dc.description.abstractEmployees in the Occupational Risk Division (ORD) of a large petrochemical company experience many difficult situations on a regular basis. This division of the company comprises the emergency services, the security and the occupational health divisions of the company. Even though every precaution is taken to ensure the safety of employees in the company, accidents and incidents do happen. The employees of the ORD are confronted with gruesome accidents, dangerous accident scenes where they have to enter when everyone else is evacuated, and security breeches where they may have to enter and resolve serious conflict situations. The possibility that their work climate may contributed to their mental health status is suggested. It is suspected that the stress of the job affects the mental health of the employees of the OCD, and ways need to be found to reduce these effects. The objective of this research was to determine the relationship between core self-evaluation’s, role overload, powerlessness and health indicators of employees in the ORD of a large petro-chemical company and to determine whether core self-evaluation’s act as a moderator in the relationship between role overload and powerlessness on the one hand and health indicators on the other hand. A cross-sectional design was used. The sample consisted of 299 employee’s fi-om the Occupational Risk Division of the organization. Age, gender and level of education were included as control variables. A comprehensive survey containing the measuring instruments was administrated. Descriptive statistics and inferential statistics were used to analyse the data. Results obtained indicated that some of the scales were not reliable. Powerlessness was dropped from the analysis and qualitative and quantitative role overload were collapsed into a total overload measure. The results showed that a negative relationship exists between role overload and core self-evaluations. A positive relationship exists between role overload and neuroticism, poor health and depression. Self-esteem, self-efficacy and locus of control are negatively related to neuroticism and health, and neuroticism is positively related to poor health. Depression was predicted by experiences of overload, levels of self-efficacy, locus of control and negative affect (Neuroticism). General health was predicted by experiences of overload, locus of control, neuroticism and the interaction between overload and self-esteem. None of the scales predict medication use to a significant degree. Results further indicated that only self-esteem acts as a moderator in the relationship between role overload and general health, but none of the variables of core self-evaluation’s act as a moderator between role overload and depression or between role overload and the use of medication.
