How to Extend a Probation Period in France (Période d’Essai)

In France, the période d’essai (probation period) on an employment contract serves the same function as a probation in any other jurisdiction — both employer and employee can terminate the relationship more easily during this initial period. But French law constrains the maximum duration of the probation, and extension is only possible if the collective bargaining agreement (convention collective) and the original employment contract both permit it. This article, from a Gyoseishoshi (行政書士) document-preparation perspective, explains how to extend a probation period lawfully under the Code du travail articles L. 1221-19 to L. 1221-26, with all the relevant source URLs.

1. The statutory maximum durations

Under Code du travail article L. 1221-19, the maximum initial period d’essai for an indefinite-term contract (CDI) is:

Under Code du travail article L. 1221-21, the period d’essai may be renewed once if:

• The employment contract expressly provides for renewal, AND
• The convention collective authorizes renewal

After renewal, the total maximum duration (initial + renewal) is:

For fixed-term contracts (CDD) under article L. 1242-10, the maximum probation is calculated proportionally to the contract length, capped at 1 month for contracts of 6 months or more.

2. The two-condition rule for extension

The Cour de cassation has been consistent: a probation extension is valid only if both conditions are met:

1. The employment contract expressly states the possibility of renewal of the period d’essai
2. The convention collective (industry-wide collective bargaining agreement) authorizes renewal of the period d’essai for the relevant category of employee

If the contract is silent on renewal, the probation cannot be extended even if the convention collective allows it. If the convention collective is silent or prohibits renewal, the probation cannot be extended even if the contract allows it.

3. Step 1 — Verify the convention collective

Identify which convention collective applies to your business. The convention is determined by the industry classification (code APE / NAF) of the employer. The convention is referenced:

• On the employee’s pay slip
• On the employer’s company-information page
• At the employee’s workplace (mandatory display under article R. 2262-3)

The convention collective text is available at:

Primary source — Legifrance conventions collectives: https://www.legifrance.gouv.fr/conv_coll/

Read the convention’s article on probation (typically titled “période d’essai” or in a chapter on contract formation) and confirm it permits renouvellement (renewal) for the employee’s category.

4. Step 2 — Verify the original contract permits renewal

The original employment contract must contain language expressly authorizing extension. Common compliant wording:

“La période d’essai pourra être renouvelée une fois pour une durée de [X] mois, conformément à l’article L. 1221-21 du Code du travail et à la convention collective applicable. Le renouvellement devra faire l’objet d’un accord écrit du salarié, au plus tard avant l’expiration de la période d’essai initiale.”

If the contract simply states a probation duration without referencing renewal possibility, renewal is not available — the contract must be amended (with the employee’s consent) before any extension can be considered, which is rarely possible mid-probation.

5. Step 3 — Obtain the employee’s express written consent before initial probation expires

This is the make-or-break step. The Cour de cassation requires:

• Written consent from the employee
• Express consent (not implied from continued work)
• Before the expiration of the initial probation period

A consent obtained on the day the initial probation expired (or after) is invalid — the probation has already terminated and the employee is now on indefinite contract with full notice protections.

The consent should be on a separate written document (not just a clause in the contract). A standard format:

“Je soussigné(e) [Employee name], après lecture de l’avenant à mon contrat de travail, accepte expressément le renouvellement de ma période d’essai pour une durée de [X] mois, à compter du [date], conformément à l’article L. 1221-21 du Code du travail et à la convention collective [name]. La période d’essai prendra ainsi fin le [date].”

Date and signature.

Best practice is to deliver the avenant (amendment) and consent form at least one week before the initial probation expires, allowing the employee to consider and sign without time pressure.

6. Step 4 — Document the renewal in writing

Both the employer and employee should retain:

1. The original employment contract (with the renewal-permission clause)
2. The relevant article of the convention collective in effect at the time of renewal
3. The signed avenant or written consent extending the probation
4. The pay slip(s) reflecting the extended probation status

If a dispute arises (employee terminated late in the extended probation), the conseil de prud’hommes (labour court) will require all four documents.

7. Termination during the extended probation

During the extended probation, either party may terminate without cause but must observe the notice periods in Code du travail article L. 1221-25:

Failure to give the required notice does not void the termination but exposes the terminating party to damages equal to the unpaid notice period.

8. Common errors that void the extension

A void extension means the employee is on indefinite contract with full notice protection from the day the initial probation should have ended. Termination after that point requires a valid reason (real and serious cause — cause réelle et sérieuse) and proper procedure under article L. 1232-1 et seq. Damages for wrongful termination can substantially exceed the avoided probation extension.

9. Special cases

Apprenticeship contracts (contrat d’apprentissage)

Under article L. 6222-18, the period d’essai for apprenticeship is fixed at the first 45 days (skill weeks). It cannot be extended.

Internship (stage)

Internship is not a regular employment contract; it operates under different rules (convention de stage). Probation does not apply.

Work-study contracts (contrat de professionnalisation)

Under article L. 6325-1, the period d’essai follows the regular CDI / CDD rules in articles L. 1221-19 et seq., subject to the contract type.

Senior cadre / executive positions

For very senior cadre positions, the convention collective often allows the maximum 8-month probation (4 months + 4 month renewal). Compliance is critical because executive terminations are heavily litigated.

10. Practical drafting tips

When preparing the original contract:

1. Include explicit renewal language if there is any chance the role might benefit from extension
2. Reference the applicable convention collective by name and date in the contract
3. State the proposed renewal duration precisely (e.g., “2 months” rather than “a reasonable period”)
4. Include the requirement of written consent before initial expiration in the contract clause itself

When preparing the renewal avenant:

1. Send the avenant at least 7 days before initial probation expires
2. Use a standalone document (not a casual email)
3. Have the employee sign and date in handwriting (or with verified e-signature)
4. Retain the signed original in the employee’s file

11. Inspection by Inspection du travail

The Inspection du travail (labour inspection) may audit probation extensions during routine business inspections. Issues that draw scrutiny:

• Repeated extensions of multiple employees in similar circumstances
• Extensions that conveniently align with restructuring or layoffs
• Extensions after the initial period had clearly expired

Documentation matters here too — a clean signed avenant with the convention collective reference defuses most labor inspection concerns.
