The topic of this Master's Thesis is the examination of the relationship between working conditions, job satisfaction, and burnout syndrome in early childhood and preschool educators. As a part of this Master's Thesis, a survey was conducted in March and April 2020 on a sample of 207 early childhood and preschool educators from various parts of Croatia. The instruments that were used for this research include the following: the Oldenburg Burnout Inventory – OLBI (Demereuti et al., 2003), the Teaching Satisfaction Scale (Ho and Au, 2006), and the Scale for Assessing Stress in Kindergarten Teacher's Work (Živčić-Bećirević and Smojver-Ažić, 2005). The results obtained by this research point to the fact that three out of four subscales of stress sources (personal relationships, child behaviour problems, working conditions) are significantly negatively associated with higher job satisfaction, while subscale relationship with parents is not significantly associated with job satisfaction. Furthermore, all four categories of stress sources are significantly associated with higher burnout rates in educators. Also, it was found that there was no statistically significant association between work experience and burnout rates in educators. However, a positive association was found between work experience and job satisfaction. By examining the relationship between burnout rates and the size of places where the research was conducted, a statistically positive association was found. On the contrary, no association was found in the relationship between job satisfaction and the size of places where the research was conducted. The research also sought to examine the differences in job satisfaction and burnout rates among educators working in different types of facilities. However, the results showed no statistically significant differences between central and local facilities.
