What is this right?
You have the legal right to join a union and take part in lawful union activities. Your employer cannot interfere with, dominate, or try to influence the formation of a union.
The Canada Industrial Relations Board (CIRB) handles union certification. To certify a union, the CIRB needs to see majority support from workers and typically processes applications within 30 days.
Once a union is certified, both your employer and the union must bargain in good faith. Unfair labour practices — like punishing workers for union activity — are illegal.
When does it apply?
- All federally regulated employees.
- Managers and people in confidential labour relations roles may be excluded from the bargaining unit, but they still cannot be punished for supporting a union.
What to Do If Your Canadian Employer Retaliates Against Union Activity
- If your employer retaliates against you, file an unfair labour practice complaint with the CIRB. Call 1-800-575-9696.
- Document any anti-union conduct by your employer — notes, emails, witness names.
- If your union isn't representing you fairly, you can file a duty of fair representation complaint with the CIRB.
What should you NOT do?
- Don't organize on company time or using company equipment — do it on your own time and with your own devices.
- Don't assume employer anti-union campaigns are legal. Threats, promises, or surveillance to discourage union activity are unfair labour practices.
- Don't sign documents renouncing your union rights — those are not enforceable.
- Don't confuse a legal strike with a wildcat walkout. A strike is only legal after the collective bargaining process has been followed and a strike vote is held.
How Alberta differs from federal law
Unionization in Alberta workplaces is governed by the Labour Relations Code, RSA 2000, c. L-1, administered by the Alberta Labour Relations Board (ALRB).
- Alberta uses a mandatory vote system for union certification. At least 40% of employees in the proposed bargaining unit must sign union membership cards, then a secret ballot vote is held. A majority of those who vote must vote in favour for the union to be certified.
- The vote must be held within 5 days of the certification application being filed — one of the shortest timelines in Canada, designed to reduce employer interference during the campaign period.
- Employers cannot interfere with union organizing, threaten workers, change working conditions to discourage unionization, or fire or discipline workers for union activity. These are unfair labour practices under Part 2 of the Labour Relations Code.
- The ALRB can certify a union without a vote as a remedy if the employer has committed unfair labour practices serious enough to prevent a fair vote.
- Once certified, the union and employer must bargain in good faith. Alberta law gives workers the right to strike after the collective agreement expires and a government-supervised strike vote is held, with a majority of all employees in the bargaining unit voting in favour.
Additional Steps in Alberta
