Probationary Period: Legal Duration and Termination

Introduction

The probationary period is one of the contractual clauses most poorly understood by both employers and employees. Yet its rules are strictly regulated by the Labour Code: maximum duration according to professional category, renewal conditions, notice periods to be observed when terminating the probationary period. An error in drafting a contract or in the procedure for ending a probationary period can be costly, both in terms of employment tribunal claims and HR management. This article reviews the legal durations applicable in 2026, the modalities of renewal, the rules of termination and how electronic signature for HR modernises and secures these contractual procedures.

Legal Duration of Probationary Period by Professional Category

The maximum durations of the probationary period in permanent contracts (CDI) are set out in Article L1221-19 of the Labour Code. They vary depending on the employee's socioprofessional category.

Permanent Contracts: Durations by Category

For a permanent employment contract, the maximum initial durations are as follows:

• Manual workers and clerical staff: 2 months

• Supervisory staff and technicians: 3 months

• Managers: 4 months

These durations are legal ceilings. A collective agreement or sectoral agreement may provide for shorter durations, but never longer than those set by law — except for a collective arrangement prior to 26 June 2008 (the date of the Labour Market Modernisation Act) which had established longer durations, which then remain applicable.

Fixed-term Contracts: Proportional Logic

For fixed-term employment contracts, the probationary period is proportional to the total duration of the contract. According to Article L1242-10 of the Labour Code, it is calculated at the rate of one day per week of contract, limited to:

• 2 weeks for a fixed-term contract of 6 months or less

• 1 month for a fixed-term contract of more than 6 months

It is important to note that the probationary period must be expressly stipulated in the employment contract. In the absence of explicit contractual mention, no probationary period can be imposed on the employee.

Temporary Work and Specific Contracts

For temporary employment contracts (agency work), the duration of the probationary period is set at:

• 2 working days for a mission of less than 1 month

• 3 working days between 1 and 2 months

• 5 working days beyond 2 months

These rules apply independently of the sectoral collective agreement.

Renewal of Probationary Period: Conditions and Limits

Renewal of the probationary period is not automatic. It is subject to three cumulative conditions provided for in Article L1221-21 of the Labour Code.

Three Legal Conditions for Renewal

• A collective agreement or sectoral agreement must expressly authorise it. In the absence of such a provision, renewal is impossible.

• Renewal must be expressly provided for in the employment contract. A mere oral mention is insufficient.

• The employee must give explicit agreement before the end of the initial period. Implied or presumed agreement is insufficient.

In practice, the maximum duration of the probationary period including renewal is:

• 4 months for manual workers and clerical staff

• 6 months for supervisory staff and technicians

• 8 months for managers

These total durations are absolute limits: even a favourable collective agreement cannot exceed them.

Beware of Abusive Clauses

The Court of Cassation has reminded on several occasions (notably Cass. soc., 23 January 2013, No. 11-23.428) that a clause which extends the probationary period beyond legal limits is void as of right. An employer who relies on such a clause to terminate the contract risks reclassification as dismissal without real and serious cause.

Termination of Probationary Period: Notice Periods and Formalities

Termination of the probationary period is free under law: neither the employer nor the employee must justify their decision. However, it must comply with notice periods and certain formalities.

Notice Periods in Permanent Contracts

Since the Act of 25 June 2008, Articles L1221-25 and L1221-26 of the Labour Code impose minimum notice periods depending on the employee's length of service at the time of termination.

At the Initiative of the Employer:

• Less than 8 days of service: 24 hours

• Between 8 days and 1 month: 48 hours

• Between 1 and 3 months: 2 weeks

• Beyond 3 months: 1 month

At the Initiative of the Employee:

• Less than 8 days of service: 24 hours

• From 8 days onwards: 48 hours

Failure by the employer to comply with these periods entitles the employee to compensatory damages, without this affecting the validity of the termination.

Formality of Notification

Although the law does not require any particular form for notifying the end of the probationary period, prudence requires formalising the termination in writing. Electronic signature in the enterprise makes it possible to secure this notification: the date of sending is certified, consent is traced, and the document is time-stamped in accordance with the eIDAS regulation.

The use of an eIDAS-compliant electronic signature tool ensures in particular that the employer can prove, in the event of dispute, the exact date on which the notification was sent to the employee — a determining factor for calculating notice periods.

Cases of Suspension: Illness, Work Accident

The probationary period may be suspended in the event of the employee's absence (illness, paid leave, work accident). The Court of Cassation established this principle of suspension-extension in a judgment of 4 February 2015 (No. 13-28.229). The probationary period resumes for the remaining duration following the absence, without exceeding legal limits.

This rule is important: an employee whose probationary period would have ended during sick leave cannot be terminated on that basis during their absence.

Digitalisation of Employment Contracts and Probationary Period

Paper management of employment contracts, amendments renewing probationary period and termination notices is a major source of documentary risk. Postal delays, loss of mail and difficulties in proving the date of receipt are issues regularly raised in employment tribunal litigation.

Probative Value of Electronic Signature in Employment Law

Since Ordinance No. 2017-1387 of 22 September 2017 and the case law resulting from it, the employment contract may validly be concluded and signed in electronic form. Advanced or qualified electronic signature within the meaning of the eIDAS regulation confers on the document a probative value equivalent to that of a handwritten signature, provided that the process used guarantees the identification of the signatory and the integrity of the document.

