Tertiary institutions in South Africa have experienced radical changes in the past decades, especially due to the change from technikons to universities of technology. These changes created new mental and emotional demands for academic staff and placed them under additional pressure. Problems experienced by tertiary institutions include constantly changing systems, students from underprivileged backgrounds and decreased subsidies from the state. These factors could lead to role overload and role conflict. The objective of this research was to examine the relationships between individual indicators of work climate (job challenge demand, role overload and role conflict, job satisfaction and pay satisfaction and social support) and turnover intention. Further objectives included empirically determining if these indicators of work climate can be used to predict turnover intention and to determine if social support plays a moderating role in the translation of work climate in turnover intention. A cross-sectional survey design was used. A convenience sample was taken from a South African university of technology. Measuring instruments for all the variables of interest were administered. Descriptive statistics were used to analyse the data. Finally, a structural equation model was developed to explain the relations between the variables. The results obtained for the scales proved that four of the seven specific measuring instruments are reliable in terms of their specific use for employees in a South African tertiary institution. Job challenge demand, quantitative role overload and role conflict were less reliable. Results showed that when an employee feels that he/she has too much to do in too little time, or if the task is too difficult to complete, he/she will experience lower levels of job satisfaction which in turn may lead to higher levels of turnover intention. Social support from the supervisor and colleagues increase job satisfaction. A moderating effect for social support between work climate (role characteristics and satisfaction) and turnover intention was demonstrated. By way of conclusion, recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2008.

The South African mining industry is facing rising levels of skills shortage. According to reports, there are a number of reasons for this, one being the low number of graduates who enrol for engineering related qualifications versus the number of graduates who eventually graduate with an engineering qualification. More emphasis needs to be placed on bursaries for university candidates, as well as training in organisations, to groom graduates in this field. The main purpose of this study was to determine the relationship between job characteristics, communication with the manager, organisational commitment, social support and job satisfaction for a sample of employees in South Africa, and specifically to determine whether social support plays a moderating role in this relationship. The participants were a convenience sample of trainees in a mining training academy, in the North–West Province. Participants’ informed consent was sought by explaining what the general purpose of the study is as well as including on the cover page of the questionnaire information around details of the study. Participants had the option of either posting the questionnaires after completing it in their own time (stamped envelope was supplied) or handing the completed questionnaire into their human resource department. This method allowed everyone to complete the questionnaire in their own time. Regarding the relationship between job characteristics (i.e. job autonomy, job challenge, and communication with the manager); all were positively correlated to the outcome variable, namely job satisfaction. None of the interaction terms were significant predictors of the outcome variable (job satisfaction). A conclusion can be drawn from this that social support does not have a moderating effect on the relationship between the measured independent variables (job characteristics and manager communication) and the outcome variable (job satisfaction). However, when only social support from supervisor and colleagues and the job characteristics were considered, it was seen that job autonomy, feedback and social support from colleagues are significant predictors of job satisfaction. This finding indicates that it is not only important for trainees to experience autonomy in the execution of their tasks, but that they also need collegial support and good feedback about such performance in order to experience job satisfaction. In conclusion, recommendations for future research were made. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2012.

Dans cette thèse, j’étudie l’impact des inégalités salariales horizontales sur la performance des commerciaux. J’explore plus particulièrement les coûts relatifs aux comparaisons dont sont l’objet ceux qui sont considérés comme des références dans la force de vente. Grâce à des données relatives à la rémunération et à la performance de plus de 34000 commerciaux, et aux marques qu’ils vendent, je montre que le pouvoir des marques peut se substituer à la rémunération et contrecarrer l’effet négatif des inégalités salariales sur la performance. Par ailleurs, mes résultats suggèrent que la qualité du travail commercial peut également remplacer la rémunération et ainsi influencer la relation entre inégalités salariales et performance. De plus, je décris l’effet de la structure du capital des entreprises sur la gestion de la performance des forces de vente. Je conclus cette étude en montrant comment les responsables devraient tirer partie de leurs marques et de leurs activités commerciales, puisque la manière dont de nombreuses organisations commerciales rémunèrent leurs talents commerciaux se traduit par une augmentation de la dispersion des salaires. / This dissertation examines how horizontal pay inequalities in sales organizations impact salespeople’s performance. More specifically, I explore costs that arise through social comparisons with salient targets within sales organizations. I use compensation and performance data of more than 34,000 salespeople as well as data pertaining to the brands they sell, to show that brand power can substitute for pay and counteract the detrimental effect of pay inequality on performance. Moreover, my results suggest that job challenge can also act as a surrogate for pay, thereby affecting the relationship between pay gaps and performance. Further, I describe the effect of organizational ownership structure on salespeople’s performance management. Given that many sales organizations reward better performers by heightening pay dispersion, decision makers should carefully leverage their brand portfolio and sales team job assignments to soften the impact of pay gaps on salespeople’s performance.

