Probationary Period: Legal Deadlines and Termination

Introduction

The probationary period is a pivotal phase of the employment contract: it allows the employer to assess the employee's skills and the latter to appreciate their new working conditions. Governed by articles L.1221-19 to L.1221-26 of the Labour Code, it complies with precise rules regarding duration, renewal and termination conditions. Any failure to comply with these legal deadlines exposes the company to costly employment tribunal disputes. In this article, we review the legal durations applicable according to professional category, renewal procedures, mandatory notice periods and best practices for formalising and securing the termination of the probationary period.

Legal Durations of the Probationary Period under the Labour Code

The maximum durations of the probationary period have been set by law since the 2008 reform (Law No. 2008-596 of 25 June 2008). They vary depending on the professional category of the employee recruited on a permanent contract (CDI).

Legal Durations for Permanent Contracts (CDI)

• Workers and clerical staff: 2 months

• Supervisory staff and technicians: 3 months

• Managers: 4 months

These durations are legal maxima. A collective agreement or sectoral agreement may provide for shorter durations — never longer, except for collective provisions prior to the 2008 law expressly maintained. It is therefore necessary to systematically consult the applicable collective agreement before drafting the employment contract.

Special Case of Fixed-Term Contract (CDD)

For CDDs, the duration of the probationary period is proportional to the contract duration: one day per week with a maximum of two weeks for contracts of six months or less, and one month for contracts exceeding six months. The electronic signature of employment contracts now makes it possible to formalise these clauses immediately, with time-stamping and archiving in a legally reliable manner.

Probationary Period and Work-Study or Apprenticeship Contract

Apprenticeship contracts do not contain a probationary period in the strict sense. However, the first two months of the contract constitute a period during which either party may terminate without any particular formality. The work-study contract follows the rules of the CDD or CDI depending on its nature.

Renewal of the Probationary Period: Conditions and Formalities

Renewal of the probationary period is only possible if three cumulative conditions are met:

• A collective agreement or sectoral agreement expressly authorises it.

• The employment contract must explicitly mention the possibility of renewal from its conclusion.

• The express agreement of the employee must be obtained before the end of the initial period.

Maximum Durations after Renewal

After renewal, total durations cannot exceed:

• Workers and clerical staff: 4 months

• Supervisory staff and technicians: 6 months

• Managers: 8 months

These ceilings are of public policy: no individual agreement can exceed them. A renewal made without the express agreement of the employee or beyond these durations will be reclassified by employment tribunals, exposing the employer to damages. To secure this agreement, the use of a tool compliant with eIDAS electronic signature regulation guarantees an irrefutable audit trail.

The Notion of Fictitious Probationary Period

The case law of the Court of Cassation regularly sanctions employers who abusively extend the probationary period to defer protections linked to dismissal. An excessively long probationary period or one renewed without a collective basis may be reclassified as dismissal without genuine and serious cause.

Notice Periods upon Termination of the Probationary Period

Termination of the probationary period is free: neither the employer nor the employee need to justify it. However, mandatory notice periods apply under the 2008 law.

Notice Periods Borne by the Employer

When the employer terminates the probationary period, they must observe a notice period whose duration varies depending on the employee's length of service in the company:

• Less than 8 days of service: 24 hours

• Between 8 days and 1 month of service: 48 hours

• Between 1 and 3 months of service: 2 weeks

• Beyond 3 months of service: 1 month

These periods are calculated in calendar days. Failure to observe the notice period does not render the termination void but entitles the employee to compensation equal to the salary they would have received during this period.

Notice Periods Borne by the Employee

When it is the employee who takes the initiative to terminate the probationary period, they must notify the employer:

• 48 hours before their departure

• 24 hours if the period of service in the company is less than 8 days

These periods are considerably shorter, reflecting the freedom of mobility granted to the employee during the probationary period. Termination notification can be formalised by registered mail with acknowledgement of receipt or, increasingly, by qualified electronic signature, which provides a certain date and opposable proof.

Consequences of Non-Compliance with Notice Periods

Failure to observe notice periods by the employer constitutes a breach liable to engage its contractual liability. Since the ruling of the Social Chamber of the Court of Cassation of 5 November 2014 (No. 13-18.114), it is established that termination notified outside business hours and days may be deemed abusive if it reveals an intention to harm.

Formalities of Termination and Securing through Electronic Signature

Although the law does not impose any particular form for termination of the probationary period — it can theoretically be verbal — prudence recommends a dated and signed document. In practice, HR managers and company lawyers increasingly favour documented processes for several reasons.

Why Formalise Termination in Writing?

• Proof of notification date: the notice period runs from receipt of the notification. A time-stamped document avoids any dispute over the starting point.

• Proof of unequivocal intent: the Court of Cassation accepts verbal termination, but its proof is difficult to establish if the employee contests it.

• Maintenance of audit trail: secure electronic archives make it possible to instantly retrieve any document in the event of litigation.

Integration into a Digital HR Process

Electronic signature solutions dedicated to human resources make it possible to automate the sending, signature and archiving of documents related to the probationary period: renewal letter, express agreement of the employee, termination notice. The evidential value of an advanced or qualified electronic signature within the meaning of eIDAS Regulation (EU) No. 910/2014 is recognised by French courts, as recalled by the comprehensive guide to electronic signature in business.

For companies managing many simultaneous recruitments, the use of a electronic signature ROI calculator makes it possible to precisely quantify the HR productivity gains linked to the dematerialisation of these formalities.

Points of Particular Attention in 2026

Interaction between Probationary Period and Sickness Absence

Suspension of the employment contract due to prolonged illness extends the probationary period by the same amount, unless a collective provision provides otherwise. An employee absent for 15 days due to illness has their probationary period postponed by 15 calendar days. This rule, confirmed by the Court of Cassation (Soc., 28 April 2011, No. 09-40.487), is often overlooked by employers.

