After 20 years as a letter carrier — and several years serving as a union steward — I've learned that understanding the USPS grievance process is one of the most valuable skills you can develop to protect your rights and those of your coworkers. Whether you're facing an unfair disciplinary action, a contract violation, or a working condition dispute, knowing how to properly file and navigate a grievance can mean the difference between losing your case and winning the relief you deserve.

Article 15 of the National Agreement defines a grievance as "a dispute, difference, disagreement or complaint between the parties related to wages, hours, and conditions of employment." That's a broad definition, and it's intentionally broad — if management is violating the contract, you have the right to grieve it. Here's how the process works, step by step.

Step 1: Identify the Contract Violation and Apply the Just Cause Standard

Before you file anything, you need to understand exactly what contract violation has occurred. Your grievance must be rooted in a specific contractual provision, not just general dissatisfaction.

The National Agreement between NALC and USPS is your foundation. Most grievances fall into these categories:

• Disciplinary actions — suspensions, terminations, or adverse actions that violate the just cause standard under Article 16
• Overtime and scheduling violations — improper overtime assignments, OTDL bypasses, or violations of Article 8
• Working condition violations — inadequate breaks, denied leave, unsafe conditions under Article 14
• Pay and seniority violations — incorrect payment, improper route assignments, or seniority rights being ignored

For discipline cases, the JCAM lays out six just cause sub-questions that management must satisfy — and that stewards should check against. The August 2023 Contract Talk column summarized them clearly:

1. Is there a rule? Was the employee aware of the rule?
2. Is the rule reasonable?
3. Is the rule consistently and equitably enforced?
4. Was a thorough investigation completed?
5. Was the severity of discipline reasonably related to the infraction?
6. Was the disciplinary action taken in a timely manner?

If you can show that management failed on even one of these six questions, you have strong grounds to grieve. These aren't optional guidelines — they're the framework arbitrators use to evaluate every discipline case.

Before filing, document everything. Write down the date, time, what happened, what management said, and who witnessed it. Get copies of any written communications, timeclock records, or relevant documents. As the Summer 2013 NALC Activist put it: "It's not what you say happened that counts, but what you can prove happened."

Step 2: File at Informal Step A

The grievance procedure under Article 15 has distinct steps, and most grievances are resolved at Step A. But Step A itself has two parts — Informal and Formal — and understanding the difference matters.

Informal Step A

This is where it starts. The steward discusses the grievance with the carrier's immediate supervisor.

Here's the timeline:

• You have 14 days from when the union first became aware of the issue to initiate the grievance at Informal Step A
• The steward and supervisor discuss the facts and try to resolve it
• If it's not resolved, you have 7 days to appeal to Formal Step A

When filing, use PS Form 8190 — the Joint Step A Grievance Form. As the May 2024 Contract Talk column explained, your issue statement should always be framed as a question with two parts: the merits and the remedy. For example:

"Did management violate Article 16 and Section 115 of the M-39 Handbook via Article 19 of the National Agreement and lack just cause when a letter of warning was issued to the grievant dated [date] for unsatisfactory work performance, and if so, what is the appropriate remedy?"

That format — question on the merits plus question on the remedy — is what the national parties expect. If you have multiple violations in the same incident, each one gets its own issue statement on the PS Form 8190.

Formal Step A

If Informal Step A doesn't resolve the issue, the grievance moves to Formal Step A. This is a more structured meeting between the branch president (or designee) and the postmaster (or designee). At Formal Step A:

• Both sides develop the facts of the case
• Documents are exchanged — Article 15.2(d) requires that the parties' representatives "cooperate fully in developing all necessary facts"
• Management issues a written decision
• If denied, you have 7 days to appeal to Step B

This is where having arbitration precedent gives you leverage. When I can tell management that National Arbitrator Richard Mittenthal ruled in C-06238 that the 12- and 60-hour overtime limits under Article 8.5.G are "absolutes" that cannot be waived or volunteered beyond, the conversation changes. That's not my opinion — that's a national-level arbitration decision that every arbitrator in the country will follow.

