Türkiye's Personal Data Protection Board (KVKK) has published a principle decision setting out the rules employers must follow when monitoring corporate email accounts and other communication channels provided to employees for work. Decision No. 2026/2035, dated September 16, was announced to the public on October 8.
The Board stressed that ownership of an email account or communication system does not give an employer unlimited monitoring authority. Reviewing message content, traffic data or system logs all constitutes personal-data processing. Monitoring must therefore comply with the processing conditions, general principles, disclosure duties and data-security requirements under Law No. 6698.
The decision follows complaints and reports alleging that workplace communication channels were monitored, message content accessed and collected information used in disciplinary or termination proceedings. The Board said some employees had not been given sufficiently clear, specific information about those monitoring activities.
Employees must receive specific advance notice
Employees must be informed in advance about the legal basis, purpose, scope and method of monitoring. The notice should explain whether the employer will examine only traffic or log data, when message content may be accessed, who may receive the resulting data and how long the information will be retained.
A generic statement saying that a corporate email account may be monitored is not automatically sufficient. KVKK distinguishes advance notice from the formal disclosure obligation under Article 10 of the law and says both requirements must be assessed in light of the specific circumstances.
Content review should be a last step
The decision requires a graduated approach. If an employer can achieve a legitimate purpose by reviewing traffic data or using another less intrusive method, it should not move directly to message content. Content inspection should arise only in exceptional cases involving a concrete suspicion or a legitimate purpose connected to a specific incident, after less intrusive measures prove inadequate.
Undefined, general and continuous examination of communications should be avoided. The Board says secret monitoring without advance notice and tools that indiscriminately record every employee action will be considered unlawful. Monitoring must be tied to a specific, explicit and legitimate purpose and remain relevant, limited and proportionate.
Technical access is not legal permission
An employer's technical ability to access a device, session, network or corporate system does not mean it may freely enter an employee's personal email, private messaging application or social-media inbox. The decision expressly separates technical capability from legal authority.
Employers may establish rules governing business and private use of workplace communication tools, but those rules must be clear, understandable and accessible to employees. Even when private use is prohibited, monitoring remains limited by proportionality. Where business and personal use cannot be clearly separated, the permitted scope should be assessed more narrowly.
Data security and the end of employment
Access to information collected through monitoring should be restricted to a limited number of authorized personnel. Access logs must be maintained and confidentiality obligations secured. Data may be retained only for the period required by the stated purpose. Ending the employment relationship does not automatically justify indefinite access to or processing of a former employee's mailbox data.
KVKK said suspected violations will be examined according to the circumstances and that administrative action may be taken against data controllers under Article 18 of the law. The decision does not prohibit every form of workplace monitoring. Instead, it requires a proportionate balance between an employer's legitimate management needs and employees' rights to privacy, confidential communications and protection of personal data.
