Operating Engineers Local 3 represents the interests of people who build and protect. Most of our 41, 000 members work as heavy equipment operators and construction workers, but we also represent public employees, such as maintenance workers and police officers. Our training program for construction professionals provides journey- and apprentice-level training that is second to none, while giving our signatory employers access to the highest skilled workers in the industry. Local 3's jurisdiction covers Northern California, Northern Nevada, Hawaii and Utah, and our membership makes us the largest construction trades local in the United States.