Step 3: Step B — The Dispute Resolution Team

If your grievance is denied at Formal Step A, don't panic. Many grievances are denied initially, but that doesn't mean you've lost.

At Step B, a Dispute Resolution Team (DRT) — consisting of an NALC representative and a USPS representative — reviews the case jointly:

• The DRT reviews all the facts and documents developed at Step A
• The DRT has 14 days to issue a decision
• They can resolve the grievance, or it can be "impassed" (no agreement)
• If impassed, the National Business Agent may appeal to arbitration within 14 days of the Step B decision

The NALC processes roughly 33,000 grievance decisions per year through 58 full-time Step B teams, according to the Summer 2013 NALC Activist. About 14.8% of those are impasse decisions forwarded to National Business Agents. Of those, pre-arbitration discussions (under Article 15.4.A.4) settle over 80% of appealed cases, leaving roughly 750 cases that actually go to hearing each year.

Those numbers matter because they tell you something important: the system works. Most grievances get resolved before arbitration. But the grievances that win at every level are the ones with strong documentation and clear precedent.

Step 4: Gather Your Evidence and Build Your Case

Strong grievance cases are built on solid evidence. The Winter 2014 NALC Activist published detailed evidence checklists for common grievance types. Here's the core of what you need:

• Witness statements — written statements from coworkers who saw what happened. Interview witnesses as soon as possible; memories fade.
• USPS documentation — clock rings, TACS Employee Everything Reports, PS Forms 3996, written notices, employee records
• Contract references — specific articles and sections that were violated
• MRS documents — Step 4 settlements and MOUs where the national parties have already addressed the issue. For overtime cases, M-00833 (Joint Statement on Overtime) and M-00859 (12/60-hour limits) are frequently decisive. For route issues, M-00242 (comfort stops not deducted from street time) and M-00304 (no set walking pace) are foundational.
• Arbitration precedent — cases where arbitrators ruled on similar situations
• Compliance with procedures — proof that management didn't follow proper procedures (especially important for Article 16 discipline cases)

The NALC Shop Steward's Guide frames this with five questions every steward must answer before the case is complete:

1. Is there a violation of the National Agreement?
2. Did we properly frame the issue?
3. Did we determine all facts and document each one?
4. Do our contentions clearly explain the documented facts and how the National Agreement was violated?
5. Did we request an appropriate remedy?

If you can answer "yes" to all five, you have a complete grievance file — one that can speak for itself at Step B or arbitration without you needing to be in the room to explain it.

Step 5: Know When to Push for Arbitration

Not every case should go to arbitration — it's time-consuming and requires careful preparation. But some cases demand it.

You should push for arbitration when:

• The contract violation is clear and well-documented
• You have strong precedent supporting your position — landmark decisions like National Arbitrator Benjamin Aaron's ruling in C-03207 that management cannot reduce office time below the average standard allowable time, or National Arbitrator Howard Gamser's equitability remedy formula in NC-S-5426
• The remedy you're seeking is significant (back pay, reinstatement, removal of discipline)
• Management is unlikely to reverse its decision at Step B

Making Your Case Stronger

The difference between a weak grievance and a strong one comes down to preparation and access to information. A grievance that cites specific arbitration decisions — with arbitrator names, case numbers, and reasoning — is infinitely more powerful than one that relies on contract language alone. When you can reference National Arbitrator Mittenthal's ruling that the 12/60-hour limits are absolutes (C-06238), or National Arbitrator Snow's decision that management cannot use an "as needed" approach for T-6 string vacancies of five or more days (C-10254), you're not arguing — you're presenting established precedent.

CREA analyzes your situation against thousands of arbitration cases spanning 1970-2025 — including NALC-designated key decisions — plus 1,700+ MRS documents and 73 USPS manuals, surfacing the contract provisions, precedent, and handbook sections that apply to your specific grievance. It gives stewards the same research capability that used to require years of accumulated institutional knowledge.

Stewards who know their precedent win cases. Stewards who rely only on contract language lose them.
