Introduction

In 2025, unionized workers in Canada still form a significant portion of the workforce—over 30% of all employees according to Statistics Canada. With rising layoffs, organizational restructuring, and new labor laws rolling out, one question pops up frequently: Can union employees be fired in Canada?

While union protection offers more job security than non-union roles, it does not make workers immune to termination. However, the rules, processes, and employee rights involved are vastly different. If you're in HR, a unionized employee, or a company navigating collective agreements, this guide breaks it all down—legally, practically, and respectfully.

Let’s explore how termination works under a union environment, when exceptions apply, and what protections you truly have.

Why Collective Agreements Don’t Guarantee Job Immunity

A common misconception is that union workers cannot be fired. This is false. Collective agreements or union contracts do not forbid firing; rather, they establish clear procedures that must be followed before termination.

In Canada, firing a unionized employee requires:

  • Just cause — such as misconduct, repeated lateness, or insubordination

  • Following a progressive discipline process

  • Compliance with both labor laws and the collective agreement

It’s not a matter of if but how and when a union employee can be legally terminated.

What Constitutes Just Cause for Firing Union Employees?

To legally terminate a unionized employee, employers must prove just cause, which typically means:

  • The dismissal is proportional to the offense

  • Prior warnings or corrective steps were taken (except for very severe cases)

  • Consistency with how similar cases were handled in the past

Examples include:

  • Repeated safety violations

  • Theft or fraud

  • Chronic absenteeism

Employers must conduct a thorough workplace investigation, document all evidence, notify the union, and allow the employee to seek union representation.

Failing to follow these steps can lead to wrongful termination grievances, arbitration, or labor board complaints.

Can a Union Employee Be Fired Without Warning?

The question of firing without warning comes up often. The answer: rarely, and only for extreme misconduct, such as:

  • Workplace violence or threats

  • Theft or fraud

  • Severe harassment or discrimination

In almost all other cases, unions insist on a structured discipline path that includes:

  • Verbal warnings

  • Written notices

  • Suspensions

  • Finally, termination (if necessary)

This process protects both employee rights and employer accountability.

What About Strikes, Layoffs & Job Protection?

A frequent concern is: Can an employee be fired during a strike? Generally, no.

Canadian labor laws prohibit firing employees for participating in legal strikes. Employers who do so face penalties, including:

  • Sanctions from labor relations boards

  • Arbitration or court challenges

  • Orders for reinstatement with back pay

However, employees can be dismissed for misconduct during strikes, such as property damage or blocking entry.

What Happens After Termination of a Union Employee?

After termination, unionized workers have several avenues for recourse:

  • Filing a grievance through the union

  • Arbitration or labor board hearings

  • Potential reinstatement or financial compensation

  • Termination pay as defined by collective agreements (often different from non-union workers)

Additionally, employees may pursue constructive dismissal claims if their working conditions were significantly worsened without consent.

Essential Tips for HR and Employers Managing Unionized Staff

If you’re responsible for HR or management in a unionized environment, here’s a checklist to ensure legal compliance:

  • Review and understand the collective agreement

  • Maintain clear documentation of performance or conduct issues

  • Follow the progressive discipline process

  • Allow union representation during all disciplinary meetings

  • Ensure consistent application of policies across employees

  • Seek legal advice if uncertain

For official guidance, visit the Canadian Labour Relations Board or your provincial labor board.

Why Employee Letters and Documentation Matter

An important HR tool in union workplaces is the employee letter—used for:

  • Disciplinary warnings

  • Termination notices

  • Performance improvement plans

These letters must be:

  • Clear and professional

  • Shared with the union when applicable

  • Timely and consistent with previous actions

Learning how to write a job letter for an employee includes:

  • Including employee name and ID

  • Dates and facts of incidents

  • References to policies or agreements

  • Next steps or expectations

  • Contact information for HR

Neutral and factual tone is critical to avoid disputes.
