Organizational support on knowledge sharing : a moderated mediation model of job characteristics and organizational citizenship behavior

Purpose: This paper aims to study the effects of perceived organizational support (POS) on employees’ knowledge sharing intention (KSI). More specifically, this study examined whether these effects are moderated by job characteristics (JCs) and are mediated by organizational citizenship behavior (OCB). Design/methodology/approach: Data for 426 employees were collected via an online questionnaire from four IT companies in South Korea. Combined effects in the variable set were analyzed using conditional process analyses (Hayes, 2013). Findings: The results indicate that POS positively affects OCB and KSI, and that JCs moderate the relationship between POS and OCB. Also, the relationship between POS and KSI is mediated by OCB, and the hypothesized moderated mediation model is confirmed. Originality/value: This study is novel in empirically establishing how employees’ KSI is affected by POS as an integrative construct bringing together JCs and OCB. This paper intends to fill a methodological gap and nurture future research by adopting conditional process analyses assessing whether JCs moderate the relationship between POS and OCB and mediate the effects of OCB on KSI.
