In today’s working world communication via information and communication technologies (ICTs) such as email, phone calls and messenger services plays an increasingly important role. Communication overload (CO), arising from the social load of too much communication via ICTs, is a relevant modern job stressor linked to exhaustion and reduced well-being. This stressor may in turn reduce employees' psychological detachment during non-work time, thereby impairing recovery and potentially explaining part of CO's negative outcomes. The aim of this study therefore is to investigate the potential link between CO at work and psychological detachment during non-work time. Segmentation preference and boundary control will be included as possible moderators of this relationship.
