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 Manitoba differs from federal law
Unionization in Manitoba is governed by the Labour Relations Act, CCSM c. L10, administered by the Manitoba Labour Board.
- Manitoba 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.
- The Manitoba Labour Board can certify a union without a vote as a remedy if the employer has committed unfair labour practices that made a fair vote impossible.
- Employers cannot interfere with union organizing, threaten workers, change working conditions to discourage unionization, or discipline workers for union activity. These are unfair labour practices under the Act.
- Once certified, the union and employer must bargain in good faith. Manitoba law gives workers the right to strike after the collective agreement expires and required steps (including conciliation) are completed.
- If the parties cannot reach a first collective agreement, either side can apply to the Manitoba Labour Board for first contract arbitration.
