What We Do

Our Values

Embracing Inclusivity: Our Commitment to a Discrimination-Free Environment

At SMART 18, we wholeheartedly embrace a culture of inclusivity. Discrimination, harassment, hazing, or bullying is strictly forbidden within our membership. We stand resolutely against any form of prejudice or bias based on race, color, religion, age, creed, national origin, sex, gender, sexual orientation, gender identity or expression, marital/parental/family status, veteran’s status, disability, or any other legally protected class.

Strength in Diversity: Building a Stronger, More Competitive Workforce

SMART 18 recognizes the profound value of diversity within the workforce. We firmly believe that diversity not only strengthens our union but also enriches our communities and enhances the competitiveness of the sheet metal and transportation industries. Our mission is to transform the perspectives of management, labor leaders, and our members alike. We strive to actively recruit, warmly welcome and ardently retain the most proficient and skilled workforce available, all while celebrating the beautiful tapestry of differences in age, ability, ethnicity, gender identity, national origin, language, marital status, political affiliation, race, religion, sexual orientation, and all the other characteristics that make each individual uniquely remarkable.
