The productivity and competitiveness of a company depend, among other factors, on the health of its employees. Occupational Health Management (BGM) can reduce costs and increase work efficiency over time by decreasing illness-related absences. The specification DIN SPEC 91020:2012-07 supports the harmonization of an organization's Occupational Health Management system with the requirements of other management systems, such as ISO 9001, thereby enabling the integration of all management systems into a cohesive whole. The authors provide commentary on the requirements of DIN SPEC 91020 section by section, incorporating relevant legal texts, necessary documents, and records. Guiding questions, key figures, and additional notes complement the discussion.
