Internal theft (employee theft)
Internal theft (employee theft): Internal theft is loss caused by a retailer's own employees. It includes merchandise carried out the back door, cash and deposit theft, refunds processed with no sale behind them, and sweethearting at the register. Every control for it sits inside the building.
Internal theft is loss caused by a retailer’s own employees. Employee theft is the same thing. It includes merchandise carried out in an apron pocket or a back-room bag, cash and deposit theft, refunds processed with no sale behind them, and sweethearting at the register. It is the part of shrink that never comes through the front door.
Why it matters in a store
Internal theft is the source stores talk about least and control best, because every control sits inside the building: cash handling, voids and overrides, refunds, receiving, and a reporting route associates trust. Most of it is small and repeated rather than dramatic, so routine procedure catches more of it than any investigation. Training works when procedures and reporting are taught together. An associate who knows how a void is supposed to work is the one who notices when a coworker’s void does not look right, and a coworker who already noticed is the cheapest detection method a store has. The reporting route has to feel normal, not risky, and the store has to name who receives a tip and what happens next.
What the survey data shows
The National Retail Federation’s 2023 National Retail Security Survey defines internal theft as acts of theft committed by an employee, or in collusion with an employee by outsiders. For fiscal year 2022, retailers attributed 29% of shrink to employee theft, behind 36% to external theft. The same survey reported an average loss of $2,180 per internal theft investigation, in line with 2021 and 2020 levels. That is the size of one case, not a store’s annual loss, so use it to judge whether a single case is worth an investigation, not to size a program.
Two numbers circulate for how much loss is internal, and they measure different things. Employee theft alone was the 29% above. Retail Dive’s summary of the same survey said 63% of lost inventory has internal causes, with 36% from external theft, and that 63% adds process and control failures, errors, unknown and other losses to employee theft: the survey’s own split sums to it. Quote the 29% when the subject is theft by employees. It is also the most recent figure that series published, because after conducting annual research on shrink for more than three decades, the National Retail Federation won’t release a report on the issue this year, as Retail Dive reported in 2024.
What should a store manager do when they suspect an employee of internal theft?
Don’t confront, accuse or search the person on the floor. Write down what was seen: date, time, register or area, transaction numbers, and who else was there. Send it to whoever owns investigations, loss prevention or HR, and leave the questioning to them. Suspicion needs specifics, not opportunity. Federal polygraph rules make that point in their own context: access in the sense of possible or potential opportunity, standing alone, does not constitute a basis for reasonable suspicion, and routine inventory or cash register shortages would not meet the economic loss requirement either. A short count on one shift is a reason to check the process, not to name a person. If the associate is in a union, the NLRB describes the right of employees, upon request, to have their representative present during an interview that the employee reasonably believes could lead to discipline, and under current Board law, only union-represented employees have this right. The interview rules and polygraph limits are in employee theft investigations and employee rights.
Most cases surface through people. Across occupational fraud generally, not retail alone, the ACFE found that tips were once again the most frequently used detection method, accounting for 43% of cases. More than half of those tips came from employees, with more than twice as many tips coming from employees who received fraud awareness training. The register controls that catch it earlier are in how to reduce employee theft at the register.
How it shows up on the floor
- Register: unscanned items for a friend, discount overrides with no reason, a no-sale key opened between customers, a refund to a card the cashier controls.
- Cash office: a deposit that is short, or a drawer count that never balances on one person’s shift.
- Receiving: a case marked as received that never hit the shelf, or an adjustment logged by the same person who signed the truck.
- Back room: merchandise stacked by the door with no paperwork, or a personal bag that leaves heavier than it arrived.
