Right of Alert by CSE: Employees Departing the Company Cannot Invoke It

By DAIRIA Avocats | Employment Law | Case Commentary

On March 18, 2026, the Court of Cassation, Social Chamber, clarified a key condition regarding the admissibility of the right of alert exercised by a member of the CSE (Comité Social et Économique, Social and Economic Committee) in cases of violations of individuals’ rights: the employee concerned must be part of the company’s workforce at the time the court is seized. This ruling clarifies the scope and temporal limits of this protective mechanism.

Facts of the Case

A member of the company’s CSE exercised their right of alert under Article L. 2312-59 of the French Labour Code. This provision allows any CSE member who observes, notably through an employee, a violation of individuals’ rights, their physical and mental health, or individual liberties within the company, which is not justified by the nature of the task to be accomplished nor proportionate to the pursued goal, to immediately bring this to the employer’s attention.

In this case, the CSE representative invoked the right of alert alleging a violation of a specifically identified employee’s rights. The representative subsequently contacted the employer, who failed to conduct an investigation or remedy the situation, prompting the representative to bring the matter before the labor tribunal, which adjudicates in emergency proceedings, in accordance with the procedure set forth by the text.

However, between the time the alert was raised and the time the judge was seized, the concerned employee had left the company. Their employment contract had been terminated for any reason, and they were no longer part of the workforce at the time the court was seized.

Nevertheless, the appellate court held that the right of alert remained admissible, asserting that the violation of rights identified at the time the alert was exercised was sufficient for the judge’s jurisdiction, regardless of the subsequent absence of the employee from the company.

The question submitted to the Court of Cassation was: Can a CSE member exercising the right of alert provided for in Article L. 2312-59 of the Labour Code invoke a violation of the rights of an employee who is no longer part of the company’s workforce at the time the court is seized?

This question raised a fundamental issue regarding the purpose of the right of alert. Does this mechanism aim to sanction a past violation or to stop a current violation? The answer to this question determined the admissibility of the action brought by the CSE representative.

Decision of the Court of Cassation

The Court of Cassation overturned the appellate court’s ruling and established a clear rule. It held that a CSE member exercising the right of alert under Article L. 2312-59 of the Labour Code cannot invoke a violation of the rights of an employee who is no longer part of the company’s workforce at the time the court is seized.

The High Court based its decision on the very purpose of the right of alert. This mechanism is intended to cease an ongoing violation of a worker’s rights. It is a preventive and corrective tool, not a mechanism for sanction or reparation a posteriori. When the employee has left the company, the violation of their rights within the employment relationship has, by definition, ceased.

The Court reminded that the judge seized within the framework of the right of alert rules in emergency proceedings and can order “all measures necessary to cease this violation.” This injunctive power logically implies that the violation is ongoing at the time the judge rules, which necessitates that the employee still be part of the workforce.

This interpretation is consistent with the nature of the right of alert, which is a rapid intervention mechanism designed to protect employees currently on the job, and not a substitute for conventional legal recourse (individual labor actions, union actions, etc.) that remain available to sanction or remedy past infractions.

Article L. 2312-59 of the Labour Code organizes the right of alert of the CSE in case of violations of individuals’ rights. This provision, derived from the previous procedure under Article L. 2313-2 concerning personnel representatives, is one of the most significant prerogatives of the CSE regarding the protection of individual employees’ rights.

The procedure unfolds in several stages. When a CSE member observes a violation of individuals’ rights, they must immediately inform the employer. The employer must promptly conduct an investigation with the CSE member and take necessary measures to remedy the situation. In cases of employer inaction or disagreement regarding the reality of the violation, the employee or CSE member may seize the labor tribunal in emergency proceedings.

The judge can then order all measures required to cease the violation and impose a penalty. This injunctive power is considerable and grants significant practical effectiveness to the right of alert.

Violations Covered by the Right of Alert

The scope of violations covered by Article L. 2312-59 is broad. It includes violations of individuals’ rights (discrimination, moral or sexual harassment, violation of dignity), their physical and mental health (dangerous working conditions, psychosocial risks), and individual liberties (freedom of expression, dress codes, privacy, religious freedom, etc.).

These violations must, however, not be justified by the nature of the task to be accomplished nor proportionate to the pursued goal, which relates to the classical proportionality test of Article L. 1121-1 of the Labour Code.

