Running the company
The Skilled Trades Shortage Isn't Just a Hiring Problem. It's a Knowledge Problem.
The skilled trades shortage is usually described as a hiring problem: not enough people to fill open jobs. For most contractors, it's also a knowledge problem. When experienced people leave, they take years of know-how with them, and new hires can't learn it from someone who's no longer there. Capturing what your best people know, while they're still on the job, is part of solving the shortage.
You've seen the headlines. Associated Builders and Contractors estimates the construction industry needs about 349,000 new workers in 2026, and says most of that demand comes from people retiring, not from growth. The usual response is to focus on recruiting: job fairs, referral bonuses, partnerships with trade schools. All of that matters. But it only addresses half the problem.
What actually leaves when experienced people leave
When a 25-year lead retires, you don't just lose a pair of hands. You lose the way he lays out a wall so it's right the first time. The checks he makes before calling something done. The mistakes he catches on other people's work before an inspector does. What each GC, inspector, and regular customer expects.
Very little of that is written down anywhere. It lives in his head, and it reaches only the crew members who happen to work next to him.
Why hiring alone doesn't fix it
Say you do find a good replacement. They know the trade. What they don't know is how your company does the work. In the past, they'd pick that up over a few years of working next to someone experienced. But the experienced people are exactly the ones who are leaving. Across the skilled trades, the people who would have taught the next generation are retiring at the same time the next generation is arriving.
So new hires learn from whoever is available that week. Sometimes that's your best lead. Sometimes it's someone who picked up bad habits somewhere else. Your quality starts to depend on who rode with whom.
Treat know-how like an asset
Contractors protect their equipment, their bonding capacity, and their reputation. The know-how of their best people deserves the same attention. A practical way to start:
- List the people whose know-how matters most. Not just the ones close to retiring. Anyone who could take another job, move, or get hurt.
- For each, list the two or three tasks they do best. The ones that cause problems when someone else does them.
- Get each task down in their words. How we do it here, what people get wrong, and how you know it's right. A one-page questionnaire works, and a short phone video helps if they're willing.
- Have them check it. The goal is how they actually do it, not a rough version.
- Turn it into training every new hire takes. Before they reach the crew, in the language they understand best, with a quick check at the end.
What changes when the know-how stays
When your best people's methods are captured, a new hire can learn how your company does the work in their first week, instead of over years. Your leads spend less time repeating the basics and more time checking work in the field. And when someone does retire or move on, the next person starts with the same lessons instead of from scratch.
It won't fill an open position. But it means the people you do hire get up to speed faster, and the know-how that built your reputation doesn't leave with the next retirement.
Start before the next person leaves
The easiest time to capture how your best people work is while they're here and things are calm. Pick one person and one task this month. It's a small step, and it's one recruiting can't replace.
