Cooperation among employees in educational institutions such as kindergartens is an indispensable component of the quality of the institution itself. Cooperation is determined by the quality of the relationship between the educator (in this case preschool teacher) and the professional team. The level of quality in this relationship enables both sides to provide research and change of both educational practice and one's own actions. It is inevitable to see a connection of cooperation of educators and the professional team and its affect on the satisfaction with the educational work. Satisfaction in this case is the attitude that educators have when their needs and interests are met, when a high level of quality in interaction with colleagues is reached and when they are satisfied with the working conditions and the awards they receive for that work. For this reason, this paper examines the educator's experience of cooperation with the professional team as well as satisfaction with the educational work and whether there is a connection between these areas. The questionnaire surveyed 147 educators of the City of Zagreb and the results showed that there is a statistically significant relationship between the level of cooperation between educators and the professional team and their perception of satisfaction with educational work, ie better cooperation between educators and the professional team initiates better satisfaction with educational work.
