A policy circulated by email informs. On its own, it does not allow you to sanction a breach.
Inform employees, in all cases. Whatever the headcount, no information concerning an employee personally may be collected by a system they have not been told about beforehand (Article L1222-4 of the French Labour Code). If you monitor the use of tools, say so in the policy.
Consult the CSE. In companies with at least 50 employees, the works council (comité social et économique, CSE) is informed and consulted on the introduction of new technologies (Article L2312-8). Consult it before AI tools are deployed, not afterwards. Below this threshold, employees must still be informed beforehand.
Attach the policy to the internal regulations. Internal regulations (règlement intérieur) are mandatory from 50 employees (Article L1311-2). A document containing general and permanent obligations may be treated as an addition to the internal regulations, and follow the same procedure (Article L1321-5). That procedure is as follows (Article L1321-4):
- the opinion of the CSE;
- communication to the labour inspector, together with that opinion;
- entry into force at least one month after the rules have been made known to employees.
Since the law of 26 May 2026, filing with the registry of the employment tribunal (conseil de prud'hommes) is no longer a condition for entry into force.
