Probationary Period: Legal Duration and Termination

The probationary period is a fundamental contractual phase in the employment relationship: it allows the employer to assess the employee's skills, and conversely allows the employee to verify if the position suits them. Yet its rules — maximum durations, renewal conditions, notice periods for termination — are sources of numerous disputes before the employment courts. In 2025-2026, the digitalisation of HR processes, particularly through electronic signatures for HR, is transforming the way contracts including the probationary period are concluded and archived. This guide presents the complete legal framework, pitfalls to avoid and best practices to secure your hires.

Legal Durations of the Probationary Period by Contract Type

The duration of the probationary period varies depending on the nature of the employment contract and the professional category of the employee. These durations are fixed by the Labour Code and cannot be exceeded, except where a collective agreement provides more favourable terms for the employee.

Permanent Contract (CDI)

Since the labour market modernisation law of 25 June 2008, the maximum durations of probationary period for permanent contracts are clearly established:

• Manual workers and employees: 2 months

• Supervisors and technicians: 3 months

• Managers: 4 months

These durations are measured in calendar time, unless otherwise provided by the applicable collective agreement. Note: suspension of the probationary period (due to illness, work accident or paid leave taken at the employer's initiative) extends the initial duration accordingly.

Fixed-term Contract (CDD)

For fixed-term contracts, the duration of the probationary period is proportional to that of the contract:

• For contracts of 6 months or less: 1 day per week worked, up to a maximum of 2 weeks

• For contracts exceeding 6 months: 1 month maximum

The Court of Cassation (Soc., 13 November 2019, n°18-15.442) clarified that any clause fixing a longer duration is deemed not written.

Special Contracts: Apprenticeship and Professionalisation

The apprenticeship contract provides for a probationary period of 45 days, during which either party may terminate freely. After this period, termination is subject to much more restrictive rules. The professionalisation contract follows the rules of fixed-term or permanent contracts depending on the form chosen.

Renewal of the Probationary Period: Conditions and Limits

Strictly Regulated Renewal

The probationary period of a permanent contract is renewable only once, subject to three cumulative conditions set out in article L.1221-21 of the Labour Code:

• An extended sectoral agreement must expressly provide for it

• The employment contract or engagement letter must mention the possibility of renewal

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

The employee's agreement cannot be presumed or tacit. Mere silence or failure to formally object does not constitute valid consent according to consistent case law. To secure this renewal, many employers today opt for eIDAS-compliant electronic signatures, which precisely timestamp consent and produce irrefutable evidence.

Maximum Durations After Renewal

With renewal, the total maximum durations are:

• Manual workers and employees: 4 months

• Supervisors and technicians: 6 months

• Managers: 8 months

Any probationary period exceeding these limits is void ab initio, which may transform a termination into dismissal without real and serious cause, with associated compensation consequences.

Termination of the Probationary Period: Procedure and Notice Periods

Termination at Employer's Initiative

The employer may terminate the probationary period without having to justify the decision and without following disciplinary procedures. However, the termination must not be abusive, discriminatory or based on an unlawful ground (health status, pregnancy, union activity, etc.). In the case of abusive termination, the employee may obtain damages before the employment court.

The notice periods that the employer must observe are set out in article L.1221-25 of the Labour Code:

• Less than 8 days' service: 24 hours

• Service between 8 days and 1 month: 48 hours

• Service between 1 and 3 months: 2 weeks

• Service exceeding 3 months: 1 month

If the employer fails to observe these periods, they must pay compensation equal to the duration of unserved notice.

Termination at Employee's Initiative

An employee wishing to terminate their probationary period has a notice period of 48 hours, reduced to 24 hours if service is less than 8 days. No justification is required, and no termination allowance is due. The termination takes the form of simple written notification, preferably by registered letter with acknowledgement of receipt or — an increasingly common solution — via electronic signatures for business contracts allowing immediate archiving.

Special Cases: Protected Employee and Pregnant Employee

The probationary period is not incompatible with protected status, but termination is subject to enhanced rules. For a staff representative whose mandate arises during the probationary period, termination requires authorisation from the labour inspector. For an employee whose pregnancy is declared, termination is void as soon as the employer becomes aware of it (article L.1225-4 of the Labour Code).

Digitalisation of Contracts and Securing the Probationary Period

The Value of Electronic Signatures in HR Management

Advanced or qualified electronic signatures, compliant with the eIDAS Regulation No. 910/2014, provide threefold added value for managing probationary periods:

• Certified timestamp: the date of signing the contract and any renewal amendment is incontestable

• Probative archiving: the electronically signed document has the same legal value as a paper document (article 1366 of the Civil Code)

• Consent traceability: essential to prove that the employee expressly accepted the renewal of their probationary period

Modern SaaS solutions allow these flows to be integrated into existing HRIS via API, reducing administrative onboarding time by an average of 70% according to sector feedback from 2024-2025. For more information, the electronic signature ROI calculator allows you to estimate concrete gains for your organisation.

