MCom (Industrial Psychology) at the Vaal Triangle Campus of the North-West University, 2017 The public health care sector encompasses a volatile working environment that faces an array of challenges. Employees in this environment are often overworked and conduct their work under negative circumstances due to a lack of proper management, a lack of resources and the inability of the employees to remain motivated and engaged. According to literature, the Department of Health has recently included the term ‘leadership’ as one of its main drivers to overcome the obstacles faced by individuals in this sector. In authentic leadership, specifically, the ability of the leader to be transparent and honest with others can have phenomenal benefits, especially in such a demanding work environment. The objective of this study was to investigate the relationship between authentic leadership and work engagement through the indirect effects of trust. The study was cross sectional in nature, with a non-probability convenient sampling technique being used. The total sample (N = 633) was obtained. The measuring instruments that were used in this study are the authentic leadership inventory (ALI), the work engagement scale (UWES) and two of the three subconstructs of the workplace trust survey (WTS). In order to conduct the statistical analysis, structural equation modelling was used for the development of the measurement and structural models. These models were used to test the hypotheses in the study. In addition to the measurement models, correlations among latent variables were determined and the structural model analysed the strength and direction (regression) between the latent variables as well as possible indirect effects. In the measurement model, it was found that a significant relationship exists between authentic leadership and work engagement, however the direction of authentic leadership preceding work engagement could not be confirmed by the structural model. The results of the study found that authentic leadership through trust in co-worker had a greater indirect effect on work engagement than through trust in supervisor, although both showed a significant impact.

MA (Human Resource), North-West University, Vanderbijlpark Campus, 2021 Teachers are without a doubt the most critical members of our society. They play a significant role in the country's economic growth and the reason people succeed in the world. The profession requires commitment, dedication, and passion. Therefore, positive emotions are crucial in their field of work. Not many studies focused on positive behaviour and its impact on individual work performance of teachers. Most of the studies focused on the negative factors experienced by teachers. It appears that research on positive behaviour, specifically the relationship between psychological capital happiness and individual work performance from a cross sectional perspective is needed. The study conceptualised psychological capital, happiness and individual work performance from a theoretical perspective and the review established that, limited research has been done on the relationship between psychological capital, happiness, and individual work performance in public high schools in South Africa. The aim of the study was to investigate the relationship between psychological capital, happiness, and individual work performance amongst public high school teachers in the Free State province of South Africa. A cross sectional survey design was used with the sample (N-260) public high school teachers. Psychological capital questionnaire (i.e., self- efficacy, hope, optimism and resilience), orientation to happiness questionnaire (i.e., pleasure, meaning and engagement) and individual work performance (i.e., task performance, contextual performance and counterproductive behaviour) were used to measure the constructs. The specific objectives of the study were. • To understand the relationship between psychological capital and happiness amongst public high school teachers in the Free State Province • To understand the relationship between happiness and individual work performance amongst public high school teachers in the Free State province • To understand the relationship between psychological capital and individual work performance amongst public high school teachers in the Free State Province and • To investigate whether psychological capital indirectly affects individual work performance through happiness amongst public high school teachers in the Free State Province The results indicated that psychological capital had a significant relationship with happiness. There was a relationship between happiness and individual work performance. Psychological capital had a positive relationship with individual work performance. Inverse to what was expected, psychological capital had no indirect association with individual work performance through happiness. The results contribute to literature on the importance of psychological capital and happiness in the education sector. Masters
