Employment law

Internal rules (règlement intérieur)

10 September 2026

The company's internal law, but a tightly framed power: limited content, mandatory procedure, capped sanctions.

The internal rules are the document by which an employer sets the rules of company life. They are often described as the establishment's "internal law", and the image holds on one condition: like any law, they exist only if the adoption procedure was followed.

This is the point practice most often neglects. Rules posted but not approved by the labour inspector, or approved but applied too early, are not enforceable against employees. Content matters; procedure determines existence.

1. Who must have them?

Internal rules are compulsory in every industrial, commercial or agricultural undertaking employing at least ten salaried workers.

Below that threshold, an employer may adopt them voluntarily, but must then follow the same procedure. An internal document titled "service note" or "charter" that in fact lays down disciplinary rules does not escape the internal-rules regime merely because of its title. Labour Code, Article L.62 (French).

2. What may they contain, and what may they not?

The content is exhaustively defined. Internal rules are devoted exclusively to four areas:

AreaWhat it covers
Technical organisation of workHours, entry and exit, exceptional arrangements, use of premises and equipment
DisciplineGeneral and permanent rules, the scale of applicable sanctions
Hygiene and safetyRequirements applicable in the establishment, protective equipment, procedures to follow
Salary payment arrangementsDate, place and form of payment, in accordance with the law

Anything outside these four areas has no place in internal rules. In practice, the most frequent and most questionable additions are:

Frequently encountered clauseWhy it is irregular
Setting or changing paySalary belongs to the contract and the collective agreement, not the internal rules
Fines or deductions for breachesFines are formally prohibited
Distinctions based on sex, family situation, political or religious beliefsA discriminatory provision has no effect
Waiver of a statutory or contractual rightInternal rules cannot reduce an acquired right

Labour Code, Articles L.64 and L.69 (French).

3. How do they become binding?

The procedure has four steps, each with its own deadline. It is what turns a draft into an enforceable norm.

StepWhat to doDeadline
1. ConsultationSend the draft to the staff delegates, or failing that to the staff representativesThey have 15 days to submit observations
2. TransmissionSend the draft in two copies to the labour inspector, with the delegates' written observations and, where applicable, written reasons for those not retained-
3. ApprovalThe labour inspector reviews the draft: approves it, or requires changesOne month
4. Entry into forceThe rules take effect20 days after approval, the inspector's date and stamp being conclusive

Two classic mistakes. Sending the draft without the delegates' observations: the file is incomplete. And applying the rules from the date of approval: the twenty days must elapse first. A sanction imposed during that period rests on a text not yet in force. Labour Code, Articles L.65, L.66 and L.68 (French).

4. Posting

The internal rules must be posted at hiring points and at the workplace, in an easily accessible position and in conditions that keep them legible.

This is not decorative: posting is what makes the rules knowable to everyone. A properly approved text kept in an office supports poorly the argument that the employee ought to have known it. Labour Code, Article L.67 (French).

5. What sanctions may the rules provide for?

The rules set the scale of sanctions applicable in the company. Those commonly used run from lightest to most serious:

  • the warning;
  • the reprimand;
  • temporary lay-off, which suspends the contract and may not exceed eight days;
  • termination of the contract, where the facts justify it.

Two absolute limits frame this power. Fines are prohibited: the employer may impose no pecuniary sanction. And no deduction may be made from remuneration beyond those the law provides : tax withholdings, social contributions, and lawful assignments or garnishments. A financial penalty disguised as a deduction is still a fine. Labour Code, Articles L.34, L.69 and L.121 (French).

6. What the rules cannot do

Three limits are worth retaining, because they recur in drafts submitted to the inspectorate:

  • They create no right against the employee. Internal rules may neither reduce a statutory or contractual advantage nor introduce an obligation contrary to law.
  • They do not replace the contract. The position, pay and place of work belong to the individual contract; changing them through internal rules has no effect.
  • They cannot be amended unilaterally. Any amendment follows the same procedure as adoption: consultation, transmission, approval, twenty-day period.
