Discipline Grievances
From verbal warnings to suspensions, Sertus tracks discipline patterns across the bargaining unit and prepares step responses grounded in the collective agreement.
The shape of a discipline grievance
Discipline is the everyday currency of labour relations. A single suspension rarely looks dramatic in isolation, but the pattern across the bargaining unit matters, and so does the rigour of the investigation that produced it. Canadian arbitrators consistently ask the same questions before upholding or overturning a disciplinary penalty.
Progressive discipline is the organising principle. Canadian arbitrators expect the penalty to reflect a considered progression rather than a single leap — a verbal warning, a written warning, a short suspension, a longer suspension, and only then discharge, with room for the employer to skip steps in cases of serious misconduct. The point of the progression is not ritual but notice: the grievor must have a meaningful opportunity to correct the conduct before facing a penalty that threatens the employment relationship. Where the employer has skipped steps, applied the standard inconsistently across the bargaining unit, or imposed a penalty that is out of proportion to the conduct, arbitrators routinely substitute a lesser penalty.
The distinction between culpable and non-culpable conduct is the other organising principle on a discipline file. Culpable conduct — dishonesty, insubordination, safety violations, theft — is where the grievor has made a choice, and the just-cause analysis with its progressive discipline overlay applies. Non-culpable conduct — innocent absenteeism, capacity-driven performance shortfalls, medically rooted attendance problems — calls for a different framework altogether, focused on accommodation, rehabilitation, and the employer's ability to continue the employment relationship. Mis-classifying a file at intake — treating non-culpable absenteeism as if it were culpable misconduct — can collapse the employer's position at arbitration. Sertus tags discipline files by category on intake so counsel applies the right framework from the first step.
Investigation quality is usually the decisive factor. Arbitrators look for a thorough, fair, and timely investigation: was the grievor interviewed, were witnesses heard, were relevant policies followed, was union representation available where required, and did the employer treat comparable conduct consistently across the bargaining unit? A weak investigation can sink an otherwise defensible penalty, and a strong investigation with clear documentation can uphold a penalty that would otherwise look disproportionate. Sertus summarises investigation notes and witness statements automatically, so the strengths and weaknesses of the investigation are visible at a glance rather than buried in a folder of attachments.
How Sertus handles discipline files
Sertus is built by the co-author of Canadian Labour Arbitration(Brown & Beatty), so the platform understands how Canadian arbitrators actually assess discipline — not in the abstract, but in the same structured way an experienced advocate would.
- Progressive discipline doctrine: Did the employer move from lesser to greater penalties, and did the grievor get a meaningful opportunity to correct the conduct?
- Just and reasonable cause: Is there actually evidence the conduct occurred, and is the penalty proportionate to the offence?
- Quality of the investigation: Was the grievor interviewed, were witnesses heard, and were policies followed consistently?
- Culpability: Was the conduct wilful, reckless, or the product of circumstances outside the grievor's control?
- Mitigating factors: Long service, a clean record, the grievor's circumstances, and the overall context arbitrators weigh before sustaining the penalty.
- Pattern analysis across the bargaining unit: Sertus tracks discipline across the unit and highlights inconsistent application — a strong argument in an individual grievance and a useful input for bargaining strategy.
- AI case assessment: The AI reads the disciplinary letter, the grievance, and the collective agreement together and surfaces the strengths and weaknesses of the file before the first step meeting.
- AI-drafted step responses: Sertus prepares a first draft of the step response, linking back to the specific agreement article and the relevant facts from the record.
- Relevant agreement articles: Semantic search over the parsed collective agreement surfaces the clauses actually in dispute, not generic citations to “the agreement.”
- Deadline tracking: Every step in the grievance procedure is tracked against the agreement's own timelines.
