Warning Letter (Abmahnung) in German Employment Law

Function and Legal Effect

An Abmahnung performs several related functions. It documents and identifies a contractual breach, requires the employee to comply with their obligations in future and warns that a comparable repetition may jeopardise the employment relationship. The employee must be able to understand what conduct is criticised, which contractual obligation has been breached, what compliant conduct is expected in future and that a comparable repetition may lead to dismissal.

A warning is primarily appropriate for controllable conduct. Where the issue results from incapacity, illness or another circumstance the employee cannot reasonably change, a conduct-based warning may be legally inappropriate. In those cases, the issue should be assessed as a person-related matter.

An Abmahnung may also be distinguished from an Ermahnung — a less severe corrective measure that may criticise conduct and request future compliance but does not contain the clear warning that repetition may jeopardise the employment relationship. An Ermahnung therefore does not normally perform the same dismissal-related warning function as an Abmahnung.

German law does not impose a general written-form requirement for an Abmahnung. An oral warning may therefore be legally effective, but it creates substantial evidentiary difficulties. Written warnings are standard because they document the allegations, the required future conduct and the consequences threatened for repetition. A written Abmahnung is commonly placed in the personnel file, although placement in the file is not a condition of its legal effectiveness.

For Employers — Drafting a Legally Effective Warning

A legally effective Abmahnung must address three elements precisely.

First, it must identify the conduct complained of with sufficient precision. The warning must identify the alleged conduct as precisely as the circumstances allow — ordinarily including the relevant incident, date or period, place and behaviour. General allegations concerning attitude, reliability or performance are insufficient. Where performance is criticised, the employer should identify the specific duty, the expected performance standard and the respects in which the employee culpably failed to meet it. A general allegation of poor performance is not sufficient.

Second, it must characterise the conduct as a contractual breach. The employer must also verify that the conduct actually breached an employment obligation. A warning based on an incorrect interpretation of the contract, an invalid instruction or conduct the employee was legally entitled to engage in may be subject to removal.

Third, it must warn of the employment-law consequences. The warning must make clear that a comparable future breach may jeopardise the continued employment relationship. It is not necessary in every case to threaten a specific form of dismissal, but a vague reference to unspecified consequences may be insufficient.

There is no fixed statutory deadline for issuing an Abmahnung. Prompt action is nevertheless advisable because a substantial unexplained delay may weaken the practical warning effect and, in exceptional circumstances, contribute to an argument that the employer no longer intended to pursue the matter. Delay alone, however, does not automatically invalidate a warning; its effect depends on the circumstances.

German law does not generally require the employee to be heard before an Abmahnung is issued. An applicable collective agreement, works agreement or public-sector provision may, however, impose additional procedural requirements. Obtaining the employee’s explanation before issuing the warning may also help avoid factual or legal errors. An acknowledgement of receipt should be distinguished from acceptance of the allegations: the employee may confirm receipt without agreeing that the warning is justified.

We draft warning letters for employers and advise on whether the conduct in question satisfies the threshold for a formal warning, and whether the matter would support a conduct-related dismissal on repetition. Further detail is on our employment law for employers page.

For Employees — Response Options

An employee who receives an Abmahnung has several options.

Counter-statement (Gegendarstellung): Under § 83(2) BetrVG, the employee may request that their statement concerning the contents of the personnel file be added to the file. A counter-statement does not by itself invalidate or remove the Abmahnung; its purpose is to document the employee’s factual and legal response. A counter-statement should be concise, factual and strategically considered. An unnecessarily emotional response, avoidable admissions or an inaccurate alternative account may weaken the employee’s position.

Request for removal from the personnel file: An employee may seek removal where the warning is insufficiently specific, contains incorrect factual allegations, is based on an incorrect legal assessment, is disproportionate, or where the employer no longer has a legitimate interest in retaining an otherwise justified warning. Removal may be sought by agreement or through court proceedings. The employer must still prove the relevant facts in any later dismissal proceedings; the existence of a warning in the personnel file does not by itself establish that the allegation was correct.

No immediate formal action: In some cases, the appropriate response is neither a counter-statement nor a formal removal demand, but to demonstrate compliant conduct going forward. The appropriate response depends on the specific circumstances and the employee’s strategic position.

We advise employees on the appropriate response and, where warranted, pursue removal of the warning from the personnel file. Further detail is on our employment law for employees page.

Multiple Warnings

Several valid warnings concerning comparable breaches may strengthen the employer’s position by supporting a negative prognosis. Repeated warnings can, however, also weaken the warning effect if the employer continually threatens dismissal but takes no further action; the employee must still be able to take the threatened consequence seriously.

Different breaches may be addressed in separate warnings. For a later dismissal, however, the employer may generally rely only on warnings whose warning function extends to the type of breach forming the basis of the dismissal. The later breach need not be factually identical, but it must be sufficiently similar in the nature of the contractual obligation violated for the earlier warning to remain relevant.

An expressly withdrawn warning will generally no longer provide the warning function required for a later dismissal. Where a warning has merely been removed from the personnel file, the consequences depend on why it was removed and what the parties agreed. The underlying incident may remain relevant in some contexts unless the employer has expressly abandoned the allegation.

Connection to Conduct-Related Dismissal

A relevant warning is normally required before an ordinary conduct-related dismissal under the KSchG where future compliance can reasonably be expected. Under the principle of proportionality, a warning may also be necessary before an extraordinary dismissal unless it would clearly be ineffective or the breach is so serious that prior acceptance could not reasonably have been expected.

A warning may be unnecessary where future compliance cannot reasonably be expected or where the breach is so serious that the employee could not have assumed the employer would tolerate it even once. Depending on the seriousness of the breach and the overall circumstances, an ordinary or extraordinary dismissal may then be considered. The statutory requirements and the proportionality assessment remain necessary in each case.

A comparable breach after a valid warning may support a conduct-related dismissal without a further warning. This is not automatic: the employer must still assess the similarity and seriousness of the new breach, the continuing warning effect, proportionality and the circumstances of the employment relationship. Further detail is on our termination protection page.

How Long Does an Abmahnung Stay in the Personnel File

German law does not impose a fixed period after which a warning must automatically be removed from the personnel file. There is no automatic right to removal merely because a certain period has passed or the employee has not repeated the conduct. Even where the warning has lost its immediate warning effect, the employer may retain a legitimate documentation interest. Removal of an originally justified warning generally requires that it has become legally irrelevant to the employment relationship in every respect.

Whether a legitimate retention interest remains depends on the seriousness of the original breach, the employee’s subsequent conduct, the employee’s position, the possible relevance to future personnel decisions and the overall duration of the employment relationship. After the employment relationship has ended, removal claims are subject to a different assessment; a continuing claim may require a specific risk that the retained warning or inaccurate information could still cause the former employee a disadvantage.
