Laborers are the first trade on a job site and usually the last to leave. They set up traffic control before a road is torn open, dig and shore trenches, place concrete, run the compactor, and clean up after everyone else. In the union world, that work belongs to LIUNA, the Laborers' International Union of North America. If you are looking at a LIUNA apprenticeship, this guide covers what the work is, what the pay data says, how a typical construction craft laborer apprenticeship is structured, and the training that separates a general laborer from a specialist.
What LIUNA construction laborers actually do
The Bureau of Labor Statistics describes construction laborers, also called construction craft laborers, as working in every phase of a project. Typical tasks include cleaning and preparing sites, loading and unloading materials, building bracing and scaffolding, digging trenches, compacting earth, and running hand and power tools. On road crews, laborers may specialize in traffic control, pavement breakers and jackhammers, or surveying equipment. With extra training, some handle explosives or hydraulic boring machines.
LIUNA's own regional sites show how wide the range is. The New Jersey Laborers list roads, bridges, tunnels and transit; broadband and water infrastructure; building construction, demolition and renovation; power plants and substations; and pipeline support work. Their skills list includes pipelaying, concrete placement, erosion control, rough terrain forklift, hoisting and rigging, and even wind turbine erection and solar panel installation.
That is the key point about laborers: it is the most flexible entry trade. You touch almost every phase of construction, which makes it a strong base whether you stay a laborer for life or later move toward another craft.
Construction laborer vs. helper: why the difference matters
BLS groups laborers and helpers together, but they are different jobs. A helper assists one specific trade, such as an electrician's or plumber's helper. A construction laborer has a craft of its own, with its own scope of work, its own apprenticeship and, in the union world, its own international union.
The pay data reflects this. BLS reports a median of $47,120 a year for construction laborers (May 2025), versus figures in the low $40,000s for most types of helpers. The category of all laborers and helpers came in at $46,680, or $22.44 an hour, with the bottom 10 percent under $34,820 and the top 10 percent above $76,400. One more detail stands out: laborers placed through temporary help agencies had a median of just $35,740. That gap is a big part of the argument for getting into a structured program instead of picking up day work through a staffing agency.
As with any BLS figure, these numbers mix union and nonunion workers and leave out benefits. Union laborers' compensation also includes health and pension contributions, so compare total packages using our union money guide.
How a LIUNA apprenticeship is structured
LIUNA apprenticeships are run by regional and state training funds, so details differ. The New Jersey program is a useful, well-documented example of the model:
| Item | New Jersey Construction Craft Laborer Apprenticeship |
|---|---|
| Length | About 3 to 4 years to journeyworker |
| On-the-job training | 4,000 hours |
| Classroom training | 400 hours |
| Pay progression | 60%, 70%, 80%, then 90% of the journeyworker rate, rising roughly every 1,000 hours |
| Cost | Free to qualified candidates; apprentices are paid while training |
| Prior experience | Not required; credit may be given for experience you already have |
The minimum qualifications listed there are typical: age 18 or older, a valid driver's license, a passed drug test, the physical ability to do the work, and the ability to read and write English. Note what is not on that list. The New Jersey page does not mention a diploma or GED requirement, and BLS says no formal education credential is typically required for laborers, though employers may prefer a diploma. Other regions set their own rules, so check the program in your state.
One practical warning: many programs open applications only at certain times. When we checked, the New Jersey page said it was not taking applications and pointed people to a sign-up list for announcements. If your local is closed, get on the notification list and use the wait to earn certifications.
Training that turns a laborer into a specialist
The LIUNA Training and Education Fund says it offers more than 50 courses, with classes in every U.S. state and Canadian province, and that training is free for members. Named areas include hazardous materials remediation, remote tunneling and concrete work.
For your career, these specialties matter because they decide which jobs you get dispatched to. A laborer with only general skills competes with everyone. A laborer who can handle the jobs below has a shorter list of competitors:
- Trenching and excavation safety and confined space. Both appear in the New Jersey skills list and come up constantly on utility and water work.
- Hazardous materials remediation. Environmental cleanup and abatement work requires specific training before you can be on site.
- Pipelaying and concrete placement. These are core heavy civil skills and steady sources of work.
- Hoisting, rigging and rough terrain forklift. These make you more useful on building sites.
- Tunneling. Specialized, often tied to large transit and water projects.
BLS adds that employers often require OSHA safety certification, either before or after hiring, and lists rigging and scaffolding as optional credentials. If you are waiting for an application window, OSHA 10 is the cheapest, quickest thing you can do to look serious.
Job outlook: one of the faster-growing construction trades
BLS counted 1,489,300 construction laborer jobs in 2025 and projects 7 percent growth through 2035, faster than average for all occupations. Across laborers and helpers combined, it expects about 137,000 openings a year, mostly from people leaving the field.
The breakdown is telling. Most helper categories are projected to be flat or shrinking, while construction laborers are expected to add about 109,000 jobs. The infrastructure work that laborers dominate, including roads, water, broadband and energy, is the reason. If you want a trade that is gaining jobs rather than just replacing retirees, laborers are a good bet.
The safety reality of laborer work
Be clear about this going in. BLS states that construction laborers have one of the highest rates of injuries and illnesses of any occupation. The common causes are slips, falls and contact with objects or equipment. Work is outdoors in all weather, sometimes at height or in confined spaces, and highway and bridge crews may work overnight to avoid traffic. In northern states, winter can cut hours sharply.
This is one place where union training earns its keep. Trench, confined space and traffic control training are the difference between a crew that goes home and one that does not. Treat every safety class as career training, not paperwork, and speak up when something looks wrong. If you are ever disciplined for raising a safety issue, the grievance process exists for exactly that.
Laborer as a career or a stepping stone
Plenty of people spend a whole career as laborers and move up to foreman or superintendent. Others use the trade as a way in. BLS notes that some carpenters and some masons start out as construction laborers and helpers before moving into those crafts. Working beside other trades every day gives you a clear view of what each one does, which makes your next choice an informed one rather than a guess.
If you think you might switch later, keep a record of your hours, the equipment you have run and the certifications you have earned. Credit for prior experience is common in apprenticeship programs, and documented hours are what count. Our guide to proving union trades experience covers how to do that well.
Either way, the LIUNA card is not a dead end. With specialties such as pipelaying, tunneling or hazmat work, laborer can be a full career in its own right.
Is a LIUNA apprenticeship right for you?
Use this quick checklist:
- You are fine working outdoors, in heat and cold, and with physically demanding tasks.
- You would rather learn many parts of construction than master one narrow skill right away.
- You have, or can get, a driver's license and pass a drug test.
- You are willing to keep stacking certifications after you are in.
- You can handle some seasonal slowdowns, especially in colder states.
If most of those are true, laborers are one of the most accessible ways into union construction. The education barrier is low, the training is free, and the work is growing.
Bottom line
Verdict: LIUNA is the most open door into union construction, with low entry requirements, free training and a job category BLS expects to grow 7 percent. The trade-off is physical risk and seasonal hours. Get in through a registered apprenticeship rather than temp agencies, then specialize early in trenching, hazmat, pipelaying or tunneling so you are the laborer contractors ask for by name.
