dc.description.abstractENGLISH 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.en_ZA
dc.description.abstractAFRIKAANSE OPSOMMING: Skofwerk is 'n belangrike aspek van werktyd wat dikwels met baie negatiewe resultate geassosieer word. Alhoewel daar ekonomiese, tegniese en maatskaplike voordele vir organisasies is in die gebruik van skofte, is hierdie voordele in teenstryd met die maatskaplike en gesondheidsvoordele vir werkers. Aangesien die gebruik van skofwerk aan die toeneem is, is dit toenemend belangrik vir organisasies om te verstaan wat die impak van skofwerk op hul werkers is en om ingrypings te implementeer wat daarop gemik is om die uitdagings wat daarmee gepaard gaan te voorkom, uit te skakel of te bestuur. Die doel van hierdie navorsingstudie was dus om opvallende veranderlikes te verken wat bydra tot veranderings in uitbranding, betrokkenheid en algemene gesondheid by Suid-Afrikaanse skofwerkers. Aan die hand van die raamwerk van die “Job Demands-Resources” -model, het hierdie kwantitatiewe studie ten doel gehad om die verwantskappe tussen die vyf werkseienskappe soos beskryf in die “job characteristics”-model, sielkundige kapitaal (“psychological capital” - PsyCap), nie-standaard werkskedules en chronotipe te toets in terme van die betrokkenheid, uitbranding, en algemene gesondheid van skofwerkers. 'n Ex post facto korrelasie-ontwerp is gebruik, en data is ingesamel uit 'n nie-waarskynlikheidsteekproef van 175 Suid-Afrikaanse skofwerkers deur 'n opnamemetode te gebruik. Veranderlikes is gemeet deur gebruik te maak van die MOS 36-item Kortvorm Gesondheidsopname (RAND-36), die “Utrecht Work Engagement Scale” (UWES-9), die “Oldenburg Burnout Inventory” (OLBI), die “Job Diagnostic Survey – Revised” (JDS-R), die “Psychological Capital Questionnaire” (PCQ-12), drie vrae vir werkskedule en die “Horne – Ostberg Morningness Eveningness Questionnaire” (MEQ). Data-analise het van die PLS-SEM-metode gebruik gemaak. Die bevindinge het daarop gedui dat werkseienskappe die voorlopers van PsyCap is. Hierdie persoonlike hulpbronne het op hul beurt ʼn buffer teen uitbranding gebied en het gelei tot hoer vlakke van betrokkenheid, wat die sielkundige gesondheid van werkers bevorder het. Daar is ook gevind dat uitbranding negatief verband hou met sowel fisiese en sielkundige gesondheid. Aan die ander kant is gevind dat die verband tussen nie-standaard werkskedules en uitbranding, saam met die modererende effek van chronotipe op hierdie verhouding, nie statisties betekenisvol is nie. Verder is daar ook nie gevind dat die verband tussen werkseienskappe en betrokkenheid, sowel as betrokkenheid en fisiese gesondheid, statisties betekenisvol is nie. Hierdie studie het tot die gevolgtrekking gekom dat ingrypings wat gemik is op die ontwikkeling van PsyCap onder werknemers kan help om organisasies te omskep in beduidende bronne van geluk, tevredenheid, betekenisvolheid en algemene welstand.af_ZA