Compliant Contract Templates and Best Practices

The use of pre-established contract templates to download and regularly updated in light of legislative changes significantly reduces the risk of drafting error. A poorly worded contract — forgetting to mention the possibility of renewal, or setting an excessive duration — can invalidate the entire probationary period and expose the employer to an employment court ruling.

Key points to watch when drafting:

• Explicitly mention the duration of the probationary period and the possibility of renewal if the applicable collective agreement permits it

• Specify the professional category to justify the chosen duration

• Include an electronic archiving clause for any subsequent modifications

Legal Framework Applicable to the Probationary Period

The probationary period is governed by a set of legislative and regulatory texts that employers and employees must master to avoid any dispute.

Labour Code — Main Provisions

• Article L.1221-19: sets the maximum durations of probationary period for permanent contracts by professional category (2 months manual workers/employees, 3 months supervisors/technicians, 4 months managers).

• Article L.1221-20: recalls that the collective agreement may provide for shorter durations, more favourable to the employee.

• Article L.1221-21: strictly regulates renewal (extended sectoral agreement, contractual mention, express employee agreement).

• Article L.1221-24: provides rules for counting the duration of the probationary period where employment follows a work placement.

• Article L.1221-25: requires notice periods in case of termination at the employer's initiative.

• Articles L.1225-4 and L.1225-5: protect the pregnant employee against any termination of the probationary period once pregnancy is known.

Legal Value of Electronically Signed Contracts

• Article 1366 of the Civil Code: "An electronic document has the same evidential force as a document on paper, provided that the person from whom it emanates can be duly identified and that it is established and preserved in conditions such as to guarantee its integrity."

• Article 1367 of the Civil Code: defines electronic signature as "the use of a reliable identification process guaranteeing its link with the act to which it is attached".

• eIDAS Regulation No. 910/2014 (EU) — and its successor eIDAS 2.0 currently being deployed — establishes three levels of electronic signature (simple, advanced, qualified) with a legal presumption of reliability for qualified signatures (article 25, §2).

GDPR and Processing of Candidate Data

The Regulation (EU) 2016/679 (GDPR) applies from the moment personal data is collected during recruitment. The employer must:

• Inform the employee of the purpose of processing their data in the contract

• Limit data retention to necessary periods (in practice, employment court limitation period: 3 years for wage claims, 5 years for liability actions)

• Ensure that electronic signature providers comply with GDPR (EU hosting, signed DPA)

Key Case Law

• Cass. Soc., 13 November 2019, n°18-15.442: any fixed-term contract probationary period exceeding the legal limit is void

• Cass. Soc., 26 November 2020, n°19-15.737: tacit renewal of the probationary period is void

• Cass. Soc., 8 April 2021, n°19-14.605: discriminatory termination during probationary period entitles the employee to damages

Concrete Use Scenarios

Scenario 1 — SME of 45 Employees Managing Frequent Hires

A digital services SME hiring around twenty employees per year faced a dual problem: employment contracts drafted with incorrect probationary durations for the manager category (3 months instead of 4), and lack of formal proof of consent to renewal. After two employment court rulings in two years, the HR department implemented an advanced electronic signature flow for all employment contracts. Result: zero disputes over contract form in 18 months, average signature time reduced from 5 days to under 4 hours, and automatic archiving in the HRIS with certified timestamp. The estimated HR productivity gain represents approximately 2 working days per month.

Scenario 2 — Industrial Group Renewing Probationary Periods for Senior Managers

A mid-sized industrial group (approximately 600 employees) was renewing probationary periods for senior managers through simple email exchanges, with no clear traceability of the employee's express agreement. Following advice from the internal legal team highlighting the risk, the group deployed a SaaS electronic signature solution integrated into its HRIS. Each renewal request now generates a structured document electronically signed by both parties before the expiry of the initial period, with proof of dispatch and timestamped acceptance. This process has reduced the risk of renewal invalidation by 90% and simplified annual HR audits.

Scenario 3 — Recruitment Firm Managing Successive Fixed-term Contracts for Clients

A firm specialising in the temporary recruitment of technical profiles assists its SME/microbusiness clients in drafting and managing fixed-term contracts. These contracts of 3 to 6 months systematically include a proportional probationary period, whose calculation is a frequent source of errors (confusion between business and calendar days). The firm integrated a contract generator parameterised by CDD duration, combined with an electronic signature solution, allowing its clients to sign and archive contracts in less than an hour. Automatic reminders before expiry of the probationary period allow managers to anticipate the decision to terminate or confirm in 100% of cases, versus 60% previously.

Conclusion

The probationary period represents a key moment in the employment relationship, subject to a precise legal framework that every employer must master: maximum durations by professional category, strict renewal conditions, mandatory notice periods in case of termination. Errors in this area expose you to costly disputes and the reclassification of termination as dismissal without real and serious cause.

The digitalisation of contract management — particularly through eIDAS-compliant electronic signatures — provides a practical answer to these challenges: certified timestamp, proof of consent, probative archiving. These tools are no longer reserved for large corporations; they are accessible to all organisations, regardless of size.
