How to organize records for a union grievance

A union grievance is a formal claim that a workplace policy, practice, or action violated the collective bargaining agreement. Grievances succeed or fail based on documentation. The union representative needs specific facts - dates, communications, policy references - to build the case. The more organized your records are when you bring them to your representative, the stronger your position.

This article covers practical documentation approaches for grievance preparation. It is not legal advice and does not replace consultation with your union representative or a labor attorney.

What a grievance requires

Most grievance procedures follow a structured format. The grievance filing itself typically needs:

A description of the incident or practice being grieved
The date(s) of the incident
The specific contract provision(s) violated
The remedy you're seeking
Supporting documentation

The filing is your representative's job, with your input. Your job is to provide the raw material - the facts, the records, and the context - in a form they can work with.

Start with the facts

Before organizing anything, write a chronological account of what happened. Focus on facts rather than interpretations.

Useful: "On March 3, my supervisor informed me by email that my shift was being changed from days to nights starting March 10, with no explanation of the reason."

Less useful: "My supervisor changed my shift to punish me for filing a complaint."

The interpretation may be accurate, but it's the facts that build the case. Your representative will assess the pattern and draw conclusions based on the evidence. Give them the evidence first.

For each incident relevant to the grievance, note:

The date and time
What happened, in specific terms
Who was involved (names and roles)
Who witnessed it
How it was communicated (in person, email, text, posted notice)
Your response, if any
What happened next

Contemporaneous documentation

The most credible records are contemporaneous - created at or near the time of the incident, not reconstructed later. If you have messages, emails, or notes from the time of the incident, those carry more weight than a summary written weeks later.

If you don't have contemporaneous records, create them now while the details are still fresh. Write a dated account of what happened and when. Note explicitly that you're recording the events from memory and include as many verifiable details as possible - dates, people present, location, the channel of communication.

Going forward, if you anticipate that a situation may become a grievance, start documenting in real time. Send yourself a brief email after each relevant incident. Save text messages from supervisors. Keep copies of schedule postings, policy notices, and any written directives.

Organizing your records

Your union representative will need to review your records quickly and identify the strongest evidence. Organization matters.

Create a timeline. List every relevant incident in chronological order. For each entry, include the date, a brief description, and a reference to supporting documentation ("see email from J. Torres, March 3" or "see attached schedule posting").

Gather supporting documents. Collect everything that corroborates your timeline:

Emails and messages from management related to the issue
Schedule postings or changes
Written warnings, performance reviews, or disciplinary actions
Policy documents or handbook excerpts relevant to the grievance
Photos of posted notices or workplace conditions, if relevant

Organize by incident. If the grievance involves multiple incidents (for example, a pattern of schedule changes that violate seniority provisions), group your documentation by incident while maintaining the overall chronological order. Each incident should have its own supporting documents clearly labeled.

Include the contract language. Identify the specific contract provisions you believe were violated. Print or copy the relevant sections. Your representative knows the contract, but showing them exactly which provisions you're referencing demonstrates that you've done your homework and speeds up their review.

Communication records as evidence

Workplace communication records - emails, text messages, messages through workplace platforms - are often the strongest grievance evidence because they're timestamped and verbatim.

Save any messages from management that:

Communicate the decision or action you're grieving
Contradict earlier instructions or commitments
Show inconsistent application of policy (one standard for you, a different standard for a coworker in the same situation)
Acknowledge that the action was taken and provide a rationale
Respond to your questions or objections about the action

If relevant conversations happened verbally, send a follow-up in writing when possible: "Following up on our conversation today - you mentioned that the schedule change is being made because of operational needs. Can you provide more detail about what those needs are?" This creates a record of the rationale, which may become relevant if the reason given changes later.

Export or screenshot messages rather than relying on them staying in the original platform. Workplace communication systems are controlled by the employer. Messages can be deleted, accounts can be modified, and platform access can be revoked. Preserve your records independently.

What your representative needs from you

When you bring your records to your union representative, they need to quickly understand three things: what happened, what contract provision was violated, and what remedy you're seeking.

Present your timeline first. Let them read it and ask questions. Then walk through the supporting documentation, connecting each document to the relevant point on the timeline.

Be prepared to discuss:

Whether the same policy or practice has been applied differently to other workers
Whether you raised the issue informally before filing the grievance
What management's stated rationale is for the action
Whether similar grievances have been filed and what the outcomes were
What resolution you want

Timeliness

Grievance procedures have deadlines. Most contracts specify a window - often 10 to 30 days from the incident or from when you became aware of it - within which the grievance must be filed. Missing this window can forfeit your right to grieve the issue regardless of how strong the evidence is.

Check your contract for the filing deadline as soon as you identify a potential grievance. Note the date and work backward from it. Your documentation doesn't need to be perfect before filing - you can supplement the record after the grievance is filed. But the filing itself needs to happen within the contractual timeframe.

If you're unsure whether something is grievable, talk to your representative early. They can advise on whether the issue is covered by the contract and what the timeline is for filing.

Receipts helps organize communication records into structured chronological timelines - turning scattered emails, messages, and notes into clear documentation for workplace disputes.
