Investigating a loss without wrecking the team
A shrinkage investigation handled badly costs more in goodwill than the stock was worth.
Stock is missing and the possibility of theft has to be considered. How that consideration is handled determines whether the business ends up with better controls or with a demoralised team and the same problem.
Investigating unexplained loss is different from routine productivity oversight. If a business considers employee monitoring software as part of an investigation, it should define a narrow purpose, appropriate access controls and the rules that apply before collecting activity data.
Exhaust the boring explanations first
Before anyone is spoken to, the administrative causes should have been checked: receiving errors, unit-of-measure confusion, unrecorded internal use, adjustments, counting mistakes on both the current and previous counts.
This is not naivety. In most investigations that reach a conclusion, the answer is in that list, and having checked it first is what makes any subsequent conversation credible.
Introducing better recording as an improvement to accuracy is accurate and workable. Introducing it as a response to suspected theft poisons it, and the poison outlasts the investigation.
Apply controls to everyone, including owners
Controls that exempt management are read exactly as they appear. Where the rule is that stock movements are recorded, it applies to the person who takes something for a customer meeting as much as to anyone else.
For U.S. accounting context, IRS Publication 538 explains accounting methods and includes guidance relevant to inventories.
Be careful with monitoring
Cameras, bag checks and access logging are regulated in most jurisdictions, with requirements about notice, proportionality and purpose that differ by country. Covert monitoring of employees is unlawful in many places outside narrow circumstances.
Beyond the legal position, monitoring introduced in response to an unquantified suspicion tends to find nothing and to be remembered for a long time. Establish the size and category of the loss first.
If it is theft, handle it as a process
Where evidence points at an individual, that becomes a disciplinary and possibly a legal matter with its own requirements — notice, a hearing, representation — which differ by jurisdiction and are not something to improvise.
Take advice before acting. Investigations handled informally have a way of becoming employment claims regardless of what was actually taken.
Say what you found
Where an investigation concludes that the loss was administrative, tell the team. A team that knows it was suspected and never hears the outcome draws its own conclusions, and they are rarely favourable.
