France Conventions Collectives: How They Apply to Your Contract

In France, the employment contract is just one layer of a multi-tier set of rules that govern an employer-employee relationship. Above the contract sits the convention collective de branche — the sectoral agreement that applies to every employer in the relevant industry, regardless of whether the employer signed up to it directly. Understanding which convention collective applies to your business — and what it requires — is one of the most fundamental compliance steps in French employment law. This article walks through the framework.

1. The Hierarchy of Sources

Under the Code du travail, employment relationships are governed by a hierarchy of legal sources. The principle of “ordre public social” means that lower-level rules (closer to the employer) cannot derogate from higher-level rules to the disadvantage of the employee — unless the higher rule explicitly permits it.

The hierarchy:

1. Constitutional norms and treaties — French Constitution, EU treaties, ILO conventions.
2. Code du travail (statutory).
3. Décrets and arrêtés (regulatory).
4. Convention collective interprofessionnelle nationale (ANI) — e.g., ANI on mutuelle santé.
5. Convention collective de branche — sectoral agreement.
6. Accord d’entreprise — company-level agreement.
7. Accord d’établissement — establishment-level agreement.
8. Usage / engagement unilatéral — custom or unilateral commitments.
9. Contrat de travail individuel — individual contract.

The Loi Travail 2016 (“Loi El Khomri”) and Ordonnances Macron 2017 changed the precedence on certain matters — for some topics (e.g., overtime, breaks), the accord d’entreprise can prevail over the convention collective de branche, even if less generous to the employee. But for core matters (minimum wage, classifications, employer-paid mutuelle, prévoyance, vocational training, equality), the convention collective de branche remains supreme.

2. The Convention Collective de Branche

A convention collective de branche is a comprehensive sectoral agreement negotiated between:

• Employer federations representing the industry (e.g., MEDEF or FBF for banking).
• Trade unions (CFDT, CGT, FO, CFE-CGC, CFTC).

A convention collective de branche typically covers:

• Salary scales (minimum salaries by classification level).
• Job classifications (engineers, technicians, employees, workers).
• Working time arrangements (sometimes more generous than the 35h/week statutory baseline).
• Annual leave (often 25 working days but can be more — e.g., 30+ days in finance).
• Sick pay (employer top-up to the statutory IJSS for a defined number of days).
• Probation period (essais).
• Notice periods for resignation and dismissal.
• Severance pay (often higher than statutory minimum).
• Rules on overtime, on-call duty, shift work.
• Mandatory training (formation continue).
• Professional development (entretiens annuels, gestion des compétences).

There are around 400 active conventions collectives in France, identified by their IDCC code (Identifiant des Conventions Collectives). Examples:

• IDCC 1486 — Bureaux d’études techniques (Syntec) — covers IT, consulting, engineering services.
• IDCC 1979 — HCR (hôtels, cafés, restaurants).
• IDCC 16 — Transport routier.
• IDCC 2098 — Personnel des prestataires de services (BPO, call centres).
• IDCC 1090 — Services automobiles.
• IDCC 2120 — Banques.

3. Identifying the Applicable Convention Collective

The applicable convention collective is determined by:

• The principal activity of the employer, identified by the APE/NAF code assigned by INSEE on company registration.
• Where the employer has multiple activities, the principal activity (highest turnover or headcount).
• For some industries, the geographic location may also be relevant.

The bulletin de paie must mention the applicable convention collective (Code du travail R.3243-1) — checking the bulletin is the first step.

The ministerial portal Légifrance provides searchable access to all conventions collectives by IDCC.

4. Extension and Élargissement

A convention collective de branche initially applies only to the employers and employees affiliated to the signatory federations. To bind all employers in the sector, the Minister of Labour must issue an arrêté d’extension under Code du travail L.2261-15.

Most major conventions collectives have been extended. So a small employer who has not joined any federation is still bound by the extended convention collective applicable to their NAF code.

For sectors not yet covered by a convention collective de branche, an arrêté d’élargissement can extend an existing convention to a related sector (Code du travail L.2261-17).

5. Application to Specific Topics

5.1 Salaries

The convention collective sets minimum salaries by classification level. These minimums are usually higher than the SMIC for skilled positions. For example, Syntec (IDCC 1486) sets a minimum for “Position 1.1” cadre that is well above the SMIC.

Salary increments may also be covered — annual salary review, performance-based increments, bonuses.

5.2 Annual Leave

The Code du travail provides 5 weeks (2.5 jours ouvrables per month). Many conventions collectives provide more, e.g., extra days for length of service, age, family responsibilities.

5.3 Probation Periods

The Code du travail caps probation at 2 months (employees), 3 months (technicians/agents de maîtrise), 4 months (cadres). A convention collective can shorten this; only a convention collective extended before 25 June 2008 can override this with a longer period.

5.4 Notice Periods

Statutory notice (Code du travail L.1234-1):

• Less than 6 months service: as fixed by usage or contract.
• 6 months to 2 years: 1 month.
• 2+ years: 2 months.

