Operating Engineers Local 49

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 industry, and stationary engineers, who work in operations and maintenance in building and industrial complexes, and in the service industries. IUOE also represents nurses and other health industry workers, a significant number of public employees engaged in a wide variety of occupations, as well as a number of job classifications in the petrochemical industry.

This representation is the core of IUOE’s mission. From ensuring protections of prevailing wages on public projects, to alleviating healthcare costs through coalition building, to improving our contractors’ competitiveness, IUOE has and will continue to be tirelessly dedicated to the common interests of its members.

Founded in 1896, IUOE today has approximately 400,000 members in 123 local unions throughout the United States and Canada. IUOE is the 10th largest union in the AFL-CIO. Over 100 state-of-the-art training and apprenticeship programs ensure that IUOE members are the safest, most productive, and highly skilled craft workers.

The IUOE Local 49, based in Minneapolis, has a business office in Mandan, N.D., and encompasses work throughout the state. Today we are more than 13,000 men and women in Minnesota, North and South Dakota with contracts for highway/heavy and building contractors, well drillers, equipment repair shops, welding shops, sand and gravel suppliers, counties, municipalities, hospitals, school districts, cemeteries, and more.
