Non-compete clauses, customer protection agreements and post-contractual confidentiality obligations govern the relationship between employer and employee. They follow the rules of employment law, including its requirements on validity, scope and duration. A breach of such a clause does not automatically create a fair competition claim against the new employer.
On the other hand, a competitor that deliberately induces a bound employee to breach a valid clause or that knowingly exploits an existing tie may enter unfair territory. The prerequisites include a valid employment law obligation, awareness on the competitor side and sufficiently individualised interference. Mere employment of the person is not enough.
For the file, the non-compete clause, customer protection agreement and confidentiality duty should be documented with wording, date and signature. Communication with the competitor is preserved separately. Anyone weighing claims should consider fair competition and employment law paths in parallel, without merging them.
