摘要:Tacit knowledge sharing is an essential intellectual capital for frontline employees in hotel enterprises. While the relationship of knowledge sharing with team culture (TC) and innovative work behavior (IWB) was investigated in the extant literature, little is known about the extent to which tacit knowledge sharing affects TC and IWB. In this regard, the purpose of this study is to investigate the role of tacit knowledge sharing in the relationship between TC and IWB. For this purpose, data were gathered from 360 department managers of Turkish 4–5 star hotels. The results were analyzed utilizing Smart PLS 3 using bootstrapping to determine the level of significance of the relationships between tacit knowledge sharing, TC and IWB. The results show statistically significant relationships between tacit knowledge sharing, TC and IWB. Moreover, tacit knowledge sharing has a mediating role in the relationship between team culture and innovative work behavior.
