CDI vs CDD: Legal and Practical Differences
CDI vs CDD: Legal and Practical Differences
The choice between a permanent contract (CDI) and a fixed-term contract (CDD) constitutes a major strategic decision for any employer. These two contractual forms, although regulated by the French Labor Code, respond to distinct logics and imply different obligations. Understanding their legal and practical specificities allows HR services to secure their recruitment and optimize their human resources management policy.
The permanent contract: the normal and general form of the employment contractIn accordance with article L1221-2 of the Labor Code,the permanent contract is the normal and general form of the employment relationship ⬥⬥⬥. It has no end date and offers the employee maximum job stability. The employer is committed to a long-term relationship, which implies strict procedures in the event of termination: dismissal for personal or economic reasons, conventional termination, resignation or retirement.
The permanent contract can be concluded full-time or part-time, and generally begins with a trial period (2 to 4 months depending on the professional category, renewable once). Its written drafting is not obligatory, except in certain cases (part-time work, specific clauses), but it remains strongly recommended to secure the employment relationship.

- The fixed-term contract can only be concluded for the execution of a specific and temporary task, in the cases exhaustively listed in article L1242-2 of the Labor Code:
- Replacement of an absent employee
- Temporary increase in activity
- Seasonal or customary employment
Supported contracts (apprenticeship, professionalization)Itsmaximum duration is generally 18 months ⬥⬥⬥, renewals included (up to two times). The contract must be written and sent to the employee within 2 working days following hiring, under penalty of reclassification as a permanent contract (article L1242-13).

Practical differences for the employer
Failure to comply with these rules exposes the employer tocivil sanctions(requalification to permanent contract, payment of compensation) and(requalification to permanent contract, payment of compensation) andcriminal sanctions
(fine up to €3,750, doubled in case of recurrence).
Choose the right contract according to your needs
The use of fixed-term contracts must always be justified by an objective and temporary reason. In case of doubt, the CDI remains the most legally secure solution. Companies favoring abusive fixed-term contracts are exposing themselves to growing labor disputes, with judges applying a strict interpretation of authorized appeal cases.HR managers must also anticipate the impact of fixed-term contracts on theemployer unemployment insurance contribution ⬥⬥⬥, which can be modulated according to the rate of termination of short contracts (bonus-malus since 2021).
