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. The JD-R model can be summarized with a short list of assumptions/premises: Whereas every occupation may have its own specific risk factors associated with job stress, these factors can be classified in two general categories: job demands and job resources. Job demands: physical, psychological, social, or organizational aspects of the job, that require sustained physical and/or psychological effort or skills. Therefore, they are associated with certain physiological and/or psychological costs. Examples are work pressure and emotional demands. Job resources: physical, psychological, social, or organizational aspects of the job that are either: functional in achieving work goals; reduce job demands and the associated physiological and psychological cost; stimulate personal growth, learning, and development. Examples are career opportunities, supervisor coaching, role-clarity, and autonomy. Workplace resources vs. personal resources: The authors of the JD-R make a distinction between workplace resources and personal resources. Two different underlying psychological processes play a role in the development of job strain and motivation.
