The General Data Protection Regulation (GDPR) does not prohibit surveillance of employees in the workplace. Still, it requires employers to follow special rules to ensure that the rights and freedoms of employees are protected when processing their personal data. The GDPR applies to any processing of personal data in the context of the activities of an establishment of a controller or a processor in the EU, regardless of whether the processing takes place in the EU or not. The GDPR also applies to the processing of personal data of data subjects who are in the EU by a controller or processor not established in the EU, where the processing activities are related to the offering of goods or services to data subjects in the EU or the monitoring of their behaviour as far as their behaviour takes place within the EU.
The GDPR requires that any processing of personal data must be lawful, fair and transparent, and based on one of the six legal grounds specified in the regulation. The most relevant legal grounds for employee surveillance are the legitimate interests of the employer, the performance of a contract with the employee, or the compliance with a legal obligation. The GDPR also requires that any processing of personal data must be limited to what is necessary for the purposes for which they are processed, and that the data subjects must be informed of the purposes and the legal basis of the processing, as well as their rights and the safeguards in place to protect their data.
The GDPR also imposes specific obligations and restrictions on the processing of special categories of personal data, such as biometric data, which reveal racial or ethnic origin, political opinions, religious or philosophical beliefs, or trade union membership, or which are processed for the purpose of uniquely identifying a natural person. The processing of such data is prohibited, unless one of the ten exceptions listed in the regulation applies. The most relevant exceptions for employee surveillance are the explicit consent of the data subject, the necessity for the purposes of carrying out the obligations and exercising specific rights of the controller or of the data subject in the field of employment and social security and social protection law, or the necessity for reasons of substantial public interest.
The GDPR also sets out the rules and requirements for the transfer of personal data to third countries or international organisations, which do not ensure an adequate level of data protection. The transfer of such data is only allowed if the controller or processor has provided appropriate safeguards, such as binding corporate rules, standard contractual clauses, codes of conduct or certification mechanisms, and if the data subjects have enforceable rights and effective legal remedies.
Based on the scenario, the only condition under which the surveillance system could be used on the personal devices of employees is if the employees give valid consent and the monitoring is narrowly limited to their professional tasks. This option is the most consistent with the GDPR’s principles and requirements, as it:
Is based on a valid legal ground for the processing of personal data, namely the consent of the data subject, which must be freely given, specific, informed and unambiguous, and which can be withdrawn at any time.
Is limited to what is necessary for the purposes of the monitoring, as it only covers the work-related activities and communications of the employees, and excludes the private or personal ones.
Is transparent to the employees, as it informs them of the monitoring and its precise scope, and gives them the opportunity to object or opt out of the monitoring.
Does not involve the processing of special categories of personal data, such as biometric data or data revealing political opinions or trade union membership, which are not necessary or proportionate for the purposes of the monitoring, and which do not fall under any of the exceptions listed in the regulation.
Does not involve the transfer of personal data to a third country, such as China, which does not provide an adequate level of data protection, and which may pose additional risks for the rights and freedoms of the employees.
The other options listed in the question are not valid conditions for using the surveillance system on the personal devices of employees, as they:
Are not based on a valid legal ground for the processing of personal data, as they either rely on the legitimate interests of the employer, which are not balanced with the rights and freedoms of the employees, or on the compliance with a legal obligation, which does not apply to the use of personal devices.
Are not limited to what is necessary for the purposes of the monitoring, as they involve the collection and processing of excessive and irrelevant personal data, such as camera and microphone monitoring, screen captures, keystrokes, and facial recognition data, which go beyond the scope of the work performed by the employees, and intrude into their private or personal sphere.
Are not transparent to the employees, as they do not inform them of the monitoring and its precise scope, and do not give them the opportunity to object or opt out of the monitoring.
Involve the processing of special categories of personal data, such as biometric data or data revealing political opinions or trade union membership, which are not necessary or proportionate for the purposes of the monitoring, and which do not fall under any of the exceptions listed in the regulation.
Involve the transfer of personal data to a third country, such as China, which does not provide an adequate level of data protection, and which may pose additional risks for the rights and freedoms of the employees.
