About Us

Local 412 was founded in the early 1940's to represent the employees of engineering and jobbing shops in the Highland Park, Michigan area.  By the mid-1960's, largely a "white collar" union, it was composed of employees of the Chrysler Corporation's Engineering Staff of Highland Park, Engineering Staff Highland Park hourly rate, Highland Park Technicians and Defense Engineering Division.  Additionally it represented between 400 and 500 other members.  Today Local 412 is still one of the largest amalgamated locals with over 6500 active & retired members that is made up of salary, hourly, skilled trades and public sector employees.  These workers range from engineering and design in the automotive and defense industries, to attorneys in the public sector, to skilled tradespersons, to city workers and healthcare workers around SE Michigan.
