    ENGLISH SUMMARY: Shift work is an important aspect of working time that is often associated with many negative outcomes. Although there are economic, technical, and social benefits for organisations in the use of shift work schedules, these benefits are conflicted by the social and health impairments for workers. Since the use of shift work is escalating, it is increasingly important for organisations to understand what the impact of shift work on their workers is and to implement interventions that aim to prevent, eliminate, or manage the challenges associated with it. The purpose of this research study was therefore to explore salient variables that contribute to variance in burnout, engagement, and general health in South African shift workers. Using the framework of the Job Demands-Resources model, this quantitative study aimed to test the relationships between the five core job characteristics as described in the job characteristics model, psychological capital, non-standard work schedules and chronotype with the engagement, burnout, and general health of shift workers. An ex post facto correlational design was used, and data was collected from a non-probability sample of 175 South African shift workers using a survey method. Variables were measured using the MOS 36-Item Short-Form Health Survey (RAND-36), the Utrecht Work Engagement Scale (UWES-9), the Oldenburg Burnout Inventory (OLBI), the Job Diagnostic Survey – Revised (JDS-R), the Psychological Capital Questionnaire (PCQ-12), three questions for work schedule and the Horne – Őstberg Morningness Eveningness Questionnaire (MEQ). Data analysis made us of the PLS-SEM method. The findings indicated that job characteristics are antecedents of PsyCap. These personal resources in turn buffered against burnout and led to higher levels of engagement which fostered the psychological health of workers. Burnout was also found to be negatively related to both physical and psychological health. On the other hand, the relationship between non-standard work schedules and burnout, along with the moderating effect of chronotype on this relationship, was not found to be statistically significant. Furthermore, the relationship between job characteristics and engagement, as well as engagement and physical health, was also not found to be statistically significant. This study concluded that interventions aimed at developing PsyCap among employees could assist in transforming organisations to significant sources of happiness, satisfaction, meaningfulness, and general well-being.
