Abstract

Background: Dissatisfaction with interpersonal relationships in the workplace negatively impacts well-being and work performance. Almost 30 % of people of working age in Finland experience loneliness all or most of the time. Cost-effective methods are needed to improve the social well-being of the general working-age population. This cluster randomized trial aims to investigate whether a mobile application can improve employees' well-being and work-life relationships and reduce their experience of loneliness.
