According to contemporary definitions of employee-driven-innovation, each organization has the potential to create internal innovations. This potential consists of employees who, basing on their knowledge, experience and interactions, create bottom-up innovations in the course of their work. The aim of the article is to highlight the context of employee-driven-innovation in organizations operating in Poland. To achieve this goal, selected definitions were presented in terms of their similarities and differences. The employee-driven-innovation phenomenon was discussed on the basis of the Polish literature review, with a special reference to rationalization phenomenon. Initial considerations on the Polish context were carried out on the basis of individual expert interviews conducted between March 14th and March 30th 2020. The own research focused on two aspects: (1) the degree of organization of the process and (2) features characteristic of organizations operating in Poland. Low level of systemic approach to the process and employee participation in bottom-up innovations was indicated. Further directions of research on the phenomenon were presented, including the aspect of knowledge in organization.
