Employee Fraud – Dealing With & Preventing Workplace Fraud

Employee fraud costs UK businesses millions every year, with £571.7 million stolen through unauthorised fraud in the first half of 2024 alone. Beyond financial losses, fraud erodes trust, disrupts operations, and damages reputations.

But fraud isn’t inevitable. Businesses that understand the risks, recognise red flags, and act early can prevent it before serious harm occurs.

In this article, we’ll explore exactly why employees commit fraud, common risk factors, key warning signs, and practical steps to prevent fraud in the workplace.

To help organisations strengthen their defences, our expert-created fraud prevention e-learning course equips teams with the knowledge to identify red flags, mitigate risks, and safeguard your business with confidence.

What is Employee Fraud?

Employee fraud refers to any intentional deception, theft, or dishonest activity carried out by an employee to gain financial or personal benefits at the expense of their employer. Unlike external fraud, which involves outsiders targeting a business, workplace fraud comes from within, which can make it very hard to detect.

Fraud in the workplace can occur in any industry, at any level of an organisation, from junior staff to senior executives. It can range from small-scale policy violations – such as exaggerating expenses – to major financial crimes, like falsifying company accounts.

While fraud may seem like an isolated issue, it’s more common than many businesses realise. Without proper oversight, even trusted employees can exploit gaps in financial controls, security protocols, or company policies.

Common Types of Employee Fraud

Employee fraud takes many forms, each with significant financial, operational, and reputational consequences. Below are the most common types, and how they occur.

Payroll Fraud

Payroll fraud happens when employees manipulate payroll systems to receive unauthorised wages, often in businesses with weak oversight.

Examples:

  • Ghost Employees – Fake employees on payroll diverting salaries to fraudsters.
  • Falsified Hours – Employees clock in/out inaccurately, sometimes with help.
  • Inflated Overtime – Claiming extra hours never worked.
  • Unauthorised Pay Adjustments – Employees increasing their own salaries.

Expense Fraud

Expense fraud happens when employees falsify or exaggerate business-related expenses to receive personal reimbursement.

Examples:

  • Personal purchases disguised as business expenses.
  • Altered receipts to inflate claims.
  • Double-Dipping – Submitting the same expense multiple times.
  • Split transactions to bypass approval limits.

Asset Misappropriation

Theft or misuse of company resources for personal gain, often involving physical assets.

Examples:

  • Theft of inventory or equipment.
  • Company credit card abuse.
  • Unauthorised use of vehicles or machinery.
  • Cheque tampering – forging or altering payments.

Financial Statement Fraud

Financial statement fraud involves the intentional manipulation of financial records to present false or misleading information. This can often involve executives or financial officers who have direct control over financial reporting.

Examples:

  • Revenue Inflation – Recording fake sales.
  • Concealing Liabilities – Hiding debts or losses.
  • Fake Invoices – Diverting funds via fraudulent transactions.
  • Inventory Manipulation – Overstating stock values.

Data Theft & Cyber Fraud

This involves employees stealing, selling, or misusing company data and exploiting digital vulnerabilities.

Examples:

  • Selling Trade Secrets to competitors.
  • Insider Trading – Leaking financial data for stock market advantage.
  • Hacking Systems for financial or operational manipulation.
  • Phishing Scams compromising sensitive information.

Procurement & Vendor Fraud

Procurement fraud happens when employees collude with external vendors to manipulate purchasing decisions for financial gain.

Examples:

  • Kickbacks – Receiving personal incentives for awarding contracts.
  • Fake Vendors – Creating fraudulent suppliers for payouts.
  • Overpricing Agreements – Inflating contract values for personal gain.
  • Product Substitution – Delivering low-quality goods while charging for premium ones.

The Fraud Triangle – Why People Commit Fraud

Understanding why employees commit fraud is key to preventing it. Criminologist Dr. Donald Cressey’s Fraud Triangle outlines three core factors that drive fraud: Pressure, Opportunity, and Rationalisation. Recognising these factors helps businesses identify risks and strengthen fraud prevention.

1. Pressure – The Personal or Professional Motivation to Commit Fraud

Pressure arises when employees face financial, personal, or workplace stressors that push them toward fraud.

