Introducing AI at work: employee consultation rules in the EU
Introducing AI at work often requires employee consultation before you decide, not after. EU law sets a baseline: employers above a size threshold must inform and consult employee representatives on decisions likely to change work organization substantially.
National rules go further: German works councils, French CSEs, Swedish unions and the Finnish Co-operation Act each set their own triggers, compared in the table below.
A common assumption is that a pilot needs no consultation. Not so in France: a court has treated a pilot on live work as deployment, so the consultation had to come first.
Status as of October 13, 2026. Not legal advice: the rules depend on your company size, collective agreements and the exact tool, so check your case with a labor law specialist.
The EU baseline: the Information and Consultation Directive
Directive 2002/14/EC sets minimum rules for informing and consulting employees. Each Member State chose whether it covers undertakings with at least 50 employees or establishments with at least 20. Article 4(2)(c) covers "decisions likely to lead to substantial changes in work organisation or in contractual relations", and Article 4(4) requires consultation "with a view to reaching an agreement".
Rolling out an AI assistant to a whole department can be such a change; a single team trying a writing tool usually is not. Your actual duties come from national law in each country where you employ people.
The EU AI Act adds one duty: employers must inform workers' representatives and the affected workers before using a high-risk AI system at the workplace (Article 26(7), Regulation (EU) 2024/1689). High-risk uses include AI for recruitment, promotion, task allocation and performance monitoring. After the Digital Omnibus, these Annex III rules apply from December 2, 2027.
Employee consultation rules by country
Germany: works council co-determination
The works council co-determines the introduction and use of technical devices designed to monitor employees' behavior or performance (§ 87(1) no. 6 of the Works Constitution Act, BetrVG). Without its agreement, such a tool needs a conciliation board decision (§ 87(2)).
Two further rules name AI. You must inform the works council in good time about planned work procedures, including AI, and discuss their effects (§ 90(1) no. 3). If it has to assess AI, bringing in an expert is deemed necessary (§ 80(3)).
The Hamburg ChatGPT case. On January 16, 2024 (24 BVGa 1/24), the Hamburg Labor Court rejected a group works council's request to stop staff using ChatGPT and similar tools. Employees used the tools in a browser, with their own accounts where needed, under guidelines on the intranet. The court found no co-determination right: the guidelines concerned how work is done, and the employer got no usage data, so it monitored no one (Gleiss Lutz summary).
The decision is narrow, from interim proceedings at first instance, and could go differently where the employer provides company accounts and sees usage data (CMS). Enterprise tools such as Microsoft Copilot run on company accounts with usage reporting for admins, so plan for works council involvement.
France: consult the CSE before deployment, including pilots
In companies with 50 or more employees, you must inform and consult the social and economic committee (CSE) before deciding on new technologies or significant changes to working conditions (Labor Code, Article L2312-8).
On February 14, 2025, the Nanterre Judicial Court (interim order no. 24/01457) suspended an employer's rollout of several AI applications until the CSE consultation was complete. The employer called it a pilot. The court disagreed: once employees used the tools, it was a first implementation, and deploying before the CSE's opinion was manifestly unlawful (CMS France commentary).
Sweden: MBL § 11 and § 19
The Co-determination Act (MBL, SFS 1976:580) has no size threshold:
- § 11: If you are bound by a collective agreement, you must, on your own initiative, negotiate with the union before deciding on a major change to your operations or to the working or employment conditions of its members.
- § 19: You must keep that union continuously informed about how the business develops and about your personnel policy.
- § 13: If the change particularly affects members of another union, you may have to negotiate with that union too.
Whether an AI rollout is a "major change" depends on scope: a company-wide assistant that changes how case handlers work is a stronger case than a tool for a few specialists.
Finland: the Co-operation Act
Since July 1, 2025, the Co-operation Act (1333/2021) has applied in full only to employers with at least 50 employees. Amendment 252/2025 raised the threshold from 20 (Finnish Government), so check that any English translation reflects it.
For employers with 50 or more employees:
- Ongoing dialogue (§ 8) covers workplace rules and practices and the competence needs of personnel.
- The development plan (§ 9) sets out competence measures and considers the impact of technological development.
- Technical monitoring and email (§ 12), including the purpose and methods of monitoring, belong in the dialogue.
- Change negotiations (§ 16) are required when new technology causes significant changes in duties, working methods or work arrangements.
Employers with 20–49 employees have lighter duties. They set up their own practices for regular dialogue (§ 7a) and handle § 12 matters, such as technical monitoring, there. The § 9 development plan and § 16 change negotiations over new technology do not apply.

Tip: The Aigen Campus AI policy builder includes a section on the Finnish Co-operation Act and records which policy version each employee acknowledged. The draft still needs your review.
Steps for any EU employer introducing AI
- List what you plan to introduce. For each tool, note who will use it, what changes in their work, what data it processes, and whether you can see usage or output data.
- Find the right representatives in each country: works council, CSE, union or personnel representative. Check collective agreements for extra rules.
- Inform before you decide, and before any real-work pilot.
- Share enough to discuss: purpose, tools, data flows, monitoring capability, expected changes to tasks, and planned training.
- Consult with a view to agreement and keep minutes of proposals, concerns and what you changed.
- Check data protection in parallel. If AI processes employee data or enables monitoring, assess whether you need a data protection impact assessment (GDPR Article 35).
- Publish an AI policy and train staff. This also supports AI literacy under Article 4 of the AI Act: see Article 4 after the Digital Omnibus and the Commission's AI literacy Q&A.
- Review when the tool changes. As the Hamburg case shows, moving from private to company accounts or adding a usage dashboard can change the legal picture.
Representatives also ask how people will learn to use the tool well and safely. In the Aigen Campus course, module 3 covers AI in everyday work by role, and module 5 covers keeping data safe.
Frequently asked questions
Do we need works council approval to use ChatGPT in Germany?
It depends on the setup. In the Hamburg case, browser use with private accounts and no employer access to data did not trigger co-determination. Company accounts with visible usage data are more likely to fall under § 87(1) no. 6 BetrVG.
Does a pilot of an AI tool need employee consultation?
In France, a pilot in which employees use the tool in real work can count as deployment and require prior CSE consultation. Elsewhere, informing representatives before a pilot starts is the safer course.
Do small companies need to consult employees about AI?
It varies. The Finnish Co-operation Act applies in lighter form from 20 employees, French CSE consultation from 50, and the Swedish MBL has no threshold. German rules apply wherever a works council exists.
Does the EU AI Act require employee consultation?
Only for high-risk AI: from December 2, 2027, employers must inform workers' representatives and affected workers before using such a system at the workplace. Broader consultation duties come from labor law.
Get started
Representatives often ask first to see your AI policy. The Aigen Campus AI policy builder drafts one after a questionnaire of about 10 minutes, covering data classes, approved tools and acknowledgements, and it is free to use and publish. Review the draft with your representatives before rolling out new tools.
