The aim of the study was to investigate whether statistically and practically significant positive relationships exist between intrinsic motivation, social support and work engagement of shift workers in a South African Chemical Company. The expected outcome was to find statistically and practically significant positive correlations between these variables for these workers. A cross sectional survey was conducted among a sample of 207 shift workers from a South African Chemical Company. Data was collected by means of existing standardised and validated questionnaires, to measure intrinsic motivation (six-item measure) validated by Kuvaas and Dysvik, 2009, perceived social support (Work Experiences Scale, May, Gilson, & Harter, 2004), and work engagement (Utrecht Work Engagement Scale, Henn & Barkhuizen, 2009; Shimazu & Schaufeli, 2009). The statistical analysis included descriptive statistics, and Pearson product-moment correlation coefficients. The results showed that there were statistically and practically significant positive relationships between these variables for this sample group / Industrial and Organisational Psychology / M. Com.
