The Job-Demand Resources theory (Bakker & Demerouti, 2007; 2014.) postulates that, for positive job satisfaction, an adequate balance between the demands of the job and teachers’ personal resources to cope with these demands is needed. A consequence of an imbalance between demands and resources might be teacher attrition. The current study summarizes what is known from five Dutch empirical studies about the frequency and reasons for teachers to leave the profession in the first five years of career. Although it is felt in The Netherlands that the attrition rate is high, compared to some other countries, it appears moderate. We then report on interviews conducted with three early career leavers. Results show that a list of factors may contribute to an imbalance between demands and resources, personal, external as well as organisational. However, it appeared in all cases that a combination of factors, rather than separate factors, were the reason for leaving the profession in The Netherlands.
