Due to constant changes and demands from external forces markets, today's employees are subjected to continuous change in the workplace in order for organisations to stay competitive. Changes include restructuring, downsizing, technological changes and so forth, which result in employees feeling less secure in their jobs compared to employees a few decades ago. This insecurity is a reality in the lives of employees and leads to a whole range of emotions and reactions toward these changes. The primary objectives of this research is to determine the nature of the relationship between job insecurity and affective organisational commitment, and also the nature of the relationship between job insecurity and the general health of employees in a specific petro-chemical organisation (N = 229). The final objective is to determine if work locus of control plays a mediating role in the above mentioned relationships. A cross-sectional survey design was employed. Constructs were measured using the following: the Job Insecurity Questionnaire (JIQ), the Organisational Commitment Questionnaire (OCQ) [where only the affective subscale was interpreted], the General Health Questionnaire (GHQ), the Work Locus of Control Scale (WLCS) as well as a biographical questionnaire. Results indicated that a practically significant relationship of medium effect exists between job insecurity (both dimensions) and work locus of control, and also a practically significant negative relationship between job insecurity (cognitive subscale) and affective organizational commitment and between affective organisational commitment with work locus of control. No other practically significant relationships were found, although the relationship between the variables did prove to be statistically significant. Regression analysis confirmed that work locus of control fully mediate the relationship between affective job insecurity and affective organisational commitment and also between affective job insecurity with general health, whilst partial mediation by work locus of control was found between cognitive job insecurity and affective organisational commitment and cognitive job insecurity and general health. Conclusions and recommendations were made.
