What happened, and why it matters

A Milan area startup built a plug in for Slack and Microsoft Teams that read the emotional content of workplace messages and reported inferred stress levels to employers. The Italian authority issued a formal warning under provvedimento no. 342 of 14 May 2026 rather than a fine, putting the company on notice that shipping the product as designed would breach both the GDPR and the AI Act. The AI Act citation is what makes this the most significant record on the tracker. Article 5(1)(f) prohibits placing on the market, putting into service or using AI systems to infer the emotions of a natural person in the workplace, outside narrow medical and safety exceptions, and that prohibition has applied since 2 February 2025. This is the first published European decision to invoke it. It is a warning, not a penalty, and the Garante is a data protection authority rather than a designated market surveillance authority under the AI Act, so the record is properly read as a data protection authority applying the AI Act as context to a GDPR assessment. It is not a fine under Article 99 and it does not make the count of AI Act fines anything other than zero. It is, however, the moment the prohibition stopped being theoretical.
