Which of the following is not a required reporting action for employees?

The correct choice indicates that discussions about workplace changes are not a required reporting action for employees in the context of insider threat prevention and information security. While communication regarding workplace changes can be important, it does not directly relate to the safeguarding of classified information or adherence to security protocols. The other options involve actions that pose a direct threat to national security or the integrity of sensitive materials, hence they require immediate reporting to the appropriate authorities.

Employees are typically mandated to report any inappropriate copying of classified material, as it represents a serious breach of protocol. Similarly, unauthorized disclosure of classified information requires urgent action since it can lead to sensitive information falling into the wrong hands. Bypassing security rules or protocols also represents a significant threat to information security, making it crucial for employees to report such behavior promptly. In contrast, workplace discussions do not inherently threaten security and thus do not warrant the same level of concern or mandatory reporting.
