The influence of organisational commitment on employees' work-related use of online social networks The mediating role of constructive voice

Purpose Although online social networks (SNs) (e.g. Facebook, LinkedIn and Instagram) have been used by employees for various work- or non-work-related motives, there has been lack of research on the use of such networks in the workplace. The purpose of this paper is to draw on commitment theory and the tricomponent attitude model to explain the role organisational commitment plays in predicting the work-related use of online SNs and the mediating role a constructive employee voice may have in this relationship. Design/methodology/approach The research was conducted among the employees of seven different companies within seven different industries. The validity of the measures and structural models was evaluated using partial least squares structural equation modelling (PLS-SEM). Findings The results indicated that organisational commitment promotes employees' work-related use of online SNs directly and also indirectly via the mediating role of a constructive voice. Originality/value This study is among the few studies which have used the tricomponent attitude model to investigate employees' behaviour in the workplace, in particular work-related use of online SNs. In terms of theory, this study contributes to expanding the boundaries of knowledge as SNs are considered a challenge in contemporary organisations. Organisations can convert this challenge from a potential threat to an actual opportunity by reinforcing "organisational commitment".
