What the TTC Drug Testing Decision Teaches Us About Labour Arbitration

When most workers hear the word arbitration, they may think of a courtroom, lawyers, and complicated legal arguments. In the unionized workplace, labour arbitration is something different. It is one of the most important parts of the grievance process and, in many cases, the mechanism that allows a dispute between a union and an employer to receive a final decision from an impartial arbitrator.

The recent TTC random drug testing decision provides an excellent example of how arbitration works and why it matters to workers.

What is labour arbitration?

In a unionized workplace, a collective agreement establishes many of the rules governing the relationship between the employer and employees. When a union believes that an employer has violated the collective agreement, a grievance can be filed.

Not every grievance makes it to arbitration. Many disputes are resolved through discussions between the union and employer. But when the parties cannot reach an agreement, the grievance may eventually proceed to arbitration.

An arbitrator acts as an independent decision-maker who considers the evidence and arguments presented by the parties before issuing a decision. Depending on the circumstances, an arbitration hearing can involve witnesses, documents, expert evidence, legal arguments, and extensive cross-examination. The TTC drug testing case demonstrates just how complicated one arbitration can become.

A massive amount of evidence

The TTC case was not simply a disagreement about whether random drug testing was a good idea. The arbitrator considered evidence involving workplace safety, employee privacy, scientific testing methods, cannabis, cocaine, oral-fluid testing, and whether random testing could actually accomplish the safety objectives claimed by the employer.

The decision was hundreds of pages long, and numerous experts provided evidence regarding oral-fluid testing. That illustrates something important about arbitration: the decision is based on evidence. An arbitrator does not simply decide which side has the better argument. The parties have an opportunity to present their evidence and explain why the arbitrator should accept their position.

The collective agreement matters

One of the most important things for union members to understand is that the collective agreement is not simply a document that determines wages and vacation. It establishes rights and obligations for both employees and employers.

In the TTC case, the arbitrator considered whether the random testing program was a reasonable exercise of management rights and whether it complied with the collective agreement. That is an important lesson for union representatives. When an employer introduces or changes a workplace policy, the question is not necessarily just: “Can the employer do this?”

• What does the collective agreement say?
• What rights does management have?
• Are there limits on those rights?
• Is the policy reasonable?
• Does other legislation apply?
• What evidence supports the employer’s position?

Those questions can ultimately become central issues in arbitration. They are not the same questions used in a discharge case. Discipline still runs on the Wm. Scott questions. The TTC fight was a policy and management-rights case. Use the test that matches the issue.

Why the TTC decision matters

Arbitrator Laura Trachuk ultimately found that the TTC’s random testing program was not a reasonable exercise of management rights and violated the collective agreement. The arbitrator also found a violation of employees’ rights under section 8 of the Canadian Charter.

It is important not to oversimplify the decision. The award does not mean that every form of workplace drug or alcohol testing is prohibited. The arbitration specifically dealt with the TTC’s random testing program and its particular circumstances. Other forms of testing, such as reasonable-cause or post-incident testing, were not challenged in the same way in this arbitration.

What can union members learn from this?

The TTC case is a reminder that arbitration can be a powerful tool for resolving workplace disputes. It also demonstrates why union representatives need to investigate grievances carefully, understand the collective agreement, and build their cases around evidence.

Sometimes the issue is not simply what happened. It is why it happened, how it happened, what the collective agreement says, what evidence exists, and whether the employer’s actions were reasonable. Those questions can determine whether a grievance has a strong case.

The bottom line

Labour arbitration may seem complicated, but at its core it provides a way for unresolved workplace disputes to receive an independent decision. The TTC random drug testing case is an excellent example of how a workplace policy can lead to a complex arbitration involving collective bargaining rights, management rights, privacy, science, and workplace safety.

For workers and union stewards, understanding arbitration is important because the grievance process does not necessarily end when an employer says no. Sometimes, that’s where the next stage begins.
