A non solicitation clause in a Netherlands employment contract is regarded as special form of a non-competition clause and thus subject to the rules of Article 7:653 DCC. Where a non-competition clause prohibits the employee from performing certain activities, a non solicitation clause usually prohibits the employee from engaging with certain parties. There are clauses that prohibit the employee from doing business with some named customers, but also clauses that prohibit to work for all customers and suppliers of the employer.