Common Sources of Pressure:

  • Financial Struggles – Employees facing personal debt or financial hardship may see fraud as a way to relieve their burden.
  • Addiction Issues – Gambling, substance abuse, or other addictive behaviours can drive individuals to commit fraud.
  • Work-Related Pressure – Unreasonable sales targets, performance expectations, or job insecurity can tempt employees to falsify numbers or manipulate reports to meet demands.
  • Lifestyle Inflation – Some employees live beyond their means and resort to fraud to maintain an expensive lifestyle.

Real-World Example: A finance employee with credit card debt alters invoices and diverts small amounts into their account, believing they’ll “pay it back later.” As their debt grows, so does the fraud.

2. Opportunity – The Ability to Commit Fraud Without Immediate Detection

Fraud occurs when employees spot weaknesses in company systems that allow them to act without detection.

Common Workplace Opportunities That Enable Fraud:

  • Weak Internal Controls – Lack of financial oversight, audit trails, or transaction monitoring.
  • Lack of Supervision – Employees who handle finances, payroll, or procurement alone are more likely to manipulate records.
  • Excessive Trust in Employees – Businesses that never question financial reports or receipts create an environment where fraud can flourish.
  • Poor Cybersecurity Measures – Weak passwords, outdated systems, and lack of access controls enable employees to commit data theft or cyber fraud.

Real-World Example: A payroll employee inflates their salary over several months. With no audits in place, the fraud remains undetected until an external review.

3. Rationalisation – Justifying Fraudulent Behaviour

Even when employees feel pressure and have the opportunity, they often justify their actions to ease guilt.

Common Rationalisations for Workplace Fraud:

  • “I Deserve This” – Employees believe they are underpaid, undervalued, or unfairly treated, using fraud as a form of personal compensation.
  • “I’m Just Borrowing It” – Some convince themselves that they’ll pay the money back later, never intending to commit long-term fraud.
  • “Everyone Else Does It” – If fraud is common within a company (e.g., employees frequently submit exaggerated expense claims), individuals may feel it’s acceptable.
  • “The Company Can Afford It” – Employees who believe their employer is wealthy or engages in unethical practices themselves may feel justified in committing fraud.

Real-World Example: An executive inflates financial reports to meet investor expectations, telling themselves it’s temporary and will balance out later.

How Businesses Can Break the Fraud Triangle 

Fraud prevention requires disrupting one or more sides of the Fraud Triangle. Companies can take several actions to reduce the likelihood of employee fraud:

Reducing Pressure:

  • Provide financial wellness support and employee assistance programmes.
  • Set realistic performance targets to prevent stress-driven fraud.

Eliminating Opportunity:

  • Enforce dual approval for financial transactions.
  • Conduct regular audits and fraud risk assessments.
  • Restrict access to sensitive financial data based on job roles.

Challenging Rationalisation:

  • Promote ethical company values and fraud prevention training.
  • Enforce zero-tolerance fraud policies at all levels.
  • Implement whistleblower programmes for anonymous reporting.

Risk Factors for Fraud

Fraud can happen in any business, but certain workplace conditions make it more likely. Identifying and addressing these risk factors can significantly reduce fraud exposure.

1. Weak Internal Controls

Lack of clear financial procedures, oversight, or security creates opportunities for fraud.

Common Weaknesses:

  • No separation of duties, allowing one person full control over transactions.
  • Payroll loopholes, enabling false wage claims or ghost employees.
  • No audits, letting fraud go undetected for years.
  • Unrestricted access to financial data, increasing theft risks.

Prevention: Enforce segregation of duties, conduct regular audits, and use AI-driven fraud detection tools.

2. Rapid Growth & Poor Oversight

Fast-growing businesses prioritise expansion over fraud controls, leading to security gaps.

Key Risks:

  • Weak hiring processes, increasing the risk of employing fraud-prone individuals.
  • Inconsistent financial policies, leading to poor oversight.

Prevention: Set fraud policies early, conduct background checks, and monitor financial activity in new divisions.

3. Remote Work & Digital Fraud

Fraud risks have evolved with remote work, data theft, and cybersecurity threats.

Common Issues:

  • Easier data theft, with employees accessing sensitive files remotely.
  • Weak cybersecurity, increasing phishing and hacking risks.
  • Falsified work hours or expense claims.

Prevention: Use multi-factor authentication, enforce cybersecurity training, and track work hours transparently.

4. Toxic Workplace Culture & High Turnover

A negative work environment fuels resentment, low morale, and unethical behaviour.

