.
NPMHU National President Paul Hogrogian sent a formal letter to USPS on June 5 confirming the impasse. The union’s stated sticking point was wages. In its Contract Update #15, NPMHU said the parties “remain divided on significant issues” and that “the terms offered by the Postal Service have fallen short” of achieving a wage package that fairly compensates mail handlers for the work they do.
That’s the cleaner version. The underlying reality is that USPS is bargaining three union contracts simultaneously during the worst financial crisis in its history — a $2 billion net loss in Q2 FY2026 alone — and management’s ability-to-pay argument at the table has never been stronger. NPMHU’s decision to invoke the PRA rather than accept those terms says the union believes it can do better through a neutral arbitrator than through continued direct bargaining.
August 12 Update: Arbitration Formally Initiated
Ten weeks after declaring impasse, the NPMHU has taken the next formal step. In Contract Update #16, issued August 12, 2026, the union announced it has initiated the process for starting interest arbitration under Section 1207(c) of the Postal Reorganization Act, as amended in 2006. In the union’s words, it is through that arbitration that the terms of the 2025 agreement will be set — the door on a negotiated deal is effectively closed.
The union was direct about why. The arbitration step follows more than a year of bargaining, including additional rounds of discussions that took place after the impasse declaration in June. Those extra sessions didn’t move the needle: the parties remain far apart on key economic issues, and the NPMHU says it is unlikely further discussions would produce an agreement.
How the panel gets picked
The arbitration will be run by a three-member panel chaired by a neutral arbitrator. The parties are currently discussing who that neutral will be. If they can’t agree, they’ll ask the Federal Mediation and Conciliation Service to produce a list of candidates, and each side will strike names from that list until one remains. It’s a slow process by design, and the NPMHU has said plainly that — with history as a guide — it will likely take several months to schedule, implement, and conduct the arbitration.
Why the other unions complicate this
One point from Update #16 deserves attention, because it explains why mail handler bargaining has been so difficult. The NPMHU noted that its dispute is complicated by what USPS has already settled elsewhere: the agreement reached with the APWU in 2024, the NALC’s arbitrated agreement decided in 2025, and the fact that the NALC is currently negotiating a successor to that arbitrated award. Arbitration panels lean heavily on comparability — what the other crafts got, and on what terms — so those three agreements will shape the frame the panel works within, for better or worse.
The NPMHU Dispute Resolution Process
The Postal Reorganization Act gives postal unions and USPS a specific framework for resolving bargaining impasses. It’s different in some details from private-sector labor law, but the general path looks like this:
The process has moved to arbitration. Update #16 says additional discussions after the impasse did not close the major economic gaps. The union initiated the interest-arbitration process under the Postal Reorganization Act.
Arbitration if mediation fails. If mediation doesn’t produce a tentative agreement, the dispute goes to binding interest arbitration. An arbitration panel — typically a neutral arbitrator plus one person from each side — reviews both parties’ final positions and issues a binding decision on every unresolved issue. Whatever the panel decides becomes the new contract.
Current contract stays in force. Throughout this entire process, the existing National Agreement remains in effect. Mail handlers’ current pay rates, shift differentials, overtime rules, and other working conditions don’t change until a new contract is either negotiated or arbitrated into existence.
Two Unions, One Crisis
The dispute is unfolding alongside other postal bargaining rounds and against the backdrop of USPS financial pressure. Comparability across crafts can become part of the record in interest arbitration.
This matters because arbitration panels do not operate in a vacuum. Prior postal agreements and awards can be cited as comparability evidence, while each union still presents its own bargaining record and proposals.
It also puts real pressure on Congress. All four union presidents sent a joint letter to Congress on May 1 calling for USPS’s $15 billion borrowing cap to be raised and pension accounting to be restructured. With three unions now in dispute resolution, that letter carries more urgency. An arbitrator who sees a financially stabilized USPS — due to Congressional action — will weigh the financial picture differently than one who sees a cash-strapped agency heading toward insolvency.
What’s at Stake for Mail Handlers
The core issue is wages, but several other contract items matter for mail handlers specifically.
General wage increases and COLA. NPMHU’s existing contract included cost-of-living adjustments tied to CPI. Maintaining full COLA protection and securing meaningful general wage increases is the union’s primary objective. The gap between what USPS offered and what NPMHU demanded is, at its core, a dollars-per-hour argument.
Mail handler assistant (MHA) conversions. MHAs are the pre-career tier in the mail handler craft — the equivalent of CCAs for carriers. NPMHU has consistently pushed for faster conversion timelines and stricter caps on the share of work performed by MHAs versus career employees. Management has an incentive to keep that ratio flexible, especially if workload drops.
Automation and job security. USPS has been deploying more automation in processing facilities for years. The contracts govern how those changes are implemented, how work is reassigned, and what protections career mail handlers have when machines take on tasks that were previously manual. These Article 12 (Principles of Seniority, Posting, and Reassignment) issues are a perennial sticking point.
Staffing levels and workload. Mail volume continues falling — down roughly 6% year-over-year in Q2. As less mail moves through processing facilities, management has an interest in reducing headcount. Article 6 protections against layoffs apply to career mail handlers with six or more years of service, but the contract language around excessing and reassignment is where the real battles happen.

NPMHU Contract Update #16. Issued August 12, it says the parties were discussing selection of the neutral arbitrator and that the process would likely take several months. Read later numbered updates directly on npmhu.org before relying on any timeline.
Other postal agreements. Update #16 says APWU and NALC agreements affect the frame for this dispute. Any later NALC outcome may also be relevant to the arbitration record.
Congressional action on USPS finances. A borrowing cap increase or pension accounting fix changes the arbitration calculus for every union simultaneously. Watch for movement in the House Oversight and Senate Homeland Security committees.
Alvarez & Marsal recommendations. The restructuring consultants USPS hired are expected to deliver their recommendations by September 30, 2026. If those recommendations target processing facility operations or workforce structure — where mail handlers work — they feed directly into what management argues it needs at the table.