Many conventions collectives provide longer notice — e.g., 3 months for cadres in many industries.

5.5 Severance Pay

Statutory severance (Code du travail R.1234-2): 1/4 month’s salary per year for the first 10 years, 1/3 thereafter. Many conventions collectives provide more — e.g., banking and insurance conventions often provide 1/2 month per year.

5.6 Mutuelle Santé and Prévoyance

The sectoral level often provides specific mutuelle santé and prévoyance regimes that go beyond the statutory minimum.

6. The 13th-Month Salary

Many conventions collectives provide a 13ème mois — an annual bonus equal to one month’s salary, typically paid in December. This is not a statutory entitlement under the Code du travail; it derives from the convention collective or from company custom.

If the convention collective requires a 13ème mois, paying without it is a breach. Conversely, some employers voluntarily provide a 13ème mois even where not required.

7. The “Avantage Le Plus Favorable” Principle

Where multiple sources provide conflicting rules, the most favourable to the employee applies — except where statute explicitly permits derogation. So if:

• Statute provides 5 weeks leave;
• Convention collective provides 6 weeks leave;
• Contract provides 7 weeks leave;

The employee gets 7 weeks (the most favourable).

But if the conflicting rule operates in the direction less favourable to the employee, the rule violating “ordre public social” is invalid and the higher-level rule prevails.

8. The Convention Collective at Hiring

When hiring, the employer must:

• Apply the convention collective minimum salary for the relevant classification.
• Provide the contract with mention of the convention collective and IDCC.
• Provide a copy of the convention collective (or notice of where it can be consulted) to the employee.
• Apply the convention’s probation period and notice period.
• Apply any specific clause required by the convention (e.g., mobility, confidentiality).

A new hire who later discovers the wrong convention was applied has 5 years to bring a wage-arrears claim under prescription extinctive (Code du travail L.3245-1).

9. Common Mistakes — Gyoseishoshi View

• Not identifying the IDCC. The single most common error. Without the IDCC, no informed compliance is possible.
• Applying the convention only to “cadres”. It applies to all employees in the company, not just executives.
• Misclassifying employees. A “non-cadre” classified as cadre to avoid certain rules — challengeable by URSSAF and tribunal.
• Missing 13ème mois. A €36,000 salary employee not getting €3,000 for 5 years = €15,000 in arrears, plus interest.
• Probation period overflow. Convention collective limits probation; using a longer Code du travail period is invalid.
• Salary below minimum. Salaries below the convention collective minimum trigger arrears claims.
• Ignoring extension. Believing the convention collective is “voluntary” and can be ignored — extension by ministerial order makes it mandatory.
• Confusing convention collective with company agreement. The two operate at different levels; neither replaces the other.

10. The Convention Collective and Mobility

Some conventions collectives include mobility clauses — specifying the geographic radius within which the employer can require the employee to move. Without such a clause in the convention, the employer must obtain the employee’s consent for any geographic change beyond the same “bassin d’emploi” (employment area).

11. Termination — The Convention’s Role

At termination, the convention collective governs:

• The applicable notice period (longer than statutory in many cases).
• Any sectoral severance pay above statutory.
• Any non-compete clause limits (some conventions cap non-compete at 12 months and require minimum compensation — e.g., 33% of average salary).
• Outplacement obligations for collective dismissals in some sectors.

12. Updates to Conventions Collectives

Conventions collectives are renegotiated periodically. Recent significant changes:

• Syntec (IDCC 1486) — major salary scale revision in 2023, periodic minimum salary updates.
• HCR (IDCC 1979) — major rewrite in 2022 with substantial wage increases.
• Métallurgie — comprehensive new convention 2024, replacing the 2002 framework.

The employer must monitor these changes — a salary at €30,000 last year may be below the 2026 minimum for the same classification.

13. The MmowW Scrib🐮 Workflow

Cell #16 (FR Employment) integrates convention collective lookup:

• User enters the employer’s NAF/APE code or convention collective name.
• System identifies the IDCC.
• Pre-populates the contract template with the relevant minimum salary, probation, notice period, leave, and 13ème mois rules.
• Generates a checklist of convention-specific compliance items (mutuelle santé scheme, mobility radius, training obligations).
• Tracks convention updates and prompts the user to refresh on each annual review.

14. The Bigger Picture

The convention collective system is one of the distinctive features of French employment law. It places industry-level negotiated minimums above company-level economics — protecting the employee from being undercut by competitive employers and ensuring sectoral stability.

For founders unfamiliar with the system, the surprise is often the depth of obligations layered on top of the statutory baseline. A French employment contract that simply mirrors the Code du travail is unlikely to be compliant — the convention collective adds 30–60% more substance in most cases.

The MmowW Scrib🐮 workflow exists specifically to surface this layer at the moment the contract is drafted, before non-compliance becomes a wage-arrears claim five years later.
