A field crew runs on people who are hard to find and harder to replace. The bill for losing one is not the job ad. It is the truck that runs a man short, the job that slips, the licensed work that has to wait for someone qualified, and the years of site knowledge that walk off with a journeyman. Here is the field benchmark the data supports, how far it swings by role, and why a shrinking, aging trade pool makes each loss cost more than it used to.
Trades turnover is less about a high quit rate and more about a thin replacement pool. Replacing a field worker commonly runs one-half to two times annual pay once recruiting, onboarding, lost production, and the ramp to full output are counted, and the figure climbs sharply with a license or specialty. With median pay around $61,000 to $64,000 for electricians, plumbers, and HVAC technicians, that is roughly $30,000 to $125,000 a departure depending on the role. Average tenure in construction is only about four years, and more than one in five workers is over 55, so each exit lands in a market where the next qualified hire is hard to find. Those are honest planning ranges, not dollar-exact figures.
In an office, a vacant seat is mostly lost productivity. On a job, a missing tradesperson is schedule risk with a cost attached to every day it lasts. The work still has to get done, so the hours move somewhere: overtime for the crew that stays, a subcontractor brought in at a premium, or a slipped completion date that carries its own penalty. None of those shows up as a recruiting expense, and all of them are real money.
The replacement market is the part that makes the trades distinct. The country is short hundreds of thousands of construction workers, with one widely cited estimate putting the 2026 gap above 500,000, and the people aging out are not being replaced fast enough. More than one in five construction workers is over 55. So a single exit is not just a backfill, it is a search in a market where qualified candidates are scarce and tenure is short, which is why a field opening can sit unfilled for weeks while the work piles up.
The other field-specific cost is licensing and liability. A licensed electrician, plumber, or HVAC tech cannot be swapped for a helper, because the law and the inspection will not allow it. When the qualified person leaves, the work that requires that license stops until someone else can sign for it. The departure that looks like an hourly replacement can become a stalled permit, a failed inspection, or a callback, and counting only the recruiting cost misses the part that hurts most.
The most durable replacement-cost benchmark, used across industries and cited specifically for construction, is one-half to two times the worker’s annual pay, scaling with specialization and seniority. Applied to current BLS median wages, electricians at about $63,000, plumbers at about $64,000, and HVAC technicians at about $61,000, that puts a single field departure between roughly $30,000 and $125,000 once recruiting, onboarding, lost production, and ramp time are counted. A helper or laborer sits near the bottom of that band; a licensed journeyman or specialty tech sits near the top.
The driver is scarcity, not churn for its own sake. Tenure in construction averages about four years, among the shortest of any major industry, so the workforce turns over faster than in most sectors even when the quit rate cools. And the replacement is hard: electrician roles are projected to grow far faster than the average for all jobs while too few apprentices enter to fill them. Where the cost bites hardest is the licensed seat that also takes years to train.
The easiest seat to leave for a dollar more at another site, and the fastest to refill on paper. Each exit still runs toward one-half of annual pay once recruiting, onboarding, and the ramp to useful output on a crew are counted. The real cost is the supervision time a green hire pulls off a foreman.
Lower churn, far higher cost, often one to two times annual pay or more. Long to recruit, long to license, and they take site history, code knowledge, and customer relationships out the door. A single licensed gap can stall the work that legally requires that license until someone else can sign for it.
The costliest field departure. A good foreman holds a crew together, runs the safety routine, trains the apprentices, and keeps the job on schedule. Losing one raises churn beneath them and puts the completion date at risk, so the cost compounds across the whole job, not just the one seat.
Borrowed ranges are a starting point. The figure that moves a budget conversation is the one built from your own pay, fill time, and coverage cost. The build is simple: take the loaded hourly cost of the role, add the recruiting and onboarding spend, add the overtime or sub cost the gap forces while the seat is open, and add the lost or delayed production until the new hire is productive on a crew. For a journeyman around $30 an hour, that math commonly lands well into five figures once the weeks-long fill time and ramp are honest.
Multiply by your annual exits and the standing cost becomes visible. A shop that loses a handful of field workers a year, normal at four-year average tenure, is carrying a six-figure annual churn cost without ever seeing it as a line item. The point of the number is not precision to the dollar. It is to make the preventable share large enough that someone decides to act on it.
Across industries, employees themselves say a large share of voluntary exits, around 42 percent in recent surveys and about half in Gallup’s work, could have been prevented. In the trades the preventable causes are concrete: pay that trails the shop across town, no clear path from apprentice to journeyman to lead, schedules that wreck home life, and a foreman who never runs a real check-in. When the work itself is similar from employer to employer, the things that keep a tradesperson are predictability, respect, and a visible future, not just the hourly rate.
The apprentice window is where you have the most room to act. A trainee who is mentored, given a wage-step path, and kept past the first year becomes the journeyman you cannot hire on the open market, because there are not enough of them. Growing your own is slower than poaching, but in a market short hundreds of thousands of workers it is the only supply you control. The cheapest tradesperson to keep is the one you already trained.
Field turnover tracks the work. It climbs when a job wraps and a crew is between projects, when the weather turns, and when a competitor staffs up for a big award and poaches to fill it. Shops that plan around predictable attrition, with a bench, a pipeline of apprentices, and retention conversations before a job ends, keep more of their crew than shops that scramble to rehire every spring.
Treating turnover as a standing operating cost, tracked like job cost or safety, is what separates shops that manage it from shops that chase labor. Fill time by trade, turnover by crew, and first-year apprentice retention are workforce numbers worth watching, because they move before the schedule does.

The one-half to two times annual pay replacement band is a widely used cross-industry benchmark applied here to current trade wages; per-role cost splits are directional and modeled from the wage and tenure data above. Treat them as planning ranges and calibrate against your own role mix, license requirements, and local wage competition. These figures move; the date each was checked is shown above.
The more useful number than a single quit rate is tenure: construction averages about four years, among the shortest of any major industry, so the workforce turns over faster than most sectors even when quits cool. Paired with a labor shortage above 500,000 workers for 2026 and more than one in five workers over 55, each exit lands in a market where the next qualified hire is hard to find.
The standard benchmark is one-half to two times annual pay, scaling with specialization and seniority. At current BLS median wages, around $61,000 to $64,000 for electricians, plumbers, and HVAC techs, that is roughly $30,000 to $125,000 a departure once recruiting, onboarding, lost production, and ramp time are counted. A helper sits near the bottom; a licensed journeyman or specialty tech sits near the top.
The pool is shrinking. The country is short hundreds of thousands of construction workers, the people aging out are not being replaced fast enough, and licensed roles take years to train. A licensed seat also cannot be filled by a helper, because the law and the inspection will not allow it, so the work that requires that license stops until someone qualified can sign for it.
When the work is similar from employer to employer, what keeps a tradesperson is predictability, respect, and a visible future, not only the hourly rate. A clear apprentice-to-journeyman-to-lead path, schedules that protect home life, a real onboarding, and a foreman who runs honest check-ins move retention more than a one-time bump. Growing your own apprentices is the supply you control.
