The International Union of Operating Engineers (IUOE) is a progressive, diversified trade union that primarily represents operating engineers who work as heavy equipment operators, mechanics, and surveyors in the construction, pipeline, and mining industries, and stationary engineers who work in operations and maintenance in building and industrial complexes. IUOE also represents nurses and other health industry workers, public employees in a wide variety of occupations, and a number of job classifications in the petrochemical industry. Founded in 1896, the IUOE is dedicated to advancing the economic interests, safety, and well-being of its members through collective bargaining, training, and advocacy.
Serves as the primary administrative, legislative, policy-making, and organizational hub for the union, coordinating activities and support for local unions across the United States and Canada.
