French employment law - Dismissal of an employee for violation of its right to freedom of expression: the judge's role (cass soc, September 9th, 26, 25-12.320)

When it is argued before the court that a disciplinary sanction infringes upon an employee's right to freedom of expression, it is the judge's responsibility to balance this right with the employer's right to protect its interests. To this end, the judge must assess the necessity of the measure in light of the objective pursued, its appropriateness, and its proportionality to that objective.

To do so, the judge must consider the content of the offending remarks, the context in which they were made or written, their scope and impact within the company, as well as the negative consequences for the employer. Based on these various criteria, the judge must then determine whether the sanction imposed was necessary and proportionate to the objective pursued.

This is what the Court of Cassation affirmed in a judgment of September 9, 2026 (no. 25-12.320), published in the official bulletin.

The significance of this judgment lies less in a new protection of freedom of expression than in the clarification of the method that lower court judges must now follow.

IV. Analysis.

This judgment of September 9, 2026, is part of the recent evolution of the case law of the Social Chamber concerning the protection of employees' freedom of expression.

The Court of Cassation had already begun, in several judgments rendered in 2026, to strengthen the control exercised over infringements of this freedom.

It no longer limits itself to determining whether the employee's remarks are insulting, defamatory, or excessive: it requires the judge to balance the employee's freedom of expression with the legitimate interests of the employer.

The ruling of September 9, 2026 (no. 25-12.320) clarifies this new method of review, as the Court of Cassation requires judges to assess the necessity, appropriateness, and proportionality of the sanction in relation to the objective pursued.

To carry out this balancing act, judges must consider not only the content of the remarks, but also their context, scope, impact within the company, and any potential negative consequences for the employer.

This requirement is a continuation of the decisions rendered on January 14, 2026 (no. 23-17.946) and April 1, 2026 (no. 24-20.863), which had already established this new framework for analyzing employee freedom of expression.

Thus, the significance of this ruling lies less in providing new protection for freedom of expression than in clarifying the method that lower court judges must now follow. The sharp, ironic, or inappropriate nature of certain remarks is not, in itself, sufficient to constitute misconduct justifying dismissal.

The judge must determine whether the sanction was necessary and proportionate in light of all the circumstances.

This approach therefore leads to assessing the employee's remarks not in isolation, but in the context of the professional situation in which they were made.
