Your chances of winning a grievance depend on your evidence and preparation.
Grievances with strong documentation and clear contract violations have good success rates. Grievances based on emotions, assumptions, or weak evidence typically fail.
What helps you win:
- Clear evidence the employer violated your collective agreement or workplace policy
- Written documentation (emails, texts, witnesses)
- Consistent story that doesn’t change
- Following proper procedures and timelines
What hurts your chances:
- No evidence—just your word against theirs
- Missing deadlines to file
- Weak or vague complaints
- Exaggerating or lying about what happened
Who Attends a Grievance Meeting?
Typically present:
- You (the employee filing the grievance)
- Your union representative (if unionized) or your lawyer
- Management representative (often HR or your supervisor)
- Witnesses (if either side calls them)
- Note-taker (to record what’s discussed)
For arbitration hearings (if it goes that far):
- Arbitrator or mediator (neutral third party)
- Union lawyer or grievance officer
- Employer’s lawyer
- Expert witnesses (if applicable)
You typically won’t face your manager alone—you’ll have representation.
What Should You Say at a Grievance Meeting?
Be Clear and Factual
Stick to what happened, when it happened, and who was involved. Use specific dates, times, and examples.
Good: “On October 15, my manager told me I was being moved to the night shift without the 7-day notice required under Article 12 of our collective agreement.”
Bad: “My manager is always unfair to me.”
Focus on Contract Violations
Explain how the employer broke the rules. Reference your collective agreement, workplace policy, or employment standards.
Example: “Article 15.2 states employees must receive overtime pay for hours over 40 per week. I worked 48 hours the week of November 3 and was not paid overtime.”
Stay Calm and Professional
Even if you’re angry or upset, keep your emotions in check. Stick to facts, not feelings.
Answer Questions Honestly
If you don’t know something, say “I don’t know.” Don’t guess or make things up.
Bring Your Evidence
Reference your documentation—don’t rely on memory alone. Say things like: “According to this email dated…”
What NOT to Say in a Grievance Meeting
Don’t exaggerate or lie If you get caught stretching the truth, you lose credibility and likely lose your case.
Don’t make it personal Avoid attacking your manager’s character or making accusations you can’t prove. Focus on what they did, not who they are.
Don’t ramble or go off-topic Answer the question asked. Don’t bring up unrelated complaints or past issues unless they’re directly relevant.
Don’t admit fault unnecessarily If asked leading questions, be careful. For example, “You were late that day, weren’t you?” Answer truthfully but don’t volunteer extra information that hurts your case.
Don’t threaten or make demands Let the process work. Don’t say things like “If I don’t get what I want, I’m going to the media.”
Don’t use emotional language Phrases like “They hate me” or “This is so unfair” don’t help. Stick to facts and contract language.
Questions to Ask in a Grievance Meeting
To clarify the employer’s position:
- “Can you explain why this action was taken?”
- “Which policy or contract provision are you relying on?”
- “Do you have documentation supporting your decision?”
To establish facts:
- “Was this decision documented in writing?”
- “Who was involved in making this decision?”
- “When was I notified of this?”
To test their reasoning:
- “Has this policy been applied consistently to other employees?”
- “Why wasn’t I given the opportunity to respond before this action was taken?”
Don’t be aggressive—ask genuinely to understand their position and expose weaknesses in their case.
Examples of Grievance Outcomes

Example 2: Denied Overtime Pay

Example 3: Unfair Termination

Example 4: Harassment Complaint Ignored
