The popular standard commentary on labor law offers a high-quality comprehensive commentary on the extensive field of labor law in a single volume. For quick access, it is organized alphabetically and now includes commentaries on more than 50 laws (partly in excerpts), including relevant provisions from social security and tax law, as well as commentary on European labor law. In the new edition, the Occupational Safety and Health Act (ArbSchG) is addressed for the first time in excerpts. Overall, the commentaries are based on the legal status as of January 1, 2026, meaning that all legislative changes since the publication of the previous edition have been carefully incorporated, including the Fourth Bureaucracy Relief Act, the Second Company Pension Strengthening Act, laws for further digitization of the judiciary, promoting the use of video conferencing technology in specialized jurisdictions, expanding electronic communication with the courts, and introducing electronic files in the judiciary, as well as the Vocational Training Validation and Digitization Act, the Maternity Protection Adjustment Act, the Future Financing Act, and much more. The extensive relevant case law from the European Court of Justice, the Federal Labor Court, and the lower courts has also been meticulously evaluated and incorporated—always cited with date and file number for easier tracking and optimal linking in case of database use. The focus of the experienced experts from academia and judicial as well as legal practice is on providing problem-oriented information to the reader, including questions of legally secure design. Thanks to the concise presentation and the broad experience of the authors, the work enables quick and comprehensive legal advice for the diverse questions of labor law practice.
