Collective Redundancies: When a Failure to Notify the Employment Agency Brings Down Your Dismissal

In restructurings and insolvencies, employers often make redundancies on a large scale — but they don't always notify the Employment Agency correctly. A recent Federal Labour Court ruling shows when this renders your dismissal invalid.

Your employer is cutting jobs, and doing so in large numbers — restructuring, insolvency, a “group reorganisation”. You have received notice of dismissal. Word is going round among your colleagues: the employer supposedly never notified the redundancies to the Employment Agency, or did so incorrectly. Is that just bureaucratic box-ticking — or can it actually bring down your dismissal?

In brief

If your employer fails altogether to notify a collective redundancy to the Employment Agency, your dismissal is invalid — with no exceptions. If, by contrast, a notification was submitted but simply contains an error, the dismissal remains valid, provided the Agency can still do its job despite the error. This distinction reflects the case law of the Federal Labour Court. Whatever the position, the decisive factor is the deadline: you must bring your claim within three weeks of receiving the dismissal. Otherwise you lose the ability to raise this argument at all.

How I can help you

• Checking whether a notification to the Employment Agency was in fact required and whether one was submitted
• Reviewing and analysing the collective redundancy notification and the consultation procedure with the works council
• Protecting the deadline: filing the unfair dismissal claim within the three-week window
• Representing you before the Labour Court and challenging every ground of invalidity — not just the social justification

When a duty to notify actually arises

The duty to notify under § 17 KSchG does not apply to every wave of dismissals. It only bites once certain thresholds are reached, which depend on the size of the establishment. These figures must be met within 30 calendar days: in establishments with 20 to 60 employees, more than 5 dismissals are enough. In establishments with 60 to 500 employees, the threshold is 10% of the workforce or more than 25 dismissals. In establishments with 500 or more employees, it is at least 30 dismissals. Where a threshold is reached, the employer must do two things. It must consult the works council (§ 17(2) KSchG) and give the Employment Agency written notification of the collective redundancy (§ 17(1) and (3) KSchG). These two duties are treated as legally separate and carry different consequences when breached. In practice, that is exactly what many people run together.

The mechanism: why a missing notification renders the dismissal invalid

The legal lever lies in § 18(1) KSchG. Dismissals subject to the notification requirement do not take effect before the expiry of one month after the notification is received by the Employment Agency, unless the Agency consents. This blocking period serves a purpose: it gives the Employment Agency time to prepare for placing the affected employees and, where appropriate, to set measures in motion.

It follows that if no notification is received that actually enables the Agency to act, the blocking period cannot even begin to run. And if the blocking period never begins, it can never expire — which means the dismissal cannot take effect. Where a notification is entirely absent, the dismissal is therefore invalid. This is not a peripheral point but the very core of collective redundancy protection. It reflects the protective purpose of the Collective Redundancies Directive 98/59/EC. If the employer does not notify the planned redundancies in accordance with its requirements, that defeats precisely this objective.

The exception: where the notification is merely defective

The position is different where the notification is defective. The employer does submit the notification, but its content contains an error — for example, a slightly inaccurate number of affected employees. Here the Federal Labour Court has made clear that such errors do not automatically render the dismissal invalid. What matters is whether the Employment Agency could still perform its task despite the error. It must be able to act on the basis of the notification and prepare for placing the affected employees. On that basis, a minor numerical discrepancy is harmless if it does not impair the authority’s ability to function.

This distinction is decisive for your litigation strategy: not every error in the notification is a direct hit. Anyone who asserts, in blanket terms, that “the notification was defective, therefore the dismissal is invalid” is mistaken. What counts is whether the error actually impaired the notification’s effectiveness — that is, whether the Agency could still carry out its task. A missing notification is thus something fundamentally different from a defective one.

