Purpose - The paper aims to serve as a reminder of the fact that informal organizational culture remains the foundation of healthy and productive work environments. Design/methodology/approach - First, Elton Mayo's classic contribution to organization studies is brought to the reader's attention. Mayo was among the first scholars to assess empirically the importance of teamworking. Second, more recent studies are reviewed. The review highlights the value of collaborative problem solving among knowledge workers, i.e. experts whose job requires a high level of formal education, symbolic skills and the use of information technology (IT) in supporting their decision-making process. Findings - The review indicates that, contrary to an all-too-common belief, IT bears little direct relevance to knowledge workers' performance. However, if used properly, it can indirectly contribute to creating more space for interpersonal interaction by eliminating routine communication. In its essence, modern IT simply continues the long trend of the automation and mechanization of work. Originality/value - The review suggests that existing knowledge about human behavior is far less than adequately applied. Therefore, the paper encourages managers to pay less attention to the latest technology and more attention to human relations.
