This Policy Brief is based on empirical data collected through focus groups and foresight exercises organized with representatives of public authorities, social partners and other experts from Austria, Bosnia and Herzegovina, and Slovenia during 2019. It describes the trend of the posting of workers from Bosnia and Herzegovina via Slovenia to Austria and its drivers.  It then discusses why workers from Bosnia and Herzegovina agree to be posted via Slovenia to work in Austria, the challenges they face and the impact it has on the host country. The Brief concludes with recommendations on how the observed problems could be addressed.
