You trusted someone for years. They ran your office or your yard, they knew where everything was, and then you found out they were quietly helping themselves to your materials, your labour, or your production time. Now you are staring at two ugly questions at once: do I press charges, and how did I let this happen for so long?
Employee theft in a trades business rarely comes from the new hire nobody trusts yet. It comes from the person you stopped watching because they earned it. That is exactly what makes it so damaging, and so common.
Why the person you trust most is the one who can hurt you
I have spent more than 20 years advising owners, most of them in construction and the skilled trades, and I have sat across from more than one owner working through this exact gut-punch. The pattern is consistent. The theft is not about a bad person slipping past your defences. It is about access without oversight.
Think about who has the keys to steal from you:
- The office manager who cuts the cheques and reconciles the accounts.
- The operations lead who orders materials and signs for deliveries.
- The long-tenured hand who knows which jobs get billed and which do not.
These are your positions of trust. They are also the seats where one person controls both the doing and the checking. When the same person records the transaction and verifies it, you do not have a control. You have a hope.
The three ways it usually shows up
In a trades or manufacturing shop, misappropriation tends to take one of three forms:
- Materials walking out the door, billed to a job or written off as waste.
- Labour or production capacity redirected to side work on your dime.
- Money moved through the books by the same person who reconciles them.
None of these need a criminal mastermind. They need an owner who is too busy to look.
Why it compounds if you ignore it
Here is the part owners underestimate. The financial hit is not the worst of it. The worst of it is what the missing controls do to the rest of your business over time.
When one person can misappropriate resources unchecked, your numbers are already lying to you. Your margin looks worse than it should and you cannot tell why. You start pricing off bad data, chasing revenue to cover a leak you cannot see. I have watched owners run themselves ragged trying to fix a margin problem that was really a theft problem.
There is a legal dimension too. Depending on how you handle the discovery, the termination, and any recovery, you can expose yourself to wrongful-dismissal or defamation risk if you move on gut feel instead of documented fact. This is where you slow down and get proper advice.
I am a business builder and leadership coach, not a lawyer. On the question of pressing charges, recovering losses, or terminating cleanly, talk to an employment lawyer and, if the loss is large, the police. Do not take legal steps based on a blog post, including this one.
The fix: separate the doing from the checking
You cannot prevent every bad actor. You can make it far harder to steal and far faster to catch. The principle is simple: no single person should control a transaction end to end.
Start with these:
- Split duties. The person who orders materials should not be the only one receiving them. The person who cuts cheques should not be the only one reconciling the bank.
- Read your cash off the bank, not just the accounting software. I have owners read cash flow straight from bank transactions, because the software shows what someone entered, and the bank shows what actually happened.
- Put a second set of eyes on reconciliations, even if that second set is yours, monthly.
Then close the two gaps where losses hide:
- Run a post-job review that ties materials and labour to the job that consumed them. Redos and mystery variances are where theft hides.
- Hire into positions of trust on evidence, not interview charm. When I help owners fill a trusted seat, we measure the candidate against the real demands of the role using a Person Profile assessment, weighting behaviours, driving forces, and competencies, so the decision rests on fit instead of gut feel.
Controls are not an insult to your good people. They protect your good people, because when something goes missing, a clean set of controls tells you fast that it was not them.
A word on rebuilding trust
After a betrayal like this, owners tend to swing to one of two extremes: trust no one, or pretend nothing happened. Neither works. The middle path is structure. You extend trust through a system, not through hope. Good employees welcome that, because it makes their honesty visible instead of assumed.
The counter-argument worth naming
Some owners will say controls slow them down and signal distrust to a loyal crew. Fair. A separation-of-duties system does add steps. The honest trade-off is this: a few hours a month of oversight against the cost of a leak you cannot see, running for years, on numbers you cannot trust. In every case I have worked, the oversight was cheaper.
You do not need enterprise software or a full finance team. You need the doing and the checking in different hands, and you need to look at your own bank statements.
One concrete next step
This week, pick one financial process where a single person controls it start to finish, most likely cheque-writing and bank reconciliation, and split it. Assign the reconciliation to someone else, or do it yourself, and compare it against the bank directly. If you want help building operations and controls that make theft hard and margin visible, that is the work we do with trades owners at Workplaces.
Build what compounds.
