Fired for Union Organizing Activities in Ontario

Under the Ontario Labour Relations Act, firing an employee for participating in a union organizing drive is an Unfair Labour Practice (ULP). The Ontario Labour Relations Board (OLRB) has the power to heavily fine the employer, order immediate reinstatement, and mandate full back pay for the terminated worker.

The right to join or organize a trade union is a fundamental right protected by Canadian law. ✊ Unfortunately, when workers in cities like Hamilton, Oshawa, or Windsor try to form a union to improve their working conditions, some employers resort to illegal “union busting” tactics. Firing the key organizers in an attempt to spread fear and kill the union drive is one of the most serious offences an employer can commit under the Ontario Labour Relations Act, 1995.

When an employer terminates you during a union drive, the legal process is entirely different from a standard wrongful dismissal case. ⚖ Instead of just suing for severance pay at a standard courthouse, these disputes are aggressively handled by the Ontario Labour Relations Board (OLRB). The law places a “reverse onus” on the employer, meaning they must prove to the Board that anti-union sentiment played absolutely zero part in their decision to fire you. Partnering with a union representative or a specialized labour lawyer is crucial to fighting back.

Step-by-Step Process for Challenging a Union-Busting Termination

Time is of the essence when an organizer is fired. ⌛ The goal is usually to get the worker back on the job quickly to show the rest of the employees that the employer’s intimidation tactics will not work. Here is the standard procedure.

Step 1: Contact Your Union Organizer Immediately

If you were working with an established union (like Unifor, CUPE, or the Steelworkers) to organize your workplace, call your union representative the moment you are fired. 📞 Established unions have dedicated legal teams and massive budgets specifically designed to protect workers during organizing drives. They will typically handle the legal filings on your behalf at no cost to you.

Step 2: Filing an Unfair Labour Practice (ULP) Complaint

Your lawyer or union rep will quickly file an Unfair Labour Practice complaint with the OLRB. 📋 This application outlines how the employer violated the Labour Relations Act by using termination as a tool of intimidation. The OLRB takes these allegations very seriously and will expedite the file because a delayed response could permanently destroy the union organizing campaign.

Step 3: The OLRB Mediation Process

Shortly after the complaint is filed, the OLRB will assign a Labour Relations Officer (LRO) to mediate the dispute. 🤝 The LRO will meet with both the employer and the union/employee to try and reach a settlement. Settlements often involve the employer agreeing to reinstate the worker with full back wages, plus a promise to stop interfering with the union drive.

Step 4: The Expedited Board Hearing

If the employer arrogantly refuses to settle and insists they fired you for a “valid reason” (like suddenly caring that you were 5 minutes late last week), the matter goes to a formal hearing before the OLRB. 🖥️ Because of the reverse onus, the employer must testify first and prove their innocence. If the Board finds even a hint of anti-union motivation, they will rule in your favour.

How Much Does it Cost in Ontario?

Fighting a union-related termination is uniquely structured when it comes to legal fees. 💸

  • Union Coverage: If you are working with an official union to organize, their in-house legal counsel will almost always represent you for free.
  • Private Labour Lawyer: If you started a grassroots movement without a major union and need to hire a private lawyer, hourly rates typically range from $400 CAD to $800 CAD.
  • Contingency Fees: Some private lawyers may take the case on a contingency basis (taking 25% to 35% of a cash settlement), but this is less common if your primary goal is to get your job back.
  • OLRB Filing Fees: There is absolutely no fee to file an Unfair Labour Practice complaint with the Ontario Labour Relations Board.

How Long Does the Process Take?

Because union drives are highly time-sensitive, the OLRB moves much faster than standard civil courts. 📅 A mediation meeting is usually scheduled within 14 to 30 days of filing the complaint. If a full hearing is required, the Board will often issue a decision ordering reinstatement and back pay within 3 to 6 months, which is incredibly swift for the Canadian legal system.

Frequently Asked Questions (FAQ)

Do I have to tell my employer I was organizing the union?

No, union organizing is meant to be confidential until the official certification vote. However, if the employer finds out through rumours or surveillance and fires you, it is still an illegal reprisal under the Labour Relations Act.

What if they claim they fired me for performance issues?

The OLRB is very experienced at seeing through fake excuses. Because of the reverse onus, the employer must prove that union activity played absolutely a 0% role in your termination. If the Board finds the firing was even 1% motivated by anti-union bias, you win.

Can I just take a severance payout instead of getting my job back?

Yes. While the primary remedy is reinstatement, many workers do not want to return to a toxic, union-busting environment. During mediation, your lawyer or union rep can negotiate a lump-sum financial settlement in exchange for you agreeing to walk away.

Can the employer be punished beyond my compensation?

Yes. The OLRB can order the employer to post public notices in the workplace admitting they broke the law, allow union organizers onto company property, or in extreme cases, automatically certify the union without a vote as a penalty for severe intimidation.