The second lever: the consultation procedure with the works council

The consultation procedure under § 17(2) KSchG is examined separately from the notification to the Employment Agency. The employer must inform the works council in good time and in writing — about the reasons for the planned redundancies, their number, the occupational groups affected, the period involved and the intended selection criteria. The aim is to discuss together ways of avoiding or reducing the redundancies and mitigating their consequences. If the employer breaches this duty to consult, that can render the dismissal void under § 134 BGB. This line of attack is independent of the duty to notify. Examine it separately: an employer may have properly informed the Agency yet still failed to carry out the consultation procedure with the works council — or vice versa.

Why the three-week deadline overrides everything

Here lies the real difficulty for you as an employee: from the outside, you generally cannot see what your employer notified to the Employment Agency, or whether it carried out the consultation procedure properly. That information sits with the employer. It typically only comes to light during the unfair dismissal proceedings, when the court requires the notification and the consultation documents to be produced.

Under § 4 KSchG, you must file a claim with the Labour Court within three weeks of receiving the written dismissal. Only in this way can you argue at all that the dismissal is legally invalid — whatever the ground. If you let this deadline pass, the dismissal is deemed valid from the outset once the three weeks are up. That holds true even if there was in fact a serious defect in the notification. You then lose not only the challenge to the social justification, but also the potentially far more powerful challenge based on a missing or defective collective redundancy notification. If you bring your claim in time, you preserve the ability to have these questions clarified later in the proceedings. That is so even if, at the point of filing, you do not yet know whether or how the employer notified the redundancies.

A typical case from practice

A company with around 200 employees, in the course of a restructuring, dismisses 40 employees within a few weeks. One of the affected employees receives their dismissal. Through the works council, they learn that there were said to be irregularities in the collective redundancy notification. At that stage, they do not know whether the employer actually notified the redundancies, whether the figures were correct, or whether it properly consulted the works council. They file an unfair dismissal claim in time and, as a precaution, challenge both the lack of social justification and possible breaches of the duty to notify and to consult. During the proceedings the court requires the notification to be produced. It then emerges that the employer had in fact submitted no notification at all. The dismissal is invalid.

Common mistakes

Many employees hold off filing their claim until they have “proof” of a notification error. In doing so, they miss the three-week deadline. Yet that proof, as a rule, only becomes available once the proceedings are under way. Just as common: employees base the unfair dismissal claim solely on the lack of social justification, without also raising, as a precaution, doubts about the proper collective redundancy notification and the consultation procedure. That can shut off this line of attack later. Some employees also confuse “the notification was defective” with “the notification is missing altogether” — two legally distinct situations with different prospects of success.

Your next step

If your employer has dismissed you as part of a larger wave of redundancies, one thing above all matters now: the deadline. Whether the notification and consultation procedure were handled properly can often only be established in the proceedings — but that opportunity exists only if you have filed your claim in time. How much time you have left, and what the path to an unfair dismissal claim looks like in concrete terms, is something you should clarify now. For more general information, see also Employment Law.

Frequently asked questions

As an employee, do I have to prove that no notification was submitted?

No — at least not off your own bat. Whether, and what, the employer notified is something only the employer knows. In the unfair dismissal proceedings, you can prompt the court to request the relevant documents or to order the employer to produce them.

What happens if I miss the three-week deadline?

The dismissal is then deemed valid from the outset — regardless of whether there was in fact an error in the collective redundancy notification. The deadline under § 4 KSchG is a mandatory precondition for being able to challenge the legal invalidity of a dismissal in court at all.

Does the duty to notify also apply in an insolvency?

Yes. The thresholds under § 17 KSchG apply in principle irrespective of whether the redundancies take place as part of an insolvency or some other restructuring. The insolvency administrator, too, must observe the duty to notify where the redundancies reach the relevant thresholds.

Is a small numerical error in the notification enough to bring down the dismissal?

Not automatically. What matters is whether the error prevented the Employment Agency from performing its task. A minor discrepancy does not render the dismissal invalid under the current case law of the Federal Labour Court, provided it does not impair the authority’s ability to function.

Does this affect smaller businesses too?

Only once certain thresholds are reached. In establishments with 20 to 60 employees, more than 5 dismissals within 30 days are already enough to trigger the duty to notify. So this genuinely affects small and medium-sized businesses too, not just large corporations.
