IUOE Celebrates 125 Years!


By December 7, 2021

IUOE celebrates their 125-year anniversary today!

It was on December 7, 1896 in Chicago, IL where 11 steam boiler engineers formed the National Union of Steam Engineers of America. In 1897 the first Canadian workers joined the fledgling union and to reflect this expansion across the border, the name was changed to the International Union of Steam Engineers. The steam gauge is still used on the logo today to honour the history.

As members began working with internal combustion engines, electric motors, hydraulic machinery and refrigerating systems, as well as steam boilers and engines, the word “steam” was dropped from the union’s name and in 1928 it became the International Union of Operating Engineers.

We are proud to be a part of IUOE history!
