Managing Employee Data Across EU and US Offices Under GDPR

The HR Data Challenge in Transatlantic Organizations

For companies with offices in both the EU and the United States, managing employee data is a constant balancing act. GDPR imposes strict rules on how employee personal data can be processed, stored, and transferred. US employment law takes a very different approach. HR departments caught between these two systems must find practical solutions that comply with both.

This guide addresses the real-world challenges that HR teams face and offers practical strategies for managing employee data across the Atlantic.

What Employee Data Is Covered?

HR departments process extensive personal data:

Standard Employment Data

• Names, addresses, contact details
• Date of birth, gender, nationality
• Employment contracts and amendments
• Job titles, departments, reporting lines
• Compensation and benefits details
• Bank account information for payroll

Sensitive Employment Data

• Health information (sick leave, disability accommodations, medical certificates)
• Trade union membership
• Religious beliefs (for accommodation requests)
• Racial or ethnic origin (for diversity monitoring)
• Criminal background check results
• Biometric data (fingerprints for access, facial recognition)

Performance and Development Data

• Performance reviews and ratings
• Training records
• Disciplinary records
• Promotion history
• Development plans

Data Category	GDPR Classification	Typical Legal Basis
Basic employment data	Personal data	Contract performance
Compensation and benefits	Personal data	Contract performance, legal obligation
Health data	Special category	Employment law, explicit consent
Diversity data	Special category	Substantial public interest (with safeguards)
Background checks	May be special category	Legal obligation, legitimate interest
Performance data	Personal data	Legitimate interest

GDPR Requirements for Employee Data

Lawful Basis

Contrary to common belief, employee consent is generally not the appropriate basis for most processing under GDPR. The power imbalance between employer and employee means consent is rarely "freely given." Instead, HR departments typically rely on:

• Contract performance -- processing necessary to fulfill the employment contract
• Legal obligation -- processing required by employment, tax, or social security law
• Legitimate interest -- processing necessary for the employer's legitimate interests, balanced against employee rights

Key GDPR Principles for HR

• Purpose limitation -- employee data collected for payroll cannot be used for marketing
• Data minimization -- collect only what is necessary for the employment purpose
• Storage limitation -- delete data when no longer needed for the purpose
• Accuracy -- keep employee records up to date
• Transparency -- inform employees about how their data is processed (privacy notice)

Employee Rights Under GDPR

Employees have the same GDPR rights as any data subject:

• Right to access their personal data
• Right to rectification of inaccurate data
• Right to erasure (limited by retention obligations)
• Right to data portability
• Right to object to processing based on legitimate interest
• Right not to be subject to purely automated decision-making

Cross-Border Transfer Challenges

The Core Issue

When a US-headquartered company has EU employees, employee data often needs to flow to the US for:

• Centralized HR systems (Workday, SAP SuccessFactors, BambooHR)
• Global payroll processing
• Group-wide reporting and analytics
• Headquarters management oversight
• Benefits administration

Each of these transfers must have a valid legal mechanism under GDPR.

Transfer Mechanisms

Mechanism	Suitability for HR Data	Considerations
EU-US Data Privacy Framework	Suitable if US entity is certified	Must verify certification status
Standard Contractual Clauses	Widely used for HR transfers	Requires Transfer Impact Assessment
Binding Corporate Rules	Best for large multinationals	Expensive and time-consuming to implement
Derogations (Art. 49)	Very limited applicability	Not suitable for systematic HR transfers

Transfer Impact Assessments

For any EU-to-US transfer, organizations should conduct a Transfer Impact Assessment:

• Assess whether US law provides adequate protection
• Evaluate the specific data types being transferred
• Determine whether supplementary measures are needed
• Document the assessment and keep it updated

Practical Strategies

Strategy 1: Localized Processing Where Possible

Minimize cross-border transfers by processing EU employee data in the EU:

