GDPR and Employee Data Privacy

Employee Information Protection Under the GDPR

The General Data Protection Regulation (GDPR) establishes a strict framework for handling personal data, and this framework applies fully to the employer-employee relationship. As a data controller, your organization is responsible for the lawful, fair, and transparent processing of all employee information. This requires a proactive approach to governance, security, and communication.

Defining Employee Personal Data

Under the GDPR, employee personal data is any information that can identify an individual. This definition is broad and encompasses far more than just contact details. For HR teams, it is critical to understand the full scope.

• Core Identifiers: This includes name, home address, personal email, phone number, date of birth, national ID or social security number, and employee ID numbers.
• Employment and HR Records: All documentation related to the employment lifecycle falls under this category. Examples are application forms, CVs, interview notes, personnel files, performance reviews, disciplinary records, time and attendance logs, and training history.
• Payroll and Benefits Information: Salary details, bank account information, tax codes, pension contributions, and benefits enrollment data are all considered personal data.
• Special-Category Data: This is sensitive information that receives heightened protection. It includes health and medical data (including sick notes), disability information, racial or ethnic origin, religious or philosophical beliefs, trade-union membership, biometric data used for identification, and sexual orientation.

Processing special-category data is generally prohibited unless a specific GDPR exemption applies, such as obligations under employment law, explicit consent for a specific purpose, or protecting the vital interests of the employee.

Establishing a Legal Basis for Processing

You must identify and document at least one lawful basis for every instance of processing employee data. Relying on the wrong basis creates significant compliance risk.

Common lawful bases in an HR context include:

1. Performance of a Contract: This covers processing necessary to fulfill the employment contract, such as paying salary, providing agreed benefits, and managing contractual duties.
2. Compliance with a Legal Obligation: Use this for activities mandated by law, including tax reporting, social security deductions, health and safety record-keeping, and maintaining records required by employment statutes.
3. Legitimate Interests: This can apply for purposes like workforce management, IT security, fraud prevention, or internal reporting. However, you must conduct a balancing test to ensure your interests are not overridden by the employee’s rights and freedoms.
4. Consent: For consent to be valid, it must be freely given, specific, informed, and unambiguous, with a genuine ability to withdraw. Due to the inherent power imbalance in employment, regulatory guidance states that employee consent is rarely a reliable legal basis for routine HR processing. Prefer contract, legal obligation, or legitimate interests where possible.

Remember, for special-category data, you need both a standard lawful basis (from Article 6) and a separate condition for processing sensitive data (from Article 9), such as carrying out obligations under employment law.

Adhering to Core Data Protection Principles

All processing of employee data must align with the GDPR's six foundational principles. Treat these as operational mandates for your HR department.

• Lawfulness, Fairness, and Transparency: Process data only on a valid basis, do so fairly, and communicate your practices clearly.
• Purpose Limitation: Collect data for specified, explicit, and legitimate purposes. Do not later process it in a manner incompatible with those original purposes without a new legal basis and notice.
• Data Minimisation: Collect only the data that is necessary for your stated purpose. Regularly audit HR forms and processes to eliminate unnecessary data fields.
• Accuracy: Keep personal data accurate and up to date. Implement procedures to correct or delete inaccurate information promptly.
• Storage Limitation: Retain employee data only for as long as necessary for the purpose. You must define and enforce clear HR data retention schedules that consider both operational needs and legal archiving requirements.
• Integrity and Confidentiality: Ensure appropriate security of the data through technical measures (like encryption and access controls) and organizational measures (like policies and training).

The principle of accountability requires you to be able to demonstrate your compliance with all the above.

Providing Clear Employee Privacy Notices

Transparency is a legal requirement. When you collect employee data, you must provide clear privacy information under Articles 13 and 14 of the GDPR. Your employee privacy notice is the primary tool for this.

