I.U.O.E. Local 501, AFL-CIO was formed in 1953 by the merger of several regional locals. Since its humble beginnings Local 501 has grown to one of the largest Stationary Engineer Locals in the entire United States. Over the decades our Local has established itself as a pillar of highly trained, multi-skilled trade unionists throughout the Labor community. Our members perform maintenance and repair of all HVAC equipment, boiler operation, lighting, plumbing, welding, painting, carpentry, or in general, all trade related maintenance and repair. We take pride in not only representing a diverse group of individuals, but also helping that group continue to advance their skills through training and acquiring the knowledge necessary to advance through their careers. Our Local represents Operating Engineers from all over Southern California and Southern Nevada: from State of California employees to major hospitals, hotels, high-rises, casinos. dairies, production facilities, performance halls and arenas to name a few. By becoming a member of Local 501, an engineer begins the first steps in gaining security, skills, and opportunities for him/herself and their family. We hope that you will become a member, take an active role in your Local and participate in many of the activities and meetings that we hold throughout the year. The staff and members of Local 501 welcome you and we hope you'll take the time to browse our websites to learn more about us. We welcome you to the start of a very good career.