Risk Indicators:

  • High dissatisfaction – disengaged employees may justify fraud.
  • Lack of trust between staff and management.
  • Frequent turnover, making long-term fraud harder to detect.
  • Unethical leadership, setting a poor example.

Prevention: Foster transparency, encourage whistleblowing, and recognise employee contributions.

5. Lack of Fraud Awareness & Training

Employees unaware of fraud risks, red flags, or reporting channels are unlikely to stop misconduct.

Why This Increases Risk:

  • Employees unintentionally participate in fraud due to ignorance.
  • Fraud goes unnoticed because staff fail to recognise warning signs.
  • Fear of retaliation discourages reporting.

Prevention: Enrol your team in our fraud prevention course to equip them with the confidence to identify fraud, report misconduct safely, and foster a culture where speaking up is the norm.

Signs of Fraud: How to Spot Potential Fraudulent Behaviour

Fraudsters work hard to cover their tracks, making fraud difficult to detect until serious damage is done. Recognising red flags and patterns of suspicious behaviour is key to preventing fraud before it escalates.

1. Unexplained Financial Discrepancies or Missing Assets

Financial irregularities often signal fraud. If accounts don’t balance, funds go missing, or inventory levels are off, further investigation is needed.

Warning Signs:

  • Records don’t match actual revenue or expenses.
  • Frequent write-offs to cover missing funds.
  • Unexplained invoices or payments to unknown vendors.
  • Disappearing stock or equipment.

2. Employees Refusing to Share Duties or Insisting on Handling Financial Tasks Alone

Fraudsters often resist oversight to avoid detection. If an employee refuses to delegate or reacts defensively when questioned, it could be a red flag.

Red Flags:

  • Refuses to take leave, fearing discovery.
  • Controls multiple financial processes without oversight.
  • Becomes secretive or aggressive when asked about records.

3. Sudden Lifestyle Changes – Living Beyond Their Means

A sudden increase in spending beyond an employee’s means can indicate fraud, especially when combined with other suspicious actions.

What to Look For:

  • Unexplained purchases of luxury cars, property, or vacations.
  • Frequent extravagant spending inconsistent with salary.
  • Sudden large cash deposits or multiple new credit cards.

4. Unusual Behaviour, Secrecy, or Defensiveness

Fraudsters may become nervous, withdrawn, or evasive when questioned, often delaying audits or withholding information.

Behavioural Warning Signs:

  • Avoids answering financial questions or providing documents.
  • Sudden shift in attitude – becoming secretive or aggressive.
  • Frequent excuses for missing records.

5. Frequent Complaints About Salary or Unfair Treatment

Employees who feel undervalued may justify fraud as compensation for perceived mistreatment.

Indicators of Fraud Risk:

  • Expresses resentment toward management over pay.
  • Claims the company “owes them” or they are “underpaid.”
  • Regular requests for salary advances or financial help.

What Should You Do If You Suspect Employee Fraud?

If you notice one or more of these warning signs, it’s crucial to take action immediately. Here’s what businesses can do to handle potential fraud cases:

1. Conduct an Internal Investigation

  • Review financial records, emails, and transaction logs for discrepancies.
  • Assign an independent investigator or external auditor to assess the situation.
  • Monitor employee behaviour and document irregularities.

2. Strengthen Internal Controls

  • Implement checks and balances to prevent employees from handling financial processes alone.
  • Conduct random audits and reconciliations to detect fraud early.
  • Restrict access to financial and sensitive data to only necessary personnel.

3. Implement a Confidential Whistleblowing Programme

  • Allow employees to report fraudulent behaviour anonymously.
  • Ensure that whistleblowers are protected from retaliation.
  • Promote a culture of transparency and accountability.

Why Spotting Fraud Early is Crucial

The earlier fraud in the workplace is detected, the less damage it can cause to a business. By recognising suspicious behaviour, enforcing stronger financial controls, and encouraging employees to report wrongdoing, organisations can significantly reduce their exposure to fraudulent activity.

Stop Employee Fraud Before It Costs You

Fraud can drain your finances, damage your reputation, and break the trust you’ve built – but only if you let it. The greatest risk is doing nothing until it’s too late.

Businesses that act early detect risks before they escalate, strengthen internal controls, and empower employees to prevent fraud at every level. Prevention is about control, confidence, and securing your company’s future.

Our fraud prevention training course equips your team to identify red flags, reduce risks, and safeguard your business.

Take action now – prevention is always stronger than reaction.
