We speak of an employment contract if one party, (the employee), commits himself to perform work in the service of the other party, (the employer), in exchange for wages during a certain period of time. Any agreement that meets this definition is an employment contract. It does not matter what name the parties have given to the agreement. If the agreement between the parties contains the elements of personal labour, wages and a relationship of authority, it is an employment contract. What labour and wage means is often clear. This does not apply to the element “relationship of authority”. In short, this means that the employer may instruct the employee what work to do, when to do it and how to do it. It also means that, for example, the employee is bound by the company regulations, such as those regarding sick leave and taking holidays.
If there is an employment contract, it has important consequences. An employment contract is subject to labour law. Labour law has many (mainly mandatory) provisions to protect the employee. Think, for example, of the obligation to continue to pay wages in the event of incapacity for work, the accrual of holidays and the (limited) possibilities for dismissal. In addition, in the event of an employment contract, an employer is obliged to withhold wage tax and social security contributions. Also, in general, the employee cannot bluntly be dismissed. The employer is bound by dismissal law. Here you can read more about dismissal law.
Service agreement
It can be difficult to distinguish an employment contract from a service agreement, on the basis of which, for example, a self-employed person works. After all, both agreements imply that one party works for the other party against payment (e.g. an hourly rate). In a service agreement, however, there is no element of “authority”. Here you can read more about the service agreement of a self-employed person.
Formation of an employment contract
An employment contract is established by offer and acceptance. Although it is not a requirement for the formation of an employment contract, it is wise to write down the agreed terms of employment in advance so that there can be no ambiguity about this afterwards. The employment contract may also include whether company regulations or a collective labour agreement apply.