Global growth in mining activities has resulted in stiff competition for talented employees and characterised the mining industry with high turnover rates. The South African mining environment has not been an exception to this phenomenon. The aim of this study was to inform the design of talent retention strategies through determination of turnover intention predictors and exploration of the turnover process experienced by employees. The study hypothesised that job satisfaction and affective organisational commitment mediate the effect of overall justice, centralisation, trust and job challenge on turnover intentions. A cross-sectional survey design with a random sample of trainers and learners from a South African gold mining company was used (n=171 and n=230, respectively). Results indicate that job satisfaction mediates the effect of centralisation on turnover intention for learners. Only job satisfaction directly predicts turnover intention for trainers, and overall justice and trust play a direct role in the prediction of turnover intention for learners. It was also found that job challenge predicts job satisfaction for trainers, whilst job challenge, centralisation and trust predict job satisfaction for learners. Therefore, to retain trainers, the mining company should focus on enhancing those factors that facilitate job challenge perceptions and job satisfaction. In retaining learners, its thrust should be increasing job challenge, decentralisation, overall justice, trust and job satisfaction. / Thesis (M.A. (Industrial Psychology))--North-West University, Potchefstroom Campus, 2011.

Job insecurity in the workplace has become an increasingly important trend in organisational research. The appraisal of job insecurity by individuals plays a significant part in how reactions manifest in the experiences of workplace stressors, job satisfaction, positive and negative work attributes and social support. However, there is a lack of research regarding specific workplace stressors at work leading to certain outcomes like safety behaviour, turnover intention and mental health, especially within a South African working context. Job insecurity has also been classified as a workplace stressor. The existence of other stressors tends to increase the ultimate effect of insecurity for the individual. The attempts from organisational management to manage this phenomenon are therefore crucial in decreasing the negative effects of job insecurity and increasing the productivity of the organisation. In order to measure the job insecurity levels of employees, it is important to make use of valid and reliable job insecurity measures. An absence of empirical research on validity and reliability studies in terms of job insecurity in South African is evident. The main objectives of this research were: 1) to establish the psychometric properties of a measure of job insecurity in a selected gold mining company in South Africa; 2) to determine the influence of job insecurity and work stress (i.e. role conflict, clarity and overload) on worker safety performance and if coping could moderate this; 3) to investigate the theoretical and empirical relationships between job stressors (task completion ambiguity and task quality ambiguity), competency demands, employability perceptions, job satisfaction and turnover intention over time, and 4) to investigate if social support has a mediating effect between positive interpersonal attributes, negative interpersonal attributes, job insecurity and subsequent health. To achieve the first objective, a cross-sectional design was used (N = 566), including various business units of a South African-based gold mining company. The assessment of the psychometric properties of a measure of quantitative and qualitative job insecurity for employees was determined through construct (structural) equivalence, exploratory factor analysis and multivariate analysis of variance to calculate the comparison of the factor structure for the different cultural groups. For qualitative job insecurity, the scale shows low equivalence for the African languages group. Statistically significant differences were found between the levels of job insecurity of employees in terms of gender. The second objective, concerning the investigation into the relationship of work stress and job insecurity with unsafe behaviour at work, was achieved with across-sectional survey design (N = 771). The hypothesised model included the influence of role conflict, role ambiguity, role overload, and job insecurity on unsafe work behaviour. Coping was introduced as a moderator in this relationship. The results indicated that when employees experience work stress and job insecurity, their safety compliance is low. This relationship was also moderated by a coping strategy of Avoidance. To achieve the third objective, a longitudinal study was conducted and data was gathered by means of an electronic survey, with 771 employees participating at Time 1, and 345 participating at Time 2. Results for predicting employees’ turnover intentions, experience of task completion and quality ambiguity, external employability and job satisfaction made a direct contribution in predicting their turnover intention. No mediating role of job satisfaction between job stressors, competency demands and employability perceptions on the one hand and turnover intentions on the other hand, were found. Addressing the fourth objective in investigating the moderating role of social support between the relationship of experiencing positive interpersonal (communication with the manager and feedback), negative interpersonal experiences (powerlessness and interpersonal conflict), job insecurity (quantitative and qualitative) and health, was met with a longitudinal random sample of employees in different business units in one selected multi-national mining company based in South Africa (N = 771). Results for these employees indicated that all the proposed variables, except feedback from the manager, were statistically significantly related to health. No moderating effect for social support could be found over time, but it was shown that interpersonal conflict at work is a longitudinal predictor of employee health. By way of conclusion, the implications of the research were discussed and recommendations for managers and for future research were made. / Thesis (PhD (Industrial Psychology))--North-West University, Potchefstroom Campus, 2013.
