Our union, the Sheet Metal Air Rail Train International Association (SMART) and our contractors, the Sheet Metal and Air Conditioning Contractors' National Association (SMACNA) have a long history of close cooperation in apprenticeship, training, and education. Both agree that this important industry needs to attract the best possible apprentices on the basis of talent, interest, and aptitude for the work. The strength of the industry reflects this positive attitude. Union and contractors getting along--another reason for you to consider a career in sheet metal--learning while you work!
