This study focuses on work engagement and its negative antipode, burnout, as well as their antecedents and consequences. According to the Job Demands-Resources (JD-R) model, two different processes have to be distinguished: a motivational process that links job resources with turnover intention through work engagement, and an energetic process that links job demands and health complaints via the mediating role of burnout. The robustness of the JD-R model was tested in a heterogeneous occupational sample (N = 846). Structural equation modeling analyses yielded a slightly modified model with only exhaustion being indicative of burnout and vigor, dedication along with absorption being indicative of engagement. The results provide evidence for the dipartite structure of the JD-R model. Multi-group analyses revealed the model to be invariant across age and gender. Although strengths of path coefficients and factor loadings differed among white- and blue-collar workers, the basic structure of the model was also confirmed among these subgroups. Therefore, the findings underscore the robustness of the JD-R model.