Previous Jurisprudence on the Conditions of the Right of Alert

The Court of Cassation had previously clarified certain conditions for exercising the right of alert. It had notably ruled that the CSE member must sufficiently identify the alleged violation and the employee concerned (Cass. soc., December 10, 1997, n° 95-42.661). It had also reiterated that the joint investigation phase is a mandatory prerequisite before seizing the judge (Cass. soc., May 15, 2001, n° 99-10.037).

The ruling of March 18, 2026, adds a temporal condition to these requirements: the employee must still be part of the workforce at the time the court is seized. This condition, which had not yet been expressly established by the Court, logically stems from the purpose of the mechanism.

It is important to emphasize that the ruling does not leave an employee who has left the company without recourse. The right of alert is merely one of the available mechanisms. The former employee retains the possibility to individually seize the labor tribunal to have their rights recognized and seek reparation. Unions may also act in substitution in certain cases. Only the specific mechanism of the CSE right of alert is closed when the employee has left the company.

Practical Interest for Employers

Verify Employee Status in the Workforce

The ruling of March 18, 2026, provides employers with a procedural defense in the event of a court being seized in the framework of a right of alert. Before responding on the merits, the employer must systematically verify whether the employee on whose behalf the alert is exercised is still part of the workforce at the time the court is seized.

Points of Caution:

  • Verify the actual date of termination of the concerned employee’s contract;
  • Compare this date with the date the court is seized;
  • If the employee left the company before the court was seized, raise the inadmissibility of the claim based on the ruling of March 18, 2026;
  • Note: an unexecuted notice period does not necessarily equate to departure from the workforce, the employment contract continues until the end of the notice period.

Do Not Neglect the Investigation Phase

While this decision provides a useful procedural argument, it should not lead employers to neglect their obligations during the preliminary investigation phase. When a CSE member exercises their right of alert, the employer must promptly conduct a joint investigation, even if the employee is about to leave the company.

Recommendations:

  • Take every alert seriously and initiate the investigation promptly;
  • Document the entire procedure: date of the alert, identity of the CSE member, nature of the alleged violation, course of the investigation, measures taken;
  • Avoid delaying tactics by waiting for the employee to leave to escape the investigation;
  • Retain evidence related to the employee’s actual departure date.

Anticipate Situations Where Departure Occurs During Alert

In practice, situations where a right of alert is exercised while the employee is in the process of leaving (ongoing notice period, unilateral termination in homologation, fixed-term contract reaching its term) may multiply. Employers must remain vigilant in these cases.

Best Practices:

  • Maintain accurate tracking of ongoing alerts and the contractual status of the concerned employees;
  • Inform the company’s legal counsel as soon as a right of alert is exercised for an employee whose departure is imminent;
  • Avoid accelerating termination procedures to attempt to render the alert inadmissible, which could be construed as fraudulent maneuvering;
  • Remind CSE representatives that the right of alert has a prospective purpose and cannot target situations involving former employees.

Impact on Relations with the CSE

This decision could serve as a constructive dialogue point with staff representatives. It reminds that the right of alert is a tool for protecting employees currently on the job, not a retrospective legal instrument. Employers can encourage CSE representatives to exercise their right of alert early, upon observation of a violation, rather than waiting until an advanced stage where the employee may have left the company.

FAQ – Frequently Asked Questions

Can the right of alert be exercised for an employee in a notice period?

Yes, as long as the employment contract has not been terminated. An employee in a notice period is still part of the company’s workforce. The right of alert remains admissible until the actual end date of the employment contract.

Does the former employee lose all recourse?

No. The ruling only closes the avenue of the CSE right of alert. The former employee retains the possibility to individually seize the labor tribunal to have their rights recognized and obtain reparation. Common statute of limitations applies.

Can the CSE exercise the right of alert for a collective violation?

Article L. 2312-59 of the Labour Code targets violations of individuals’ rights on an individual basis. If the violation affects multiple employees and some are still in the workforce, the right of alert remains admissible for those still employed. Only employees who have left the company must be excluded from the request at the time the court is seized.

Can the employer be sanctioned if no investigation was conducted, even if the employee has since left the company?

The ruling addresses the admissibility of the claim before the judge in the context of the right of alert, not the employer’s liability concerning their safety obligation. The absence of an investigation could be reproached to the employer in the context of another action (individual employee action, union action), independent of the right of alert issue.

When is the condition of presence in the workforce assessed?

The Court of Cassation considers the date the court is seized, i.e., the date the request or summons is filed before the labor tribunal’s judgment office. This is neither the date of the initial alert nor the date of the hearing, but specifically the date the jurisdiction is seized.
