Germany's Top Labour Court Delivers Blow to Employers: Registered Mail No Longer Proves Termination Was Received

A landmark ruling from the Federal Labour Court (BAG) on May 7, 2026 (case 2 AZR 184/25) has fundamentally altered how companies must prove that dismissal letters actually reached employees. The decision eliminates the long-held principle of prima facie evidence for registered mail with delivery confirmation — known in German law as Einwurf-Einschreiben.

The court found that the current digital scanning procedure used by Deutsche Post creates an unreliable record. Delivery staff now scan the postal receipt before dropping the item into the recipient's mailbox. The scan, judges concluded, only documents the preparatory step — not whether the envelope was successfully delivered.

The case that triggered the change involved an employer unable to prove that an invitation to a company's return-to-work program (Betriebliches Eingliederungsmanagement, or BEM) had actually reached the employee. As a result, the subsequent termination was declared invalid. Legal experts are now advising employers to switch to personal handover with witnesses, service by courier, or delivery through a court bailiff.

Common Mistakes That Undermine Dismissals

Employers face additional pitfalls beyond the delivery hurdle. A mid-July 2026 legal analysis identified five recurring errors that make behavioural dismissals vulnerable in court.

Vague accusations without specific factual detail remain the most frequent mistake. Valid written warnings must also explicitly include a threat of dismissal if the behaviour repeats. Timing is equally critical: a warning should be issued no later than two to three months after the incident. For summary dismissals (fristlose Kündigung), companies must respect the two-week deadline set out in § 626 (2) of the German Civil Code.

For workers who lose their jobs through a lawful behavioural dismissal, the financial consequences are steep: a twelve-week waiting period for unemployment benefits (Arbeitslosengeld I) plus a reduction in the total benefit duration.

Proportionality Still Governs Even Serious Misconduct

Two regional labour court rulings illustrate that judges continue to weigh proportionality stringently.

The Bremen Labour Court (LAG Bremen) ruled on February 10, 2026 (case 1 SLa 75/25) that a summary dismissal for sexual harassment was disproportionate. A male employee in partial retirement had slapped a female intern on the buttocks. While the court classified the act as sexual harassment, it highlighted the man's 27-year unblemished record with the company and his immediate expression of remorse. Less severe measures — such as a formal warning or transfer — would have been sufficient.

By contrast, the Hamm Labour Court (LAG Hamm, case 13 Sa 1007/22) upheld the summary dismissal of a cleaning worker who had clocked in and then left to drink coffee without authorisation. Despite the employee's severe disability and long tenure, the court ruled that deliberate time theft made a preliminary warning unnecessary. The conscious falsification of time records outweighed any mitigating factors.

Formal Errors in Return-to-Work Procedures

Even illness-related terminations are not safe from procedural mistakes. The Cologne Labour Court (LAG Köln) ruled on October 23, 2025 (case 6 SLa 184/25) that a dismissal is invalid if the employer fails to clarify an employee's contradictory behaviour during the BEM process.

In that case, a worker had declined participation in BEM on an official form but simultaneously demanded the involvement of a works council member. The employer should have resolved this misunderstanding before issuing a notice of termination — not after.

Tough Market Conditions and Upcoming Legislative Changes

The tightening of legal requirements comes at a time when the German labour market is under pressure. The April 2026 Kündigungsreport (termination report) shows that 62% of dismissed employees accept the first severance offer without renegotiating. At the same time, 47% of terminated workers receive no compensation at all.

The ifo Employment Barometer stood at 92.3 points in June 2026. Surveys conducted by the German Economic Institute (IW) indicate that one in three businesses is planning to cut jobs.

A new legislative package agreed in July 2026 adds further complexity. It aims to standardise the requirement for a medical certificate of incapacity for work (Arbeitsunfähigkeitsbescheinigung, or AUB) from the first day of illness. The reform would also abolish the telephone sick note. The legislative process is expected to conclude by the end of 2026, though employers already have the right under current law to demand a medical certificate from day one.
