What is a “Construction Craft Laborer?”

Construction Craft Laborers' are members of the Laborers' International Union of North America and are skilled union construction workers who perform specific job duties in one or more of the following four general categories.

  • Commercial Construction
    A Laborer who works in this area of construction may tend carpenters, tend masons, place concrete or work on site preparation.

  • Highway Construction
    Laborers' working in this area of construction may work with operating engineers to get final grade, they may install underground drainage systems or place concrete or asphalt. Laborers' are also used to place barricades and direct traffic.

  • Underground Construction
    Laborers' working on an underground crew may install water distribution systems, natural gas distribution systems, sewer systems, storm drainage systems, telecommunication cable or work on tunneling projects.

  • Environmental Remediation
    In this category a laborer may remove asbestos, clean up hazardous waste sites, remove lead based paint or work on a nuclear power plant decommissioning project. Laborers' working in this category are required to be formally trained in the area in which they work and adhere to strict safety requirements.

About Us


Michigan Laborers’ Training and Apprenticeship Institute (MLTAI) is a non-profit training facility that is jointly administered by management and union labor.


There are four state-of-the-art MLTAI locations to serve the training needs of Michigan Laborers'. For addresses and other site information, please scroll to the bottom of the page.


For over forty years, Construction Craft Laborers' have been able to gain new skills or upgrade their current skills by attending classes at MLTAI. Laborers' who are new to the trade can acquire the necessary skills to enter the construction industry with a degree of confidence.


MLTAI offers this training to union Construction Craft Laborers' completely free of charge. In fact, Laborers' who attend training receive a travel allowance to help offset travel expenses.


It is the goal of MLTAI to satisfy the training needs of Construction Craft Laborers', Local Laborer Unions and Contractors alike. To accomplish this goal, MLTAI develops specific courses as needed, and if necessary will take the training to the Laborers' by way of satellite courses. The following example demonstrates MLTAI’s dedication to this goal.

When the time came to decommission the Big Rock Nuclear Facility in Charlevoix, Michigan Consumers Power Company had very specific and detailed training requirements for the crew of men and women who would be doing the work. MLTAI staff created a site-specific course that combined an oxy-acetylene cutting and burning class with a hoisting and rigging class. Consumers Power Company retained the responsibility of providing the Radiation Worker I and II training. A course, now in use, which includes all the training required for a laborer to work in a nuclear plant, is “Nuclear Power Plant Decommissioning.”

Other examples of MLTAI’s efforts include creating a site specific hazard recognition class for Laborers' going to work on General Motors demolition projects in Flint, Michigan and doing satellite classes at local union halls, jobsites and contractors yards.

MLTAI has consistently met the demands of an ever changing and more technical construction industry. Thanks to cooperation between union and management we will continue to meet these demands well into the future.
