Organized 1939

The International Union of Operating Engineers, Local Union No. 12 was consummated by an executive order of the General President of the International Union of Operating Engineers and approved by the General Executive Board on March 1, 1939.

Throughout the 84 years, the Officers of Local 12 have worked hard to see that the members receive a fair wage, overtime, paid holidays, subsistence pay, health and welfare, burial fund, vacation, pension and annuity benefits.

Local 12 leads the way to the next generation of skilled construction professionals.  We have established training sites in six different locations throughout Southern California and Southern Nevada to train apprentices and retrain journeypersons. Each training site is equipped with various updated equipment with highly qualified instructors.

Our purpose is to provide our well-established contractors with highly qualified members willing to work hard.

With the efforts of all operating engineers, we have created a better world and our members continue to dedicate themselves to improving an even better tomorrow.
