Friendship Knowledge Sharing, Interpersonal Justice and Sustainability Performance: Scale Development and Validation

Abstract

Purposes: This present study purposes to develop a new construct of friendship knowledge sharing (FKS) as a new concept of knowledge sharing behavior. Subsequently, this research also investigates the effect of FKS on employee’s sustainable performance through interpersonal justice as a mediating variable.   Theoretical Framework: This study synthesizing a new construct of FKS by relying on the lens of social capital theory and knowledge sharing. In addition, based on social exchange theory, this study linking FKS to sustainable performance via interpersonal justice. This study assumes that FKS can improve perception of interpersonal justice that finally shares a positive effect on employee’s sustainability performance.   Design/ methodology/ approach: This study divided in to two stages. In the study 1, deductive method in scale development involves item generation based on an extensive literature review and pre-existing scales. Subsequently, this study encompassed scale refinement to assess exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) of the scale, with the participation of 233 public school teachers in Indonesia. Study 2 focuses on the test of the relationship between FKS on the employee sustainable performance, while assessing interpersonal justice as mediating variable. To evaluate the research model, Smart PLS 3 were employed to examine the connection between latent variables.   Findings: The results show that friendship knowledge sharing can be comprehensively measured from five dimensions: voluntary, informal, socio-emotional support, communal norms, and trust. This article contributes to the knowledge sharing literature by providing an original view on developing the friendship knowledge sharing scale. This research also found that all FKS dimensions has a significant effect on employee’s sustainability performance. According to effect analysis, this research conclude that interpersonal justice mediates the connection between FKS and employee’s sustainability performance. However, this study found the insignificant mediation effect of interpersonal justice on the informality-sustainability performance. Implications: This article contributes to the knowledge sharing literature by providing an original view on developing the friendship knowledge sharing scale. This research also offers valuable insights into management to create a more collaborative and supportive environment among employee, ultimately enhancing perception of interpersonal justice and in turn nurturing sustainability performance.
