Digital trade union campaigning: No entitlement to email addresses or internal platform access
In its judgment of 28 January 2025 (1 AZR 33/24), the German Federal Labour Court (Bundesarbeitsgericht, BAG) decided on the question of whether the tariff-responsible trade union can request the individual employer to use the company's digital communication tools (such as company email addresses, internal platforms or intranet links) for campaigning and information purposes – with negative answer.
Facts
- The plaintiff is the trade union responsible for collective bargaining for the defendant – the parent company of an internationally active group of companies. The trade union wanted to adapt its membership recruitment and information work to the changed working conditions and communication habits and to rely more heavily on digital channels.
- In a large enterprise belonging to the defendant with approximately 5,400 employees, the plaintiff demanded digital access rights to company communication tools, as many employees work remotely and are not regularly on site to distribute campaigning and information digitally.
- Specifically, the plaintiff demanded:
o Disclosure of all work email addresses of employees working at the company
o Establishment of an automated email distribution list
o Access to the group-wide communication platform ‘Viva Engage’ (formerly Yammer) as an ‘internal user’
o Permanent link to her website on the intranet homepage
- The defendant rejected the union's demands, citing data protection, disruption to business operations and interference with its entrepreneurial freedom, among other things.
Reasons for the decision
- No legal basis: Neither Art. 9 (3) of the German Constitution (Grundgesetz, GG, freedom of association) nor ordinary statutory provisions (Section 2(2) of the German Works Constitution Act (Betriebsverfassungsgesetz, BetrVG), Section 78 s. 2 BetrVG) justify a claim to the requested digital access to the employer. An analogous application of the intranet linking obligation provided for in the Federal Personnel Representation Act (Section 9 (3) sentence 2 of the German Federal Personnel Act (Bundespersonalgesetz, BPersVG) is not applicable in works constitution law.
- Freedom of association protects digital campaigning – but not by all means: Freedom of association also includes the right of a trade union to recruit members and inform employees – including via digital communication channels. However, this right is not unlimited: it must be balanced against the employer's fundamental rights, such as property rights (Art. 14 GG) and freedom of enterprise (Art. 12 (1), 2 (1) GG).
- The release of all work email addresses would cause a considerable amount of ongoing organisational effort, as the lists would have to be continuously updated. In addition, it would disclose the personal data of all employees and interfere with their data protection interests. Employees should not be added to a mailing list without their consent; rather, they can voluntarily provide their addresses. Protection against unsolicited electronic campaigning therefore outweighs the trade union's campaigning interests.
- Access to ‘Viva Engage’ as an ‘internal user’ would give the trade union far-reaching insights into internal company and employee data – including posts, files, profiles, group memberships and communication histories. This deep insight goes far beyond what is necessary for campaigning purposes and is therefore disproportionate.
- A permanent link on the intranet homepage would give the trade union a permanent digital presence on the company's website. However, the company's freedom of design includes the decision as to which content is prominently displayed there. Furthermore, as there is already a link via the general works council's page, there is no need for this.
Consequences for practice
The BAG's decision makes it clear that there is no general digital access right for trade unions. Employers are not obliged to disclose work email addresses, grant access to internal platforms or set up permanent intranet links.
For trade union activities, this means that traditional means of access – in particular physical access to the workplace – continue to be considered sufficient. Trade unions must base digital contacts on data voluntarily provided by employees or use their own channels outside the employer's infrastructure.
Employers can protect their digital communication systems from external use through clear internal regulations or works agreements without violating freedom of association. At the same time, voluntary solutions – such as temporary intranet notices or agreed digital formats – can be considered in individual cases to promote constructive dialogue.
