Which of the following is an example of employee-related fraudulent activity?

Claiming for expenses not incurred is an example of employee-related fraudulent activity because it involves the dishonest portrayal of business expenses. When an employee submits a claim for expenses that they have not actually incurred, they are misrepresenting their financial actions for personal gain. This type of fraud undermines the integrity of the financial reporting process and can lead to financial losses for the organization.

In the context of the other activities, completing tasks ahead of schedule, volunteering for extra shifts, and participating in team-building activities do not involve deceit or misrepresentation. These actions are typically viewed positively within an organization, as they reflect productivity, commitment, and teamwork, rather than any form of fraudulent behavior. Thus, only the act of falsely claiming expenses aligns with employee-related fraud.
