An occupational health management system was initiated at 11 departments under the German Ministry of Defense (MoD) at the beginning of 2015. The departments were characterized by the heterogeneity of employees and the tasks of the departments. The aim of this pilot phase was to get experience and knowledge for implementation of this system in other departments. At the beginning of the pilot phase, an employee attitude survey was conducted to examine the situation.The survey included all 9,267 employees of the eleven departments. A combination of a web-based online survey and a paper-pencil survey was used.In total, 2,076 (22.4%) of all employees took part in the survey. There were significant difference between the departments in all topics assessed ("leadership behaviour/social issues", "work habits", "job design", "work equipment", "environment conditions", "mental health", "stress", "diet", "exercise", "job responsibility") but not in "health behavior".This study shows clearly that a department-based analysis is necessary for a goal-oriented meaningful occupational health management system, especially if only limited resources are available.