Concrete Benefits for HR Teams

HR teams relying on a certified electronic signature solution generally see a reduction of 60 to 80% in the time spent on administrative management of employment contracts (source: Markess / PAC sectoral reports, 2023-2024). Beyond the time saving, complete traceability of the signing process — who signed, when, from which device — constitutes solid evidence in case of dispute over the date of commencement or end of probationary period.

Integration with HRIS Tools

Modern solutions like Certyneo integrate with the main HR information systems on the market (Workday, SAP SuccessFactors, Lucca, Silae) via REST API. This interconnection allows automatic triggering of contract sending for signature as soon as a recruitment is validated in the HRIS, real-time monitoring of signature status, and archiving of signed documents in an electronic safe deposit box compliant with NF Z42-020 standard.

Legal Framework Applicable to the Probationary Period

The probationary period is principally governed by the Labour Code, Articles L1221-19 to L1221-26 for permanent contracts, and L1242-10 for fixed-term contracts. These provisions were fundamentally reformed by Act No. 2008-596 of 25 June 2008 on the modernisation of the labour market, which established uniform legal durations and mandatory notice periods.

Reference Texts:

• Article L1221-19 of the Labour Code: maximum initial durations of the probationary period in permanent contracts according to professional category

• Article L1221-21 of the Labour Code: cumulative conditions for renewal (collective agreement, contractual provision, employee consent)

• Articles L1221-25 and L1221-26 of the Labour Code: notice periods applicable to termination of the probationary period at the initiative of the employer or employee

• Article L1242-10 of the Labour Code: duration of the probationary period in the context of a fixed-term contract

On the Legal Value of Electronic Contracts and Digital Notification:

• eIDAS Regulation No. 910/2014 (EU): establishes levels of electronic signature (simple, advanced, qualified) and their cross-border probative value

• Articles 1366 and 1367 of the Civil Code: establish the principle of equivalence between electronic writing and paper writing, provided that the process guarantees the identity of the signatory and the integrity of the document

• Ordinance No. 2017-1387 of 22 September 2017: authorises the use of electronic signature for employment contracts

• GDPR No. 2016/679: applies to the processing of personal data of signatories (name, e-mail, biometric data if applicable) in the context of the electronic signature process

• Standard ETSI EN 319 132: technical specification relating to advanced electronic signature formats XAdES, applicable to contractual documents

Legal Risks:

An excessive probationary period or non-compliant renewal exposes the employer to reclassification as dismissal without real and serious cause (Cass. soc., 23 January 2013). Failure to comply with notice periods generates compensatory damages due as of right. The absence of written evidence of termination notification may lead to dispute over the date of termination, with consequences for calculating severance and notice period. Using a certified electronic signature solution makes it possible to constitute a time-stamped and inalterable proof, enforceable before employment tribunals.

Use Cases

Scenario 1 — An IT Services SME Managing Multiple Hirings Simultaneously

An SME of around fifty employees in the IT services sector recruits on average 15 to 20 collaborators per year, of which a significant proportion are managers. Paper management of employment contracts caused frequent delays: contracts sent by post, return signature delays of 5 to 10 working days, risks of document loss. By switching to an advanced electronic signature solution compliant with eIDAS, the SME reduced the average time for signing employment contracts to less than 24 hours. The start date of the probationary period is now certified time-stamped to the nearest minute, which eliminates any potential dispute over the starting point for calculating legal periods. The time-saving benefit estimated by the HR team is around 70% on this specific task, equivalent to 3 to 4 days of work saved per month.

Scenario 2 — A Recruitment Intermediary Managing Fixed-term and Temporary Contracts

A firm specialising in recruitment and temporary personnel management, handling around 400 fixed-term contracts per year in the logistics and distribution sectors, faced a recurring problem: notice periods for terminating probationary periods were difficult to document. In case of dispute, the user employer struggled to prove the exact date on which the notification was delivered to the employee. After deploying an electronic signature solution with certified notification, the firm was able to create a complete proof file for each probationary period termination: date of sending, date of message opening, identity of recipient. Over 18 months, no employment tribunal disputes related to a contested notification date were recorded, compared to 3 to 4 cases per year previously.

Scenario 3 — A Group Association in the Medico-Social Sector with High Staff Turnover

A group association in the medico-social sector employing around 300 full-time equivalents manages a high turnover rate and many hires in permanent and short-term fixed contracts. The multiplicity of applicable collective agreements (CCN 66, CCN 51) complicates verification of maximum probationary period durations. By integrating a contract generator parameterised according to the collective agreement and employee status, combined with an electronic signature solution, the group automated verification of legal durations from contract drafting. Parameterisation errors — such as a 3-month probationary period inserted for an employee covered by an agreement limiting the duration to 2 months — were reduced to zero within less than 6 months of use.

Conclusion

The probationary period is a precise legal mechanism in which each parameter — initial duration, renewal conditions, notice periods — is strictly regulated by the Labour Code and social case law. Incorrect application of these rules exposes the employer to real and costly employment tribunal risks. Digitalisation of employment contracts via electronic signature is now the best way to secure these procedures: proof of date, traceability, eIDAS compliance and reliable archiving.
