**5. Conclusions**

The implementation of health-related measures among companies of one county in southwestern Germany is heterogeneous. There are major shortcomings regarding compliance with legal requirements, as well as specifically in the domain of occupational health and safety measures. Although there is a positive correlation between implementation and satisfaction, surprisingly many companies are satisfied despite a comparably poor implementation of single measures of workplace health management. These conditions—even in a country where occupational health and safety as well as reintegration management for employees are legally required—must be taken into account before planning interventions to improve workers' health through a comprehensive approach.

A.H., A.S., and M.A.R. developed the study design; A.H., A.S., and M.A.R. developed the questionnaire; and A.S. performed the pre-test. A.H., A.S., and M.A.R. planned the data collection, wrote the study protocol, and performed the survey. A.H. and A.E. performed the statistical analysis and received valuable advice from A.S. and M.A.R. All of the authors read and approved the final manuscript.

**Funding:** The survey was financed by the institute's own resources. The work of the Institute of Occupational and Social Medicine and Health Services Research Tübingen is supported by an unrestricted grant of the Employers' Association of the Metal and Electric Industry Baden-Württemberg (Südwestmetall).
