Job Requirements - Overview of Resource Theory

Abstract

 The Job Demands-Resources Theory (JD-R theory) was proposed by Demerouti et al. in 2001 and combines a number of related theories such as the Resource Conservation Theory, the Job Demands-Control Theory, and the Payoff-Return Imbalance Theory. The theory states that when job demands are too high, employees need to put in extra effort to achieve their work goals, which can lead to physical and mental exhaustion and affect overall health and performance. In addition, insufficient work resources can also pose a barrier to employees' achievement of their goals, which in turn can lead to job detachment and negative emotions. With the development of occupational health psychology, work engagement has been recognised as a positive dimension of well-being and has been incorporated into this theoretical framework.Job demands include the pressures and challenges that employees have to cope with in completing their work, while job resources are the support and tools that employees can utilise when facing these demands. By analysing both, job demands-resources theory provides an important framework for understanding employees' work experiences, and guides companies in making scientific decisions about improving employee well-being, engagement and performance. Specifically, job demands can be categorised into challenging demands, which promote personal growth, and hindering demands, which can act as barriers. Job resources, on the other hand, play a positive role in helping employees to achieve their goals, relieve stress, and promote personal development.
