Introduction: ZealiD Service and Information Security Policy

ZealiD is a Qualified Trust Service Provider (QTSP) specializing in issuing eIDAS-qualified electronic signatures (QES) and identity verification services. It operates under stringent regulatory supervision, ensuring compliance with the eIDAS Regulation (EU No 910/2014), which mandates legally binding and cross-border-recognized trust services.


Information Security Policy


ZealiD follows strict security measures, as outlined in its Certificate Practice Statement (CPS). These measures include:

 

  • End-to-end encryption and cryptographic key management.
  • Multi-factor authentication (MFA) for secure user access.
  • Data minimization and access control, ensuring only authorized processing.
  • Audit trails and log retention for legal and security compliance.
  • ETSI 319 401, 319 411-1/2 compliance for operational and IT security best practices.

These practices ensure ZealiD meets the highest standards for personal data protection in digital identity and HR applications.

 

Qualified eSignatures in the HR Space

As per EU labor regulations, including the Directive (EU) 2019/1152 on Transparent and Predictable Working Conditions, HR processes increasingly require qualified electronic signatures (QES) for contracts, worker documentation, and dispute resolution. QES ensures:

 

  • Legal certainty equivalent to handwritten signatures.
  • Tamper-proof authentication, reducing fraud and document manipulation.
  • Cross-border recognition across all EU member states.
Traditional Wet-Ink Signing vs. Digital eSigning

Use Case: Traditional Paper-Based Employment Agreement Signing

 

In a traditional employment agreement process, the following steps occur:

  1. The employer prints multiple copies of the agreement.
  2. The worker is required to visit the HR office to sign the agreement.
  3. Each party signs the contract in ink, with potential witness signatures.
  4. Physical copies must be archived securely, often requiring extensive document storage and retrieval processes.
  5. If modifications are required, new versions must be printed, signed again, and re-archived.

Challenges with the Traditional Process:

 

  • Time-consuming: Requires physical presence and multiple document exchanges.
  • Security risks: Physical documents can be lost, forged, or tampered with.
  • Cost-intensive: Printing, storage, and couriering costs add unnecessary expenses.
  • Inefficient tracking: Paper contracts require manual verification for compliance audits.

Use Case: Digital Signing with ZealiD QES

 

  • The employer uploads the contract to a secure digital signing platform.
  • The worker receives a notification and opens the agreement via the ZealiD app.
  • Using qualified electronic signatures (QES), the worker signs the document remotely with full legal compliance.
  • A tamper-proof digital audit trail is generated, ensuring authentication and non-repudiation.
  • The signed contract is instantly stored in a secure digital repository, accessible anytime for compliance checks.

Benefits of Digital eSigning:

 

  • Time-efficient: Remote signing eliminates the need for in-person visits.
  • Increased security: Strong cryptographic protections prevent tampering or fraud.
  • Legally binding: Recognized under eIDAS Regulation across all EU member states.
  • Cost savings: No paper, printing, or couriering required.
  • Improved accessibility: Digital copies ensure easy retrieval for HR and employees.

Legal background: Establishing Workers' Digital Identification Rights

 

Several key legal cases and EU regulations have shaped digital identification and eSigning rights for workers:

 

1. European Court of Justice (ECJ) Case: Verein für Konsumenteninformation v Amazon (C-649/17)

  • The ruling emphasized the requirement for transparency in digital contracts, ensuring workers have clear consent mechanisms and non-repudiable proof of agreement.

2. EU Regulation (EU) 2019/1152 on Transparent and Predictable Working Conditions

  • This directive mandates that employment agreements must be accessible, secure, and transparent for workers, directly supporting the use of qualified eSignatures.

3. European Trade Union Confederation (ETUC) Position on Digitalization

  • ETUC has repeatedly emphasized the importance of digital trust services in ensuring worker protections and preventing employer exploitation in digital contract handling. A 2023 ETUC whitepaper advocated for "mandatory QES adoption in digital labor agreements to safeguard workers' rights against coercion and fraud."

4. Case Study: Spanish Supreme Court Ruling on Digital Employment Contracts (STS 367/2022)

  • The court ruled that digital employment contracts signed with qualified eSignatures are fully enforceable, setting a precedent for national labor courts to accept QES-based agreements as legally binding.

By adopting ZealiD’s QES, HR departments and trade unions ensure that workers have enforceable and tamper-proof employment rights, aligned with evolving EU legislation and labor protections.

 

The Role of Unions in Supporting HR Digital Transformation

Unions play a critical role in supporting HR digital transformation as it aligns with worker protection, accessibility, and efficiency in employment processes.

Key Benefits for Workers
  1. Stronger Data Protection – Unions ensure that digitalization respects GDPR rights, securing worker data against misuse.
  2. Transparency and Fairness – By supporting digital contract solutions like ZealiD QES, unions reinforce traceability and non-repudiation in employment agreements.
  3. Accessibility and Inclusion – Digital processes help eliminate paperwork inefficiencies, allowing remote signing and better compliance with labor rights.
  4. Prevention of Coercion – QES adoption ensures that workers do not face forced consent situations, as their authentication process is tamper-proof and independent of employer control.
Examples of Union-Led Digitalization Initiatives


The Nordic Unions Digital Agreement Framework, which promotes standardized digital contract solutions to improve workplace efficiency.
German Trade Union Confederation (DGB)'s advocacy for stronger worker eID protections, ensuring digital contracts uphold employment rights.
French CFDT’s Workplace Digital Transformation Initiative, which partners with tech providers to make HR services more accessible while ensuring strong data protection frameworks.

 

Conclusion

The adoption of ZealiD’s qualified electronic signature service within HR processes ensures legal certainty, worker protection, and GDPR compliance. By aligning with EU regulations and union expectations, ZealiD provides a trusted digital identity solution that enhances employment transparency and security.


Key takeaways include:

  • Digital transformation in HR benefits both employers and workers, ensuring efficiency and security.
  • Unions play a vital role in advocating digital tools that protect worker rights while improving accessibility.
  • ZealiD’s QES solution provides a secure, legally compliant, and transparent approach to employment agreements.
