Human Resources researchers have studied extensively the topic of job satisfaction, given the possible consequences in terms of productivity, turnover and absenteeism. In this study, we analyse the results of a survey we conducted on the job satisfaction of central bank workers, following one of the most popular methodologies to assess job satisfaction: the Job Descriptive Index (JDI). The results show that the levels of job satisfaction in the three central banks studied are overall good. However, the dimension ―opportunities of promotion‖ has a negative assessment in all three banks. This lack of opportunities, together with the work itself, is indeed the main driver of workers wanting to change jobs. We also show that there is a positive relation between education and job satisfaction in two of the three banks. Finally, the years of service seem to impact negatively job satisfaction of central bank workers, an issue of particular relevance for central banks where job duration is usually long.
