Employees in the German Federal Foreign Service are working worldwide as part of the foreign rotation and are usually sent to different locations every three to four years. International rotation involves both opportunities and risks for employees and their families. This volume examines the effects of these mobility requirements on health, family and partnership. Possible consequences are presented from the point of view of employees, partners and children. It is determined which factors result international rotation becoming a potential burden and which factors protect against potential negative consequences. Among other things, the role of mobility skills will be addressed. The study is based on a comprehensive, standardised, online-based survey among employees of the German Federal Foreign Service, their partners and their children conducted in 2011. Due to the specific mobility requirements, the employees of the Federal Foreign Office and their families are of great significance for research in the field of spatial mobility in the workforce; this applies in particular to expatriates. Recommendations for a successful management of mobility are deduced from the results.
