Abstract
The aim of the article is to determine the relatedness between the quality of interpersonal relationships, measured by the level of their positivity, with knowledge sharing among members of the top management teams (TMT). The analyses primarily concerned the relatedness between interpersonal relationships and a) the declared individual tendency to share knowledge, b) the motives of knowledge sharing among members of the surveyed teams, c) the forms of knowledge sharing. The empirical basis of the article is a CATI research on a sample of 123 managers who are members of decision-making teams in the furniture industry in Poland. The results obtained suggest that knowledge sharing within management teams is related to the level of positive interpersonal relationships of their members. These relationships strengthen the intrinsic motivation to share knowledge, reducing the importance of extrinsic motivators, as well as foster informal and direct forms of knowledge sharing, reducing the importance of institutionalized forms.
