German Court Blocks Four-Day Office Mandate as EU AI Act Penalties and New Surveillance Tools Converge

A recent ruling by the Düsseldorf Labour Court has pushed back against employers' efforts to enforce rigid in-office attendance. The court declared invalid an order requiring an IT employee to work from the office four days a week (Case No. 3 Ca 6587/25). The employer failed to demonstrate that physical presence would improve workflow. However, the court did not grant the employee a general right to a fixed home-office quota.
The decision lands at a moment when workplace surveillance is under fresh scrutiny. Starting in June 2026, Microsoft will roll out a feature called "Workplace Check-in" within its Teams platform. The tool uses WLAN signals and IP addresses to detect whether employees are at the office, then sends that data directly to Microsoft Places. By default the function is switched off; IT administrators must activate it. In Germany, that activation triggers co-determination rights under Section 87 of the Works Constitution Act (Betriebsverfassungsgesetz). Employees must also actively consent to location sharing. Critics have labelled the system as outright monitoring software and warn that it could ratchet up pressure on staff.
Courts are simultaneously tightening the boundaries for digital oversight. Cologne-based employment lawyer Volker Görzel explains that the legality of checking messages on services like Teams or Slack depends on whether private use is permitted. If a company strictly prohibits private use, the employer may monitor. Violations can lead to warnings or dismissal. When private use is allowed, monitoring is only permissible if there is a concrete suspicion of a criminal act or a serious breach of duty. Any check must be proportionate and transparent—conducted in the presence of the employee and the data protection officer.
Data-handling failures within employee representation bodies have also drawn legal consequences. In March 2025, the Hesse State Labour Court confirmed the removal of a works council chairperson who had forwarded sensitive personnel data to private email addresses. Experts stress that data should only be processed on company-provided devices.
Beyond these domestic rulings, new European regulations are adding compliance pressure. Germany already missed the June 7, 2026 deadline for transposing the EU Pay Transparency Directive, which expands information rights and reporting duties aimed at eliminating pay discrimination. Violations carry a reversal of the burden of proof and other sanctions.
More urgently, from August 2, 2026, obligations under the EU AI Act for high-risk artificial intelligence systems take effect. Fines can reach up to €35 million. The IG Metall union is calling for clear rules governing the use of AI in the workplace. A PwC Global AI Jobs Barometer points to a potential upside: companies that pursue a combined human–AI strategy report significantly stronger workforce growth and productivity gains than those that simply automate tasks.