A comprehensive HR privacy notice should include:

• The identity and contact details of the employer (the data controller) and the Data Protection Officer, if one is appointed.
• The purposes for processing and the corresponding lawful bases, specifying both the Article 6 basis and any Article 9 condition for special-category data.
• The categories of personal data collected and who it will be shared with (e.g., payroll providers, benefits administrators, government agencies).
• Details of any international transfers of data outside the European Economic Area and the safeguards in place.
• The retention periods for different categories of data, or the criteria used to determine them.
• A clear summary of the employee rights under the GDPR and instructions on how to exercise them.
• The right to lodge a complaint with a supervisory authority.

Provide this notice at the recruitment or onboarding stage and update it whenever your processing activities change significantly.

Managing Employee Data Subject Rights

Employees retain their full suite of GDPR rights, though some may be subject to limitations or exemptions in the employment context. You must have robust procedures to handle requests.

Key rights include:

• Right of Access: Employees can request a copy of their personal data and related information. You must typically respond within one month.
• Right to Rectification: Employees can request correction of inaccurate or incomplete data.
• Right to Erasure ("Right to Be Forgotten"): Employees can request deletion in specific situations, such as when the data is no longer necessary. This right may be restricted by legal obligations to retain records.
• Right to Restriction of Processing: Employees can request you limit the processing of their data under certain conditions, such as while the accuracy of the data is being contested.
• Right to Object: Employees can object to processing based on legitimate interests or for direct marketing purposes.
• Right to Data Portability: Where processing is based on contract or consent and carried out by automated means, employees can request their data in a structured, commonly used, machine-readable format.

Establish a formal process to recognize, log, assess, and respond to these requests within the statutory timeframes.

Implementing Security and Breach Response

You must implement appropriate technical and organizational security measures to protect employee data, proportionate to the risk.

Typical HR security controls include:

• Role-based access controls, ensuring employees can only access data necessary for their role (principle of least privilege).
• Encryption of sensitive data both at rest (in databases) and in transit (over networks).
• Redaction of unnecessary personal identifiers in shared internal documents.
• Strong authentication methods, audit logging, and regular security assessments of HR systems.
• Conducting due diligence on vendors and having signed data processing agreements with all HR service providers (e.g., payroll, benefits platforms).

Personal Data Breach Response: If a security incident leads to the accidental or unlawful destruction, loss, alteration, or disclosure of employee personal data, you must act swiftly. If the breach poses a risk to individuals' rights and freedoms, you are obligated to notify your supervisory authority within 72 hours of becoming aware of it. If the risk is high, you must also inform the affected employees without undue delay.

Conducting DPIAs and Maintaining Records

For higher-risk processing activities, the GDPR mandates specific documentation and assessment.

• Data Protection Impact Assessment (DPIA): You must conduct a DPIA before processing that is "likely to result in a high risk." In HR, this includes large-scale systematic monitoring of employees (e.g., extensive email or internet monitoring), automated profiling that significantly affects individuals, or large-scale processing of special-category data (like health information across your entire workforce).
• Data Protection Officer (DPO): You must appoint a DPO if your core activities involve large-scale, regular, and systematic monitoring of individuals, or large-scale processing of special-category data. A large workforce often triggers this requirement. The DPO advises on compliance, monitors your activities, and acts as a contact point.
• Records of Processing Activities (RoPA): Most organizations are required to maintain an internal record of all processing activities. Your HR RoPA should detail the purposes of processing, data categories, data recipients, international transfers, and retention schedules for all employee data flows.

Considering National Employment Rules

GDPR Article 88 allows EU member states to introduce more specific rules concerning the processing of employee data. These national laws may provide further detail or conditions for processing in contexts like recruitment, performance management, equality monitoring, and whistleblowing.

National rules must include suitable and specific measures to safeguard the employee’s human dignity, legitimate interests, and fundamental rights.

In practice, this means your HR compliance must be a two-layer check: first against the GDPR, and second against the employment and data privacy laws of each country where you have employees.
