The job demands-resources model (JD-R model) is an occupational stress model that suggests strain is a response to imbalance between demands on the individual and the resources he or she has to deal with those demands. The JD-R was introduced as an alternative to other models of employee well-being, such as the demand-control model and the effort-reward imbalance model.
The authors of the JD-R model argue that these models "have been restricted to a given and limited set of predictor variables that may not be relevant for all job positions" (p.309). Therefore, the JD-R incorporates a wide range of working conditions into the analyses of organizations and employees. Furthermore, instead of focusing solely on negative outcome variables (e.g., burnout, ill health, and repetitive strain) the JD-R model includes both negative and positive indicators and outcomes of employee well-being.
