With the pervasiveness of information and communication technologies (ICTs) in organisations, employees continuously interact both online and offline. This continuous interaction leads to the construction of norms and obligations around the usage of technology, which can also result in negative impacts on employees’ health, for example, technostress. Previous Information Systems (IS) research on technostress has focused on psychological or neurophysiological quantitative research on the use of ICT and its effects. To our knowledge, there are no technostress studies that make use of the role of obligation, which in our view is a crucial lens, as it shifts the technostress debate to showing how the felt obligations constructed around the use of ICTs can lead to technostress. To further explore how technostress arises, we use the analytical concept of obligation from the discipline Sociology of Emotions. Our data comes from an exploratory case study in a Danish private company. We find that employees take on themselves the ideals of ICTs being seamless, and when ICTs do not live up to their expectations, they experience shame and guilt. To avoid such feelings, they construct obligations that lead to technostress. We contribute to IS research on technostress by showing how obligation contributes to technostress.
