How to file a grievance, step by step

A grievance is the formal way you enforce your contract. If UPS violates the National Master Agreement, your supplement, or a past practice — a missed guarantee, a supervisor doing your work, unfair discipline, a skipped seniority right — the grievance procedure is how you get it fixed and made right.

You don't have to figure this out alone, and you don't have to be sure you're right before you act. Your steward is there to help you decide whether you have a grievance and to file it with you. This guide walks through the steps in order so you know what to expect. The one thing that matters most: act quickly, because filing windows are short and vary by local.

Steps to file a grievance

  1. Talk to your steward first

    Your shop steward is your first call. Stewards are trained to spot grievances, know your building's history, and file with you — that's their job, and talking to them costs you nothing. Bring them the basic facts and let them help you decide whether what happened is a contract violation.

    If you can't reach your steward, contact your local union hall. Don't let not knowing who to talk to stop you — the clock is usually running from the day the problem happened.

    Ask about stewards and where to start

  2. Know your filing window — and don't wait

    Grievances must be filed in writing within a set window after the incident (or the date you knew, or should have known, about it). That window is short — often just a handful of working days — and it's set in your supplement or rider, not the National Master, so it varies by local.

    Missing the deadline is the single most common reason a valid grievance gets denied. When in doubt, file. It's far better to file and be told there's no violation than to miss the window on a grievance you would have won.

  3. Write down what happened

    As soon as you can, write down the facts while they're fresh: the date, time, and place; who was involved; what was said and done; and which supervisor or manager was there. Specifics win grievances — 'on Tuesday the 14th at about 5:40 PM, my supervisor loaded three trucks' beats 'supervisors keep working.'

    Note anything that shows the violation: your start and end times, the guarantee you were owed, the seniority list, the discipline notice, photos, or the names of coworkers who saw it. Keep your own copy of everything.

  4. Gather what you'll need

    Pull together the documents that back up your grievance before you file. Depending on the issue, that can include your timecard or punch detail, your seniority date, the relevant contract article, a copy of any warning letter or discipline, and the names of witnesses who are willing to confirm what happened.

    You don't need a perfect case to file — your steward and the union will develop it — but the more you bring, the stronger the grievance starts out.

  5. File the grievance form

    With your steward, fill out your local's grievance form. State the facts plainly, cite the article(s) you believe were violated if you know them (your steward can help), and say what remedy you're asking for — for example, being made whole for lost hours, the discipline removed, or the seniority right restored.

    Sign and date it, submit it through your steward or local per your supplement's procedure, and keep a copy of the filed form for your records.

    Ask how to file and what to request

  6. Track the response and next steps

    Once filed, your grievance moves through the steps in your contract — typically a local-level hearing first, then higher panels if it isn't resolved. Each step has its own time limits, so stay in touch with your steward and respond quickly if the union needs more from you.

    Keep your copies, note every date, and follow up. If the company misses a deadline or the grievance is denied, the contract lays out how it advances. Your steward and business agent carry it forward — your job is to stay engaged and keep records.

Grievance FAQ

What exactly is a grievance?
A grievance is a formal complaint that UPS violated the contract — the National Master Agreement, your supplement or rider, or an established past practice. It's the enforcement tool that turns the words in your contract into action, covering things like missed guarantees, supervisors doing bargaining-unit work, unfair or excessive discipline, skipped seniority rights, and pay shortages.
How long do I have to file a grievance?
The filing window is set in your supplement or rider, not the National Master, so it varies by local — but it's always short, commonly just a handful of working days from the incident or the date you knew about it. Because a missed deadline can sink an otherwise winning grievance, the safest move is to tell your steward right away and file promptly. Ask TeamstersGPT with your supplement selected for the exact window.
Will I get in trouble for filing a grievance?
No. Filing a grievance is a protected right under your contract and federal labor law, and the company cannot lawfully retaliate against you for using the procedure. If you ever feel you're being retaliated against for filing, tell your steward immediately — that's a separate violation you can grieve.
What if I'm not sure I even have a grievance?
That's exactly what your steward is for. You don't need to be certain before you speak up — describe what happened and let your steward help you decide. Because filing windows are short, it's better to raise it early and learn there's no violation than to sit on a real grievance until the deadline passes.
