Your Mission Is Our Mission

The Sheet Metal Workers’ International Association is a labour union serving, protecting and raising the living standards of skilled men and women workers employed throughout the United States, Canada and Puerto Rico in the construction, manufacturing, railroad and shipyard industries. We strive to establish and maintain through signatory employers desirable working conditions and thus provide for our members and their families that measure of comfort, happiness, and security to which every person is entitled in return for his or her labour from a deep sense of pride in our trade through a fair day’s work for a fair day’s pay.
