What type of fraud is it called when two or more employees conspire to steal from a company?

When two or more employees conspire to steal from a company, the act is classified as collusion. This involves a secret agreement between parties to accomplish an illegal or deceitful act, such as diverting company assets for personal gain. In a collusive scenario, the cooperation between the involved employees typically allows them to circumvent internal controls and detection measures set by the organization, making the act of theft more sophisticated and harder to uncover.

Embezzlement refers specifically to the theft or misappropriation of funds placed in one's trust or belonging to one's employer, which usually involves a single individual rather than a conspiracy of multiple employees. Forgery involves the falsification of documents or signatures with the intent to deceive, while insider trading pertains to the buying or selling of stocks based on non-public, material information about a company. These concepts, while related to financial misconduct, do not capture the essence of the collaborative theft depicted in the question.
