A formal warning letter causes uncertainty for many employees. Yet, first and foremost, it is one thing: a warning. The employer uses it to express that they consider a certain behavior to be a breach of contract and that consequences will follow in the event of a repeat offense—in the worst case, even termination.

Legally, a written warning serves three functions: it addresses a specific instance of misconduct, warns of further action, and serves as documentation. The so-called “principle of specificity” is crucial here: the allegation must be formulated in concrete and comprehensible terms—general accusations are not sufficient.

A common misconception is that three written warnings are always required before termination. This is not true—the circumstances of the individual case are always decisive. Often, a single relevant written warning may be sufficient to justify a subsequent termination for cause. In cases of particularly serious breaches of duty, a written warning may even be entirely unnecessary. Other myths also persist: A written warning does not necessarily have to be issued in writing, nor does it automatically disappear from the personnel file after a certain period of time. Likewise, there is no fixed deadline by which it must be issued—though its impact may diminish over time.

If you have received a written warning, the following applies: Stay calm and check whether the allegation is specifically worded and factually accurate. Depending on the situation, it may make sense to submit a counterstatement to the personnel file or to take legal action against the written warning. In any case, you should not make any hasty decisions—a well-considered approach is crucial.
