Which of the following is true regarding employee monitoring under GDPR?

Employee monitoring under the General Data Protection Regulation (GDPR) must adhere to principles of proportionality and transparency. This means that any monitoring activities must be justified by a legitimate purpose and should not unnecessarily infringe upon the privacy rights of employees.

Proportionality ensures that the extent of monitoring is appropriate in relation to the objective it aims to achieve, for instance, enhancing security or ensuring compliance with laws. Transparency is crucial as it mandates that employees are informed about the monitoring practices, the purposes for which their data is collected, and how it will be used. This builds trust and allows employees to understand the extent and nature of the monitoring occurring in their work environment.

The other options either imply absolute restrictions or suggest invasive practices that go against GDPR principles. Therefore, adhering to the requirements of proportionality and transparency is essential in complying with GDPR while conducting any form of employee monitoring.
