OP&CMIA Local #143 at a Glance
Our Construction Workers Union knows that strength lies not only in the words we stand by, but most importantly through our actions and collective bargaining. Back in 1901, our founders realized that by working together we could overcome challenges much more efficiently, and that is why we ultimately decided to join forces as OP&CMIA Local #143.
