The technological potential to separate work from the workplace is constantly increasing. Mobile devices with mobile internet access and remote access to firms' internal networks and data allow to work anywhere at any time, i.e. Ubiquitous Working (UW). In April 2014, ZEW started the project "Ubiquitous Working: Challenges and Prospects of the Interconnected Working Environment“, which is supported by the Leibniz Association. For the next three years, an interdisciplinary network of scholars engaged in exploring the chances and challenges will be arising from UW by using theory-based empirical research. For this purpose, the project makes use of rich data on both employees and employers in order to examine the diverse dimensions of UW that are relevant from the perspective of the disciplines involved in the project – economics, work psychology, media psychology, occupational medicine, and sociology. The projects objective is to bring together scholars of these disciplines in a closely collaborating network of institutions and scholars in order to gain deeper insights into the phenomenon of UW.
