Why is turnover so high in the trades — and what the rate actually is

The number, up front.

About 4% of construction workers leave their employer every month — roughly 48% a year — against about 3.3% monthly, or 40% a year, across all industries. That's per the U.S. Bureau of Labor Statistics' Job Openings and Labor Turnover Survey. Translated: a trades business turns over close to half its field team a year, about a fifth more churn than the average American employer. That's not a people problem — it's a system problem, and it's fixable.

Worth separating two things the headline number hides. Total separations include layoffs, seasonal ends, and firings, which construction has a lot of. Voluntary quits run about 1.8% a month, or roughly 21% a year — that's the slice you actually control through pay, leadership, and onboarding.

(You'll see 68% and 73% quoted widely for trades turnover. Those numbers circulate through staffing-industry blogs without a traceable primary source, and they don't match what BLS actually reports. We use the BLS figures.)

What's actually driving it

1. A market where everyone has another offer. Demand is outpacing the pipeline — the BLS projects about 40,100 HVAC openings and about 44,000 plumbing openings every year this decade, most of them replacing people leaving the trade. Good techs are never short on options. Loyalty has to be earned, not assumed.

2. Hiring in a panic. When a truck is sitting idle, owners hire the first warm body. A rushed hire is a poor-fit hire, and poor-fit hires leave (or get fired) fast — which re-opens the seat and restarts the panic.

3. "Figure it out" onboarding. A tech who's handed keys and a van with no real first-90-days plan never feels like they belong. People don't quit jobs they feel part of; they quit jobs where they feel disposable.

The compounding problem

Each driver feeds the next. Turnover thins your bench, which makes the next opening more urgent, which forces a rushed hire, which raises turnover again. Most trades businesses are stuck in this loop and blame "this generation" instead of the loop itself.

How to get below the average

• Hire for fit, not for speed. The only way to do that is to not be desperate — which means keeping a pipeline of pre-screened candidates so an opening is a choice, not an emergency.
• Own the first 90 days. Structured onboarding is the single highest-leverage retention move. A tech who feels competent and welcomed at day 90 usually stays.
• Measure it. If you don't know your own turnover rate, you can't tell whether anything you change is working.

The bottom line

Running 8 points above the national average isn't the cost of doing business in the trades — it's the cost of hiring reactively. And the 21% who quit voluntarily are the ones worth fighting for: those are your trained techs choosing to leave, not seasonal roll-off. Break the panic-hire loop with a steady pipeline and a real onboarding plan, and you can run below the industry average instead of above it.

The levers that actually move it are in how to retain HVAC and plumbing techs — and if your instinct is to fix it with money, why raises don't fix retention problems is worth reading first. Every exit also resets the clock on a 56-day hiring cycle and the cost of a bad replacement hire.

That pipeline is exactly what we build and maintain for plumbing and HVAC businesses, so good hires stop walking out the back door as fast as they come in the front.
