Germany: Legal limits on employee surveillance and monitoring

Under GDPR and German labor law, employer surveillance of employees is subject to strict limitations regarding transparency, purpose, and proportionality. While employers are permitted to conduct occasional, sample-based checks and are legally required to record working hours to ensure compliance with rest periods, continuous or systematic monitoring is generally considered legally problematic.

Legal precedents, including rulings by the Federal Labor Court, indicate that even if surveillance is conducted improperly, the resulting evidence may still be used to justify a dismissal if the employee committed a serious, intentional breach of duty, such as theft or intentional time fraud. However, employers who conduct secret surveillance without a specific cause act unlawfully and may face high fines from data protection authorities or claims for damages from employees.

Furthermore, the introduction of technical systems—including those used for cybersecurity like multi-factor authentication—often triggers the co-determination rights of works councils. Under the Works Constitution Act, works councils must be involved if a system is objectively capable of monitoring employee behavior or performance, regardless of whether the employer intends to use it for that purpose.
