The knowledge workers who form the core of the crew of a modern organization have emerged. They have a unique position in an enterprise, which complicates the incentive system building process and managers’ formal impact on their activities. With a „deep-smarts” status, they adopt the attitudes that restrain or even intentionally hide knowledge flow. Providing support to organizational culture is crucial for motivating knowledge workers to contribute to an organization with their knowledge. This research paper is mainly aimed at identifying knowledge workers’ preferences for organizational culture. The paper focuses on indicating the directions of the development of Polish IT companies’ organizational culture in line with the attitudes of the professionals aiming to stimulate their involvement in the implementation of specific knowledge diffusion subprocesses. The paper is based upon the empirical research conducted on a sample of 105 IT sector knowledge workers in Poland in 2020.