• Use EU-hosted instances of HR platforms
• Process EU payroll within the EU
• Store EU employee documents in EU data centers
• Conduct EU performance management within the EU

Strategy 2: Data Minimization for Transfers

When cross-border transfer is necessary, minimize what is transferred:

• Transfer aggregated rather than individual data for reporting
• Pseudonymize data before transfer where feasible
• Limit US-based access to what is truly necessary
• Avoid transferring special category data unless absolutely required

Strategy 3: Technical Safeguards

Implement technical measures to protect transferred data:

• Encrypt data in transit and at rest
• Use access controls that limit who in the US can access EU employee data
• Implement audit logging for all cross-border data access
• Consider encryption with EU-held keys for the most sensitive data

Strategy 4: Clear Internal Policies

Develop policies that HR teams can actually follow:

• Define which data stays in the EU and which can be transferred
• Specify approved platforms for each type of HR data
• Establish procedures for handling employee rights requests
• Create retention schedules that account for both EU and US requirements

Strategy 5: Vendor Configuration

Configure HR technology platforms for compliance:

• Enable data residency features where available
• Restrict sub-processor locations
• Configure retention and deletion in line with policies
• Enable audit logging
• Review vendor DPAs and ensure they address cross-border transfers

Common Pitfalls

Pitfall 1: Relying on Employee Consent

Many companies ask EU employees to consent to data transfers. This is problematic because:

• Consent must be freely given -- employees may feel pressured
• Consent can be withdrawn at any time
• If consent is the only basis, withdrawal creates immediate compliance issues
• Regulators have repeatedly warned against relying on consent for employment data

Pitfall 2: Ignoring Works Councils

In many EU countries (Germany, France, Netherlands), works councils have co-determination rights on employee data processing:

• Introducing new HR technology requires works council consultation
• Data processing agreements may need works council approval
• Cross-border transfers may require works council notification
• Monitoring tools (even productivity analytics) require agreement

Pitfall 3: One-Size-Fits-All Privacy Notices

EU employees need specific, detailed privacy notices that differ from those given to US employees:

• Legal basis for each processing activity
• Specific retention periods
• Cross-border transfer details and safeguards
• Employee rights and how to exercise them
• Contact details for the Data Protection Officer

Pitfall 4: Retaining Data Too Long

Different jurisdictions have different retention requirements:

Data Type	Germany	France	UK	US
Payroll records	10 years	5 years	6 years	4-7 years (varies)
Employment contracts	3 years after termination	5 years	6 years	Varies by state
Health records	Varies	5 years	40 years (occupational health)	OSHA: 30 years
Application data (rejected)	6 months	2 years	6 months recommended	Varies

Applying the longest retention period globally creates GDPR violations for EU data. Implement jurisdiction-specific retention schedules.

Technology Solutions

HR Platform Configuration

Most modern HR platforms offer data residency options:

• Workday -- regional data centers with configurable hosting
• SAP SuccessFactors -- EU-hosted instances available
• BambooHR -- US-hosted (consider supplementary measures for EU data)

Document Management

HR documents (contracts, performance reviews, medical certificates) need secure, jurisdiction-aware storage. GlobalDataShield offers document-level data residency that allows HR departments to store each employee's documents in their home jurisdiction while maintaining authorized access for HR teams across offices.

Key Technology Requirements

• Data residency controls at the document or record level
• Encryption at rest and in transit
• Role-based access controls
• Comprehensive audit trails
• Automated retention and deletion
• Employee self-service access to their own data

Conclusion

Managing employee data across EU and US offices requires deliberate planning, the right technology infrastructure, and ongoing attention to regulatory changes. HR departments that build compliance into their processes -- rather than treating it as an afterthought -- will avoid regulatory issues and build employee trust.

Start by mapping your employee data flows, identifying cross-border transfers, and ensuring each transfer has a valid legal mechanism and appropriate safeguards. Then implement the technology and policies to enforce those requirements consistently.
