In recent years, knowledge management has been utilized as an essential strategy to foster the creation of organizational intellectual capital. Organizational intellectual capital can be derived both individually and collectively in the process to create, store, share, acquire, and apply personal and organizational knowledge. However, some organizations only focus on the development of public good, despite the concerns arising from individuals' self-interest or possible risks. The different concern of individual and collective perspectives toward knowledge management inevitably leads to ethical conflicts (...) and ethical culture in the organization (Jarvenpaa et al., J Manage Inf Syst 14(4): 29-64, 1998; Ruppel and Harrington, IEEE Trans Prof Commun 44(l): 37-52, 2000). The purpose of this study is to examine the ethical climate within the organization and its possible influence on members' evaluation, satisfaction, engagement, and job performance with respect to knowledge management practice. The research results reveal that several types of organizational ethical climate coexist in the organization and have different degrees of influence on employees' attitude as well as participation in knowledge management activities. In this article, we argue the importance of organizational ethical climate and highlight the implications of such a climate for facilitating knowledge management. (shrink)
