The most reliable way to prevent employee theft is to remove the opportunity, raise the odds of getting caught, and make the consequences clear before anything goes wrong. In practice that means five things working together: careful hiring, written policies, separated financial duties, regular inventory checks, and physical security such as access control and CCTV. This guide walks through each, then covers warning signs and what to do if you suspect someone.
TL;DR
- Theft by staff is an opportunity problem. Limit who can reach cash, stock, keys and data, and keep a record of who did.
- Hire carefully, put your theft policy in writing, and have employees sign that they received it.
- Split financial duties, count inventory at random, and have someone other than the stock handler verify the numbers.
- Access control and CCTV deter theft and give you evidence when something goes missing. Tell employees they are in place.
- A red flag is a reason to look, not proof. Document facts, avoid confronting anyone, and involve counsel and police.
Why employee theft is easy to miss
Outsiders trip alarms. Employees have keys, codes and trust. That is why internal theft often goes on for months before anyone notices.
The Association of Certified Fraud Examiners’ 2026 Report to the Nations analyzed 2,402 occupational fraud cases across 143 countries and territories. Its examiners estimate that organizations lose more than $5.5 trillion to fraud, about 5% of projected global wealth. Fraud covers more than shoplifting-style theft, but the lesson carries over: losses are large, and they come from people with legitimate access.
The North Carolina Department of Public Safety describes employee theft broadly. It includes larceny, skimming, fraudulent disbursements, embezzlement of raw materials or inventory, and even stealing business opportunities. So a good prevention plan covers cash, stock, equipment, data and time, not just the till.
Start with hiring and written expectations
American Family Insurance calls hiring honest employees the first line of defense, best done with pre-employment screening that digs into job history and references.
AIG’s employee theft prevention checklist goes further. It recommends comprehensive screening reviewed by legal counsel and, depending on how important or sensitive the job is, criminal and credit checks. Match the depth of the check to the access the role carries. A stockroom lead or bookkeeper warrants more than a floor greeter.
Then set the rules down in writing:
- Write a security procedure that explains what happens to an employee caught stealing.
- Give every employee a copy and collect a signed statement of receipt.
- Post a notice that dishonesty will not be tolerated and offenders will be dismissed.
Both insurers describe these steps, and AIG notes that selective hiring, a clear no-tolerance message and detection procedures usually lead to lower theft levels. Have an employment attorney review the wording, because rules on termination and background checks differ by state.
Build financial and inventory controls
Physical security helps, but most internal theft is caught by numbers. AIG’s checklist points to controls over petty cash, bank deposits and withdrawals, checks, payroll, bank-statement reconciliation and invoice payments, plus separation of financial responsibilities. If one person can approve, pay and reconcile, nobody is watching.
A simple framework:
| Area | Control | Why it works |
|---|---|---|
| Cash handling | Count at register close with a second person; deposit on a schedule | Skimming needs a gap between sale and deposit |
| Payroll and invoices | Different people approve, pay and reconcile | No single person can create and hide a payment |
| Inventory | Scheduled and random counts, verified by someone other than the stock handler | Shortages surface fast and cannot be self-reported away |
| Receiving and shipping | Match incoming goods to purchase invoices and outgoing goods to shipping documents | Paper trails expose diverted stock |
| Discounts and benefits | Written employee discount policy | Removes gray areas that excuse small thefts |
The NC DPS guidance supports several of these: monitoring cash register activity, a clear employee discount policy, and accurate inventory checked regularly by someone other than the person responsible for it.
Count more often than you think you need to
An annual count tells you how much you lost, not who or when. Random spot counts tell employees that stock is being watched. ASIS Foundation’s research on workplace dishonesty lists spot audits and counts alongside CCTV exception monitoring and hotlines as parts of a prevention and response program.
Learn from the people doing the work
In audits, conversations with the people who run a process often reveal how controls are really applied versus how they are written. This guide on audit evidence from employee interviews explains how interviews support reliable findings. The same approach helps when you review your own stockroom, cash office or receiving dock for weak spots.
Use access control to limit who can reach what
The NC DPS recommends strict key control for premises, storerooms and display areas. Keys are hard to track. They get copied, lent and lost, and a physical key never records who used it.
Modern access control fixes that. Each employee gets a card, fob or phone credential tied to specific doors and hours. If a storeroom is short on Tuesday, you can see which credentials opened the door. Practical steps:
- Map your high-value areas: stockrooms, cash offices, server rooms, loading docks, tool cribs and pharmacy or chemical storage.
- Give access by role, not by seniority: only those who need a door should have it.
- Use individual credentials: shared codes cannot identify anyone.
- Remove access the day someone leaves: this is the cheapest control on the list.
- Review access logs: look for after-hours entries and repeated entries to areas outside someone’s job.
Badge identification for employees and visitors is also recommended in both the AIG checklist and the American Family Insurance guidance. They add that, where feasible, employees should enter and leave through a single monitored entrance.
If you are planning a system, our pages on commercial access control installation, key fob and key card solutions and mobile access control show what is available. If you already have CCTV or alarms, access control system integration lets door events and video line up on one timeline.
Use CCTV to deter theft and document what happens
CCTV does two jobs. It discourages theft when staff know cameras are there, and it gives you objective footage when something is missing. Case IQ advises placing cameras to cover break rooms, warehouses and stock rooms, and cash registers, and locking up high-value tools, cash and medicines.
