Purpose: The main aim of the article is to evaluate and analyze the role, participation and work motivation of women and men in the science sector in Poland. Design/Approach/Methodology: Two research themes are presented during the research. The first one concerns determination of the share and role of women in the academic sector in Poland in 2008-2018 and it is a macro perspective. The second research theme includes motivation factors in research institutes in the light of the surveys' results. Findings: According to the research results the place and role of women in obtaining higher degrees in academic career in Poland (post-doctoral degree and professor's title) was still significantly lower than the place and role of men. Additionally, there were still some inequalities in using motivating factors between men and women. Practical Implications: Sustainable development will not be possible without gender equality and the recognition of women's work. It will also not be possible to achieve the full benefits of this development that serve present and future generations. Therefore, the elimination of diagnosed symptoms of discrimination may contribute to increasing the innovation of scientific research and, as a result, to improving the quality of life in modern world. Originality/Value: Research in this area has not yet been more widely conducted and described in the literature on the subject, therefore its results are a valuable source of information on gender equality in the Polish academic sector.
