Termination Grievances

Handle unjust-dismissal grievances from discharge through arbitration with AI that reads the collective agreement and the disciplinary record together.

What a termination grievance actually needs

Termination is the heaviest penalty in the labour relations toolkit, and Canadian arbitrators apply a demanding just-cause standard before upholding a discharge. A termination file has to account for every part of that standard — not just the incident the employer relied on, but the history that led up to it, the investigation that followed, and the remedy the grievor is asking for.

The doctrinal architecture is straightforward to state and exacting to apply. The arbitrator asks, first, whether the conduct the employer relies on actually occurred, on a balance of probabilities. Second, whether that conduct — on its own and in the context of any discipline history — was serious enough to justify some form of discipline. Third, whether discharge specifically, as opposed to a lesser penalty, was proportionate given all the circumstances: length of service, the grievor's prior record, the quality of the employer's investigation, any mitigating factors, and how the employer has treated comparable conduct by other employees. Canadian arbitrators regularly substitute a lesser penalty even where the underlying conduct is proven, because the proportionality question is separate from the question of whether something happened.

The culminating-incident doctrine is the other piece of the architecture that shapes how these files are built. Where the discharge is the product of a disciplinary history and a final triggering event, the employer must establish both the underlying record and the culminating incident itself. A weak record on either side of that equation — a missing warning, a skipped step in progressive discipline, a thin investigation of the final incident — can collapse the case on the proportionality question. That is why termination files are evidence-heavy and why preparation time typically exceeds hearing time by a wide margin. Sertus is built to compress the preparation side of that equation without reducing the quality of the record.

Remedies on a successful termination grievance span a wide range, and the choice among them is usually the hardest question on the file. Reinstatement with full back pay is the default remedy where the grievance succeeds outright. Reinstatement with a lesser penalty — a substituted suspension — is common where the arbitrator finds the underlying conduct proven but the discharge disproportionate. Compensation in lieu of reinstatement is awarded where the employment relationship is beyond repair, often measured by reference to common-law notice periods and the specific circumstances of the bargaining unit. And last-chance agreements, with conditions attached, are a negotiated middle ground that both sides sometimes prefer to a full arbitration outcome.

How Sertus handles termination files

Sertus is built by the co-author of Canadian Labour Arbitration(Brown & Beatty), the reference text Canadian arbitrators cite, so the AI analysis is grounded in the arbitration standards that actually matter on a termination file.

  • The just-cause standard: Did the conduct actually occur, was it serious enough to warrant discharge, and was discharge proportionate in the circumstances?
  • Progressive discipline record: Was the grievor given fair warning that their job was at risk, or did the employer skip steps the agreement or past practice requires?
  • Seniority and service: Long service is a mitigating factor in Canadian arbitration. The grievor's date of hire and disciplinary history belong on the case from day one.
  • Discipline history, parsed: Sertus reads the full disciplinary record for the grievor and identifies gaps in the employer's progressive discipline — missing warnings, skipped steps, or inconsistent application across the bargaining unit.
  • AI case assessment: The AI reads the termination letter and the collective agreement together and surfaces the strengths and weaknesses of the file before counsel opens it.
  • The culminating incident: The specific event that triggered the discharge — what it was, when it happened, who witnessed it, and how the employer documented it.
  • Quality of the investigation: Was the grievor interviewed, were witnesses heard, were policies followed? A weak investigation can sink an otherwise defensible discharge.
  • Remedy: Reinstatement with full back pay, reinstatement with a lesser penalty, compensation in lieu, or a last-chance agreement — the arbitrator has the full range.
  • Precedent search: The decision library lets you pull comparable arbitration awards on the same conduct and the same agreement clause, so the remedy analysis is grounded in actual outcomes.
  • Deadline tracking: Every step of the grievance procedure is tracked against the agreement's own timelines, with alerts before the arbitration referral window expires.
  • Evidence summarisation: Investigation notes, witness statements, CCTV logs, and employer policies are summarised automatically and attached to the case record.
