Germany's Three-Week Trap: Even Illegal Firings Stand If Employees Miss Deadline

A string of recent rulings from Germany’s top labor courts has exposed a harsh reality for workers: procedural errors by employers can render a dismissal unlawful, but employees lose all protection unless they file a lawsuit within 21 days of receiving the termination notice.

The Federal Labor Court (BAG) delivered two judgments on April 1, 2026 (docket numbers 6 AZR 152/22 and 6 AZR 157/22) that set strict limits on mass redundancies. In the first case, an insolvency administrator fired 25 employees without ever submitting the mandatory mass-layoff notification to the employment agency. In the second, an airline filed the notification before completing the consultation process with the works council. The BAG ruled both dismissal sets invalid.

Just days earlier, on March 19, the BAG’s Second Senate (case 2 AS 22/23) had clarified a fundamental point: a missing or defective notification cannot be fixed retroactively. The statutory blocking period never starts, so the dismissals are void from the outset.

Yet the true sting for employees comes from a procedural deadline. Regardless of how egregious the employer’s mistake, a worker must bring a wrongful-dismissal claim within three weeks of receiving the notice. Miss that deadline, and the termination becomes legally binding — even if the employer broke the law.

Common Traps in Individual Dismissals

For operational reasons, the most frequent flaw is an improper social selection. Companies are allowed to group employees by age to preserve a balanced workforce, but any sloppiness in weighing tenure, age, support obligations, and disability status typically sinks the dismissal.

In conduct-related firings, home-office violations and irregularities in expense reports are emerging as high-risk areas. A June 15 ruling by the Solingen Labor Court (case 3 Ca 1629/25) illustrates the financial stakes: a plaintiff lost entitlement to a severance payment exceeding €415,000 after using the company’s internal purchasing system for private orders. The court deemed this a severe breach of duty that destroyed the basis of the termination agreement.

Government Plans to Reshape Dismissal Protection

While the courts are tightening enforcement of existing rules, the federal government unveiled a broad labor law package in early July that would fundamentally weaken protections for millions of workers. The centerpiece: raising the threshold for general dismissal protection from 10 to 50 employees. In future, firms with 50 or fewer staff could fire workers without having to prove social justification.

This change would hit employees in medical practices, law offices, and craft businesses hardest. Special protections for pregnant women, severely disabled workers, and works council members would remain untouched.

For high earners — those with annual income above €177,450, or roughly €15,000 per month — a separate simplified dissolution model is planned for January 1, 2027. The government is discussing automatic validity of a dismissal if the employer pays 0.5 monthly salaries per year of service. That would affect approximately 2.4 million full-time employees.

Other Reforms on the Table

The coalition also aims to extend fixed-term contracts without a specific reason: until December 31, 2030, these could run up to 48 months with up to six renewals. The requirement for a written contract form would be dropped.

Sick-pay rules are also set to change. Employees will need to present a doctor’s certificate from the first day of illness, ending the phone-based sick note that became common during the pandemic.

Standard Notice Periods Remain Unchanged

Despite these reforms, the basic notice periods under Section 622 of the German Civil Code stay intact: four weeks to the 15th or the end of a calendar month. After 20 years of service, the period extends to up to seven months. A two-week period applies during probation. Collective agreements may deviate, but cannot undercut the statutory minimums.

A late delivery of the notice does not make it invalid — it merely shifts the termination date to the next possible effective date.
