What is a purpose-defined CDD (or Mission CDD)?

Verified 24 June 2021 - Directorate for Legal and Administrative Information (Prime Minister)

A fixed-term fixed-term contract (or assignment contract) is a form of fixed-term contract which has the particular feature of terminating when the assignment for which it was concluded ends. This contract is reserved for the recruitment of engineers and executives. It has a minimum duration and a maximum duration. The contract may, however, be terminated in advance under certain conditions.

A fixed-purpose contract (or assignment contract) is an employment contract that ends when the object for which it was concluded is achieved.

The purpose-defined CDD is reserved for the recruitment of engineers and managers.

It must be provided for by an extended branch agreement or by a company agreement.

The purpose-defined CSD is reserved for the private sector.

The purpose-defined CDD ends when the engagement is completed.

However, it must be for a minimum of 18 months and a maximum of 36 months.

It cannot be renewed.

The purpose-defined CSD shall be established in writing.

It includes the mandatory clauses for traditional CSDs.

The contract shall also specify the following information:

  • Mention fixed-term contract with a defined purpose
  • Title and references of the collective agreement establishing the contract
  • Description of the project at the origin of the contract, expected duration, definition of the corresponding tasks
  • Objective event or result determining termination of the contract
  • Deadline for anticipating the arrival of the end of the contract or the continuation of the employment relationship on a permanent contract
  • Mention of the possibility of termination of the contract by the employer or the employee, for a real and serious reason
  • Mention of the right of the employee to compensation equal to 10% of his gross total remuneration, in the event of breach of contract by the employer

The employee shall be entitled to the following guarantees:

End Date

A time limit must be observed between the decision to terminate the fixed-term contract and the actual termination of the employment contract.

This period is referred to as consideration is set at a minimum of 2 months.

Early rupture

The defined purpose of the CDD may be terminated at the initiative of the employer or employee.

It must be terminated for a real and substantial reason (i.e. based on objective, verifiable facts and not on subjective impression or judgment) under the following conditions:

  • Either 18 months after its conclusion (or at the end of the minimum period)
  • Each year on the anniversary date of signature of the contract


At the end of the contract, the employee is entitled to an indemnity equal to 10% of its gross total remuneration.

Compensation shall not be payable if the fixed-purpose fixed-term contract continues with a fixed-term contract.

Compensation remains due to the employee when the early termination is at the employer's initiative. If the employee decides to terminate the contract, the compensation is not due.
