Can an employer in France dismiss an employee for private Facebook content? Yes, if there is no subterfuge

The French Cour de Cassation has confirmed that an employer could dismiss an employee based on a private Facebook post that breached her confidentiality obligations, because the way it had found out about the post did not involve subterfuge or trickery.  


In April 2014, an employee working in sales in the clothing company Petit Bateau attended a fashion show presenting the future spring-summer 2015 collection. This fashion show was reserved for a restricted audience of Petit Bateau employees.

On being informed by another employee that the employee in question had published a photograph taken during the fashion show on her private Facebook account, the employer decided to dismiss her for serious misconduct, highlighting the breach of her contractual obligation of confidentiality.

To justify the employee’s fault, the employer produced screenshots of the disputed Facebook page.

The case law solution

In a judgment of 30 September 2020 (Cass. soc., 30 September 2020, no. 19-12.058), the Court of Cassation confirmed that the dismissal was valid.

It did not accept the employee’s argument that the employer could not hold against her information relating to her private life which, according to her, had been obtained by an unfair process. The disputed information came from her private Facebook account, which the employer had accessed indirectly (through another employee, himself a Facebook ‘friend’ of the employee).

The right to evidence may justify the production in court of elements that infringe privacy

The Court of Cassation noted that the production of photographs posted on her private Facebook account constitutes an infringement of the employee’s privacy. However, it stated that the right to evidence can justify the production in court of elements that infringe privacy, where two conditions are satisfied:

  • The production of this evidence is indispensable to the exercise of the right to evidence.
  • The infringement is proportionate to the goal pursued.

In this case, the goal was ‘the defence of the employer’s legitimate interest in the confidentiality of its affairs’. It will not escape anyone’s notice that data relating to a future collection, not yet made public, is strategic and sensitive information for the company. This is precisely what justifies the existence of contractual confidentiality clauses (which the employee had signed in the case at trial).


Postings on an employee’s private Facebook account, even if they relate to the employee’s private life, can open the employee up to criticism or disciplinary action by the employer and even justify dismissal for serious misconduct. The solution, set out in relation to Facebook, will be the same regardless of the social network.

The Court of Cassation confirmed that there is no absolute watertight boundary between the employee’s life on social networks and his or her professional life. An employer can use information posted on social networks to sanction an employee.

However, the Court of Cassation reiterated that the method used to gather evidence of the facts observed on social networks is essential. The employer must not have gathered the evidence by subterfuge.

In the case in question, the magistrates noted that, although the disputed photographs had indeed been published on a private Facebook account, they had been spontaneously communicated to the employer by an email from another employee of the company who was a Facebook ‘friend’ of the employee in question and therefore had access to her private Facebook account. Nor was the employer open to criticism for having had a bailiff’s report (constat d’huissier) on the post drawn up: the purpose of this was to prevent any challenge from the employee relating to the identity of the account holder. Moreover, it allowed the evidence to be preserved over time, as content on social networks is volatile.

There was therefore no trickery: this process of obtaining evidence was not considered unfair.

This judgement underlines that is essential for employers to check how evidence is gathered before imposing a penalty on the basis of the facts established, in order to ensure that the procedure involved cannot be described as trickery.

For example:

  • An employer cannot use a ‘friend’s’ Facebook account without his or her knowledge, to spy on an employee’s private account.
  • Similarly, an employer cannot disguise its identity in order to obtain the status of ‘friend’ on an employee’s private Facebook account.
