Which of the following options is incorrectly listed as types of employee fraud?

Teaming and leading is a recognized type of employee fraud where two or more employees work together to deceive their employer, often around processes or controls they exploit. This type of fraudulent activity can involve manipulating company systems or collaborating to approve unauthorized transactions.

Payroll fraud occurs when employees manipulate payroll systems to receive compensation they are not entitled to. This can include falsifying hours worked, creating ghosts on the payroll (employees that do not actually exist), or inflating salaries.

Purchase ledger fraud involves the manipulation of accounts payable records, typically by either inflating the prices of goods and services or creating false invoices. This method usually enables employees, especially those in accounting or finance, to embezzle funds by claiming payments for goods that were never received or services not rendered.

False billing fraud is typically considered a specific form of purchase ledger or billing fraud and may not be categorized separately in many contexts. However, within the framework of enumerating types of employee fraud, it may not always be distinctly recognized. Thus, while the other options represent established categories of fraud related to employees, the classification of false billing fraud often overlaps with broader categories, making it less precise as a standalone type.
