The Growing Cost of Delayed Workplace Conflict

In Ontario workplaces, delay is often what turns a manageable conflict into an expensive one. The province’s labour relations system gives unionized parties structured tools for early resolution, including conciliation, grievance mediation, and grievance arbitration, but those tools only help if the parties use them before the conflict hardens.

The cost difference can be significant. A federal government evaluation summarized by Justice Canada notes that grievances can cost as much as $40,000 per file from the first level to a final adjudicated decision, while the average cost of mediation can range from $4,000 to $5,000. That same evaluation found that informal conflict resolution is valued because it preserves relationships, resolves issues faster, and reduces stress.

The growing cost of conflict is not just about legal fees. Burnout is still a major workplace pressure point: a 2025 Canadian workplace mental health report found that 39% of Canadian employees reported feeling burnt out, up from 35% in 2023, and estimated burnout costs employers $5,500 to $28,500 per employee annually depending on role. In other words, delayed conflict does not stay contained. It affects morale, productivity, attendance, and retention.

That is why workplace conflict tends to get more expensive the longer it sits. Formal processes are slower, more adversarial, and more resource-intensive than early, interest-based resolution. The Ontario government’s own grievance mediation process exists because not every workplace dispute should be pushed straight into arbitration.

For employers, unions, and employees, the lesson is simple: unresolved conflict rarely stays small. It becomes a relationship problem, then an operational problem, and eventually a legal one. Mediation cannot solve every file, but it can create the conditions for a practical conversation before positions harden and the cost of getting to yes rises sharply. That is often where the real value lies.