AIG and American Family Insurance both recommend supervising shipping and receiving with CCTV, since that is where goods leave the building legitimately and illegitimately. ASIS also notes that purse and package checks should be applied consistently, with the reasons made clear.
Some placement priorities:
- Cash handling points, with a clear view of hands and the drawer.
- Stockrooms and storage cages, at the door and over the shelving.
- Loading docks, receiving and shipping areas.
- Employee exits and parking areas where goods could be moved.
- Trash and recycling areas, since the NC DPS flags trash and empty boxes as concealment routes.
Tell employees about the cameras. A hidden camera catches a thief. A visible one often prevents the theft, which is the better outcome. Check your state’s rules on recording, particularly audio, with your attorney before installation.
For larger or multi-site operations, remote CCTV monitoring means someone is watching when you cannot, and video analytics can flag unusual activity such as movement in a storeroom after hours rather than leaving you to scrub through hours of footage. Warehouses and distribution centers have their own challenges, covered in our guide to warehouse CCTV and security.
A three-step loop: diagnose, prescribe, test
ASIS Foundation describes a countermeasure process in three parts. It is a useful way to avoid buying equipment first and thinking second.
- Diagnose. Look at CCTV footage, shrinkage data, audits, incident reports, peer reports and surveys. Where are losses actually happening?
- Prescribe. Choose controls that raise the perceived risk of being caught and reduce access and freedom of movement in the problem areas.
- Test and refine. Use counts, sales data, camera footage, incident reports and employee feedback to see whether losses fell. Adjust.
The same ASIS report calls employees reporting suspicious or unethical behavior by coworkers one of the highly effective techniques. Telephone hotlines and incentive or award systems help encourage it. A confidential reporting channel costs little compared with the losses it can surface.
Warning signs: reasons to look, not proof
The ACFE has found that 84% of perpetrators showed at least one behavioral red flag before detection, according to a summary of its findings. The same source stresses that a red flag is a reason to look closer, not evidence of wrongdoing.
Common patterns worth a second look:
- Process signals: frequent voids, refunds, write-offs or stock adjustments processed by the same person.
- Inventory signals: shrinkage that clusters on certain shifts, or counts that never reconcile.
- Access signals: door entries at odd hours, or repeated access to areas outside the person’s duties.
- Control avoidance: reluctance to share duties or take time off, or insistence on handling a task alone.
Every one of these has innocent explanations: training gaps, a busy shift, a flawed system. Treat the pattern as a prompt to check records and footage, not to accuse.
If you suspect an employee is stealing
How you respond matters as much as what happened. Case IQ’s guidance on handling suspected employee theft warns that acting too fast, or without documentation, can expose a company to litigation. It recommends strong evidence, with video preferred and witnesses as a backup, and a chain of custody showing the evidence was not altered.
A sensible sequence:
- Do not play detective. Keep the circle small and avoid confrontation until you have facts.
- Preserve evidence. Save footage, access logs, transaction records and inventory counts with dates and times. Write down who handled what.
- Document facts, not opinions. “Register 2 recorded six voids between 6 and 7 p.m.” is evidence. “She seems shady” is not.
- Talk to counsel. An employment attorney can tell you how your state’s rules affect interviews, termination and recording. Case IQ notes the federal Employee Polygraph Protection Act governs lie detector tests, which is one reason to check before improvising. For general orientation, see this overview of employment legal advice.
- Involve law enforcement. Report suspected theft to your local police department rather than trying to solve it yourself.
Can an employee be fired for stealing? In most cases dismissal is a standard consequence, and written policies make it easier to apply fairly. Details depend on your state and any contract or union agreement, so confirm with an employment attorney before you act.
Perspective: our view on employee theft
Most businesses treat employee theft as a trust problem. We see it as a design problem. When one person can open a storeroom, move stock and leave without a record, even a good employee is being tested every day.
The strongest programs we plan combine layers: access control that records who goes where, CCTV placed over cash points, stockrooms and docks, and monitoring that gets noticed when no one is on site. Each layer covers gaps in the others, and together they give you records that are fair to employees and to you.
We design these systems around each site rather than from a template, because a cold-storage warehouse, a school and a solar farm leak in completely different places. The goal is to protect assets and keep honest employees above suspicion.

FAQ
How do you prevent employee theft in the workplace?
Combine screening at hire, written policies signed by employees, separated financial duties, random inventory counts, and physical controls like access control and CCTV. No single measure is enough. The layers work because each closes a gap in the others.
What evidence is needed to prove employee theft?
Strong evidence is objective and documented: video footage, access logs, transaction records and inventory counts, kept with a clear chain of custody. Witness statements can support it. Your attorney and local police can tell you what is needed for discipline or prosecution.
Should employees know about security cameras?
Yes. Cameras that employees know about deter theft before it happens, and a signed policy shows expectations were clear. Place them over cash points, stockrooms and docks, and confirm your state’s recording rules with an attorney.
Does a warning sign mean an employee is stealing?
No. Odd hours, frequent voids or reluctance to take time off can all have innocent causes. Use them as a prompt to review records and footage, and avoid accusing anyone until the facts support it.
