Early childhood teachers' work satisfaction is an essential prerequisite for their work attainments and quality work outcomes. At the same time, besides their professional well-being, their personal well-being is of utmost importance, which raises the question about the nature of their relatedness. Therefore, this study was aimed to explore the personal and professional well-being among Croatian early childhood teachers. A total of 179 early childhood teachers from the Kindergarten “Rijeka” have participated in this research. Results showed that early education teachers were moderately satisfied with their work. Similarly, results about their personal well-being demonstrated moderate to high levels of optimism, positive emotions, flow, and life satisfaction. Correlation analyses revealed significant positive relationship between high levels of all personal well-being dimensions and high level of work satisfaction. Additionally, it was determined that older and highly experienced early childhood teachers are significantly less satisfied with work and less optimistic.
