Definition
A written warning is a formal notice issued by the employer. It specifies a particular instance of misconduct, declares it to be unacceptable and threatens dismissal should it be repeated. Dismissal on grounds of conduct is generally invalid without a prior written warning. The employee may object – their counterstatement will then be included in the personnel file. Unjustified or outdated warnings must be removed from the personnel file upon request.

Classification under employment law
A written warning is the ‘yellow card’ of employment law. The employer reprimands the employee for specific misconduct and threatens dismissal in the event of a repeat offence. Without a prior written warning, dismissal on grounds of conduct is generally invalid.
Distinction from related terms
Admonition: An admonition is a non-binding reprimand with no legal consequences. A written warning, on the other hand, serves as a clear warning and may form the basis for further action under employment law.
Warning: The term ‘warning’ is often used colloquially as a synonym, but is not clearly defined in legal terms. A formal warning, on the other hand, is a well-established term in employment law with a clear function.
Practical tip
Never sign a warning letter with the words “I agree”. Check the facts carefully – you can refute an incorrect warning letter by submitting a counterstatement or request that it be removed from your personnel file. Although there are no specific deadlines, you should act promptly.