Non-Compete Clause and Probationary Period Termination

Termination of the probationary period ends the employment contract but does not necessarily eliminate a non-compete clause if it was validly stipulated. However, many sectoral agreements provide that the non-compete clause does not apply in the event of termination during the probationary period, subject to express waiver within the agreed deadlines.

Probationary Period and Confidentiality Agreement

When an employee has had access to sensitive information from the start of their employment in the company, termination of the probationary period does not eliminate confidentiality obligations. These commitments, ideally signed on the first day via a secure electronic signature solution, remain enforceable after the end of the contractual relationship.

Legal Framework Applicable to the Probationary Period

Labour Code

The probationary period is principally governed by articles L.1221-19 to L.1221-26 of the Labour Code, arising from Law No. 2008-596 of 25 June 2008 on modernisation of the labour market. These provisions set maximum durations, renewal conditions and notice periods. They have the force of public policy, meaning that no subsequent individual or collective agreement can derogate from them in a manner unfavourable to the employee — except collective agreements prior to the law expressly maintained.

Article L.1221-20 defines the probationary period as allowing the employer to assess the employee's competence in their work, and the employee to appreciate whether the functions suit them. Its inclusion in the contract is not automatic: it must be expressly stipulated, failing which the contract is considered definitive from employment.

Case Law of the Court of Cassation

The Social Chamber of the Court of Cassation has delivered several landmark rulings:

• Soc., 5 November 2014, No. 13-18.114: termination notified under humiliating conditions may constitute a breach causing distinct damage, even if the termination itself is free.

• Soc., 28 April 2011, No. 09-40.487: suspension of the contract due to illness postpones the expiry of the probationary period.

• Soc., 23 January 2013, No. 11-23.428: renewal without express agreement of the employee is unenforceable.

Evidential Value of Electronic Documents

In accordance with article 1366 of the Civil Code, an electronic document has the same evidentiary force as a paper document, provided that the identity of the person from whom it originates is duly assured and that the document is established and preserved under conditions to guarantee its integrity. Article 1367 of the Civil Code clarifies that an electronic signature consists of the use of a reliable identification method guaranteeing its link with the act to which it is attached.

The eIDAS Regulation (EU) No. 910/2014, applicable in French law, establishes three levels of electronic signature (simple, advanced, qualified). For routine HR documents such as probationary period renewal or termination letters, an advanced electronic signature is generally sufficient. The qualified signature, compliant with standards ETSI EN 319 132 and issued by a qualified trust service provider (QTSP), offers the highest presumption of reliability under the law.

GDPR and Candidate Data

Personal data collected during the probationary period (evaluations, exchanges, HR documents) are subject to Regulation (EU) 2016/679 (GDPR). The employer must inform the employee of the processing of their data, its duration of storage and their rights of access and erasure. The retention period for documents relating to termination is aligned with the employment tribunal limitation period, set at two years since the law of 14 June 2013.

Usage Scenarios: Formalising the Probationary Period with Electronic Signature

Scenario 1 — An Industrial SME of 150 Employees with High Operator Turnover

An industrial SME recruits on average 40 operators and supervisory staff per year. Each recruitment generates several documents to be signed: employment contract with probationary period clause, staff handbook, confidentiality agreement, and, where applicable, renewal or termination letter. With a paper process, the average time between the HR decision and the effective signature of the document was 4 working days, exposing the company to the risk of not complying with legal notice periods.

By deploying an advanced electronic signature solution integrated with its HRIS, the SME reduced this deadline to less than 2 hours. Each document is time-stamped, automatically archived and accessible in case of dispute. The error rate for notice periods fell to zero over the 18 months following deployment. According to HR estimates, the productivity gain represents approximately 1.5 full-time equivalent per year.

Scenario 2 — A Management Consulting Firm Managing Senior Profiles with High Turnover

A consulting firm of 80 consultants, most of whom are managers, experiences high turnover (approximately 25% per year). The probationary period for managers is 4 months, renewable once to 8 months provided there is sectoral agreement. The firm had experienced two employment tribunal disputes in three years relating to poorly formalised renewals: employee agreement obtained verbally or after expiry of the initial period.

Since adopting a digital workflow with electronic signature, each step is automatically triggered 15 days before the deadline: the employee receives an email offering them to electronically sign their renewal agreement, with a response deadline of 5 days. In the absence of signature, the probationary period is not renewed. This process has eliminated any dispute related to renewal since its implementation, representing an estimated saving of between €8,000 and €15,000 in legal advice and dispute resolution costs per year, according to the ranges published by sectoral HR benchmarks.

Scenario 3 — A Public Hospital Group Managing Multiple Facilities

A public hospital group of approximately 1,200 staff recruits several hundred public law contractors annually for nursing and administrative positions. Although public law is not subject to the Labour Code, the probationary periods of contractor staff are governed by Decree No. 86-83 of 17 January 1986, which provides for comparable durations and termination procedures. The dematerialisation of probationary period completion letters (functional equivalent of probationary period termination) reduced processing time from 6 days to 1 working day, while guaranteeing the audit trail required by regional Court of Auditors audits.

Conclusion

The probationary period is a precise legal mechanism that allows no room for approximation: maximum durations set by law, renewal subject to a triple agreement, mandatory notice periods calculated to the day. Any procedural error can turn into costly employment tribunal litigation, with reclassification as dismissal without genuine and serious cause.

The good news is that the dematerialisation of HR processes — notably through the use of electronic signature — now makes it possible to automate these formalities whilst guaranteeing their evidential value. Each document is time-stamped, archived and enforceable.
