Our Commitment

Building better workplaces

CLAC is a union that was founded on the belief that people, businesses, and work communities flourish when workplaces are based on cooperation and mutual respect—when we work with each other, not against each other.

In the face of intense adversity from unions that saw workplaces as war zones, our founders set out to create a different kind of labour union.

Our commitment to building positive workplace communities and seeking win-win solutions still guides us today.

Welcome to a different kind of union. Welcome to CLAC.




We think differently than other unions.

We work to make your workplace a better place—so that you and your co-workers can grow both as a workplace community and as individuals.
