Types of work contracts
Permanent labour contract (Vast contract)
A permanent contract is contract that has no end date. This form of contract can only be canceled if the employee resigns or if the employer discovers a compelling basis to do so.
Permanent contracts can only be terminated if the employee resigns (if the employees find a new job, for personal reasons, immigrating to a new country, etc.) or if the employer finds a justification to do so (which must comply with strict legal guidelines). Learn more about contract termination.
Other forms of contracts can also become permanent, even if they were not initially. For example, if you are offered three temporary contracts in a row, it is required by law that the fourth one must be a permanent contract
Temporary labour contract (Tijdelijk contract)
In the Netherlands, this is the most frequent form of labor contract. The temporary labour contract, also known as a fixed term contract, is only valid for a set period of time, generally six months or a year. Your employer is legally entitled to let you know if your contract is going to be extended at least one month before your contract end unless agreed otherwise. For example you can agree with your employer that this is just a temporary one time contract.
You can also terminate the contract from your end as an employee with an agreement from the employer. It can be because you do not enjoy the work or atmosphere in your company, or because you found a different job.
Zero-hour contract (Nul uren contract)
The zero-hour contract is a contract where the employee has no set working hours. This means that an employee might be asked to work 40 hours in one week and only 8 hours the next week for example. It is a flexible arrangement that is normally signed for a certain amount of time, but it might leave employees feeling less secure than a temporary or permanent contract. Generally speaking however, you will get less advantages compared to a normal temporary or permanent contract like paid leave and sick leave, unless stated differently in the contract.
Freelancer contract (DBA modelovereenkomst)
Freelancers are usually required to sign a specific type of contract defining their working relationship with the employer even if they are not directly an employee of a certain company. This helps all parties understand specific tasks to be carried, how many hours of work and payment in addition to which party is responsible for the employee’s welfare contribution.
