German Court Orders VW to Pay Full Anniversary Bonuses, Rejects Retroactive Whistleblower Protection

Two rulings from the Lower Saxony State Labour Court on 29 May 2026 sent contrasting signals for German employees. In one case, the court sided with workers, ordering Volkswagen AG to pay full anniversary bonuses to two staff members whose milestone work anniversaries fell on 1 January 2025. In the other, it dismissed claims from whistleblowers seeking compensation for alleged retaliation.

Anniversary bonuses must be paid under old rules

The Volkswagen case turned on timing. A collective agreement signed on 21 January 2025 sought to reduce the bonus amounts retroactively. The court ruled that this could not apply because the employees’ service anniversaries had already occurred before the new deal was struck.

Under the earlier terms, each employee is entitled to bonuses worth 1.45 and 2.9 monthly salaries respectively. The judgement is not final and can be appealed.

Whistleblower claims fail on two fronts

The separate whistleblower case involved employees backed by the organisation OMK. They argued that internal reports they had made led to disadvantages at work and demanded damages under Germany’s Whistleblower Protection Act (Hinweisgeberschutzgesetz, HinSchG).

The court rejected their claims on two independent grounds. First, the key internal communications took place before the HinSchG came into force. German law does not apply the statute’s protections retroactively to events already concluded. Second, even if the timeline had been different, the plaintiffs failed to present sufficient concrete evidence that specific reprisals followed their reports. That evidentiary gap removed a core requirement for legal protection.

The case can now go to the Federal Labour Court (Bundesarbeitsgericht, BAG), which was allowed to hear the appeal. The BAG will have the chance to clarify fundamental questions about how the HinSchG applies: who bears the burden of proof when a worker claims retaliation, and what standard of evidence is required.

Similar hurdles appeared in other recent rulings

The High Labour Court of Hamm reached a comparable conclusion in February 2026. There, an employer sought damages after a staff member deleted roughly 19,000 emails. That claim also failed because the alleged harm could not be proven with sufficient specificity.

Taken together, the decisions underline how crucial precise cut-off dates and clear documentation are in German labour disputes — whether the issue is protecting whistleblowers or enforcing collectively bargained bonus entitlements.
