What Is a Grievance? A Simple Guide for Workers and Union Members
· 7 minute read · Aaron Beaudry

A grievance is a formal complaint that the employer has violated the collective agreement. Sometimes it also alleges a breach of law or a workplace policy the agreement incorporates. It is not a vent. It is not “I don’t like my supervisor.” It is a claim with a legal shape: what happened, which article was broken, and what it will take to put the member back in the position they would have been in if the employer had followed the contract.
That last part is the redress. Without redress, you have a story. Arbitrators do not award stories.
Three kinds, one idea
- Individual — one member, one set of facts. Discipline, a denied overtime, a missed posting.
- Group — the same breach hit more than one person in the same way.
- Policy — the rule itself is wrong, even before it lands on a named member. Drug-testing policies, attendance programs, a new “availability” rule.
The paperwork looks similar. The difference is the ask. An individual grievance usually wants a person made whole. A policy grievance wants the rule pulled or rewritten so it stops producing the same harm.
It is not the same as everything else
Talking to the boss is not a grievance. A human rights application is not a grievance. A WSIB form is not a grievance. A ministry complaint is not a grievance. Those paths exist, and sometimes they run beside the grievance procedure. They do not replace it, and they do not pause your time limits.
Who actually files
In a unionized workplace the union owns the grievance. The member brings the facts. The steward helps build the grievance. The union decides whether to file, how far to take it, and whether to settle. That is the duty of fair representation: the union has to consider the grievance honestly, not perfectly, and not for a bad-faith reason. “I want my day in court” is not a right the agreement gives the member. “I want my steward to look at this before the clock runs out” is.
What belongs in a grievance
- What happened, in order, with dates and times.
- Who was there and who said what — names, not “someone from HR.”
- The article or articles you say were broken. If you are not sure, name the ones that might apply and keep investigating.
- The redress: reverse the discipline, pay the overtime, post the job, cease applying the rule.
- Documents: the letter, the schedule, the email, the medical note, the seniority list.
What does not belong: adjectives. “Unfair,” “disrespectful,” and “harassment” are conclusions. Put the facts under them. If a supervisor raised their voice on the floor on Tuesday at 14:10 in front of three named co-workers, write that. The arbitrator will decide what to call it.
The path, in shop-floor English
Complaint to the steward. Filing. A meeting at step one, often with the front-line supervisor. A meeting at step two, often with labour relations. Then, if it is still alive, a referral to arbitration. Each step is a chance to settle. It is also a chance to learn what the employer’s real story is. Take notes. Do not rely on memory. Do not sign a settlement you have not read.
A grievance is won or lost in the first week, in the particulars, and in the paper. The hearing is where that work shows up — or doesn’t.
If you think something is grievable, talk to your steward now. Bring the letter. Bring the dates. Do not wait until you have “the whole story.” Time limits do not wait for the whole story.
