The document discusses the psychological contract of knowledge sharing in technological organizations. It argues that knowledge sharing is a natural act for both animals and humans, as sharing knowledge provides collective benefits. However, four levels of restraining forces can inhibit knowledge sharing in organizations: social, technological, organizational, and personal. At the personal level, barriers include ignorance of one's own knowledge and lack of reflection. To overcome these barriers and encourage more natural knowledge sharing, the document recommends clarifying mutual obligations, ownership of knowledge, and learning duties in the psychological contract between employees and the organization.
