The results obtained in the course of the study indicate that there is not only a strong correlaton between trust and collaboratve culture but both of them have a strong infuence on tacit knowledge sharing. The main managerial implicaton of the study is the importance of stmulatng the growth of both collaboratve culture and trust. receiving a strong synergy efect will make it possible to leverage tacit knowledge sharing as an agent contributng to a company’s performance.
