Frequently Asked Questions
Pre-Employment Polygraphs
What does a pre-employment polygraph test check?
A pre-employment polygraph goes beyond standard background checks by assessing a candidate’s honesty about:
- Previous dismissals
- Involvement in theft or fraud
- Undisclosed criminal activity
- Fabricated qualifications or experience
It helps employers build a more complete risk profile before hiring.
Can a background check miss important information about a candidate?
Yes. Background checks typically only reflect recorded criminal history.
They may not reveal:
- Internal disciplinary actions
- Dismissals without criminal charges
- CV fraud or exaggerated experience
This means a candidate can appear “clean” on paper while still posing a risk.
Why should companies use polygraph testing before hiring?
Because many workplace risks are not visible through traditional screening.
A polygraph can help identify:
- Integrity risks
- Dishonesty during interviews
- Hidden behavioural patterns
This is especially important for roles involving:
- Finance
- Stock control
- Operations
When should a pre-employment polygraph be conducted?
Best practice is to conduct polygraphs at the final stage of recruitment, after shortlisting top candidates.
This ensures:
- Cost efficiency
- Focus on high-value hires
- Better decision-making between equally qualified candidates
Does a polygraph replace a background check?
No, it complements it.
- Background checks verify documented history
- Polygraphs assess undisclosed risks and honesty
Using both together provides a more complete evaluation.
Are pre-employment polygraphs suitable for all roles?
No. They are most effective for:
- Mid to senior-level roles
- Positions of trust
- Roles involving money, assets, or sensitive information
What risks can businesses avoid with pre-employment polygraphs?
Businesses can reduce the risk of:
- Hiring candidates with hidden misconduct
- Internal theft or fraud
- Repeated behavioural issues from previous employment
Investigations
How do I know if employees are stealing from my business?
Unexplained stock losses, financial discrepancies, or irregular reporting are often early warning signs.
In many cases, theft is not random but organised, involving:
- Internal staff
- External suppliers or customers
- Manipulation of processes
A structured investigation is needed to identify the root cause and those involved.
What causes unexplained stock losses in a business?
Stock losses can be caused by:
- Internal theft (individual or organised)
- Supplier or customer collusion
- Manipulation of stock control systems
- Process inefficiencies or poor management oversight
A proper investigation is required to determine whether losses are due to fraud or operational issues.
How do companies uncover internal fraud?
Internal fraud is typically uncovered through a combination of:
- Investigations
- Polygraph testing
- Undercover operations
- Monitoring and evidence gathering
These methods help identify:
- Who is involved
- How the fraud is taking place
- Where systems are being exploited
What is the difference between theft and organised (syndicated) theft?
Theft usually involves individuals acting alone for small, repeated gains.
Organised (syndicated) theft involves:
- Multiple people working together
- Coordination with external parties
- Larger financial impact
Syndicated theft is often the cause of significant business losses.
What services do I need if I suspect fraud in my business?
Most clients don’t initially know what service they need.
The correct approach typically involves:
- Identifying the problem (investigation)
- Gathering evidence (undercover or monitoring)
- Verifying individuals (polygraph testing)
A tailored strategy is required based on the specific situation.
Should I start with a polygraph test if I suspect theft?
Not always.
Polygraphs can help identify where issues exist, but they do not provide full evidence.
In many cases, it is more effective to:
- Conduct an investigation first
- Gather supporting evidence
- Then use polygraphs as part of the process
What is the purpose of an undercover investigation?
An undercover investigation allows businesses to:
- Observe real behaviour without detection
- Identify internal collusion
- Understand how systems are being manipulated
It provides direct insight into what is happening inside the business.
Will an employee confess if questioned by an investigator?
Not usually.
Without strong evidence, most individuals will:
- Deny allegations
- Avoid responsibility
- Request proof
Confessions typically occur only after sufficient evidence has been gathered.
Why isn’t interviewing employees enough to prove misconduct?
Interviews alone rely on voluntary disclosure.
Without evidence:
- Individuals can deny wrongdoing
- There is no basis for action
Effective investigations require evidence before confrontation.
