This study has two main goals. The first would be the extension of the Job Demands-Resources Model with another factor, namely with vocational fit. The other is to examine the relationship between vocational fit, work engagement and burnout, within the same framework. For this purpose, a total of 106 non-randomly selected participants have been invited to fill in a set of four questionnaires, written in Romanian. One out of the two hypotheses have been supported by the evidence. More specifically, the statement that vocational fit has incremental validity, over and above job demands and job resources, in predicting burnout and engagement has been confirmed. However, the assumption that vocational fit mediates the relationship between burnout and work engagement, has not.
