SCCA is the leader in labor negotiations with the construction unions in Southern California, while working closely with other associations. This practice has resulted in our successful long-term relationship with the construction industry trades. SCCA acts not only as a source of information for our members, but also to the general construction industry. SCCA has major labor agreements with Operating Engineers, Laborers, Cement Masons, Carpenters, Iron Workers, and the Construction Teamsters.
