The ever-changing global business environment of today is presenting organisations with numerous challenges and in some instances result in economic and ethical meltdowns. The mining industry, in particular, is faced with a volatile market and consequently mining companies are experiencing increasing financial turmoil coupled with human capital problems resulting in labour unrest and often inoperativeness. As these challenges gain momentum, the mining industry will need to respond through a restructure of operations. Although the mining industry has been faced with a need to restructure before, it has not been faced with this challenge recently. Therefore, only a small portion of management teams holds the skills to respond effectively. For the mining industry in South Africa to adequately address these challenges, leadership will play a pivotal role. Consequently, organisations need a new kind of business leader and leadership should be examined from an authentic perspective. Authentic leadership has been associated with various positive outcomes such as trust in supervisor, psychological safety and work engagement. Both employees and organisations should support one another in order to remain viable. Trust is an important component of effective leadership and building relationships. In order for employees to feel secure and able to adapt to change, organisations should develop an environment which fosters trust and psychological safety and which, in turn, will lead to increased work engagement. The objectives of this study were to examine the relationship between authentic leadership, trust in supervisors, psychological safety and work engagement. In addition, another objective was to examine if trust in supervisor and psychological safety had an effect on the relationship between authentic leadership and work engagement. An available sample of 244 employees was taken from the mining industry in the Free State province. The questionnaires were distributed to employees across all levels in a mining organisation. All of these employees were given the choice to participate in the research. The measuring instruments utilised were the Authentic Leadership Questionnaire, Utrecht Work Engagement Scale, Workplace Trust Survey and Psychological Safety Questionnaire. Descriptive and inferential statistics, Raykov’s rho coefficients, Pearson product-moment correlations coefficients, Mplus and bootstrapping were used to analyse the data. The results indicated that authentic leadership had a statistically significant positive relationship with trust in supervisor as well as psychological safety. Authentic leadership did not have a statistically significant positive relationship with work engagement. The results indicated that authentic leadership had a statistically significant indirect effect on work engagement via trust in supervisor. Authentic leadership did not have a statistically significant indirect effect on psychological safety via trust in supervisor. Furthermore, authentic leadership did not have a statistically significant indirect effect on work engagement via psychological safety. Various recommendations were made for the mining industry as well as for future research. Organisations should understand the impact of authentic leadership on outcomes such as trust, psychological safety and work engagement. Organisations should select leaders who display the four dimensions of authentic leadership as well as implement structured leadership programmes or interventions. Recommendations for future research included utilising longitudinal research designs or diary studies as well as expanding the study to other organisations, industries, and provinces; also including additional sources of data over and above supervisors and subordinates. Future research may also employ a mixed method approach and include other related leadership constructs in the data collection. / MCom (Industrial Psychology)--North-West University, Vaal Triangle Campus, 2015.

One issue that has been neglected and is gaining currency in the organizational citizenship behavior (OCB) literature is the extent to which individuals consider OCB to be part of the job (OCB role definition). A recent meta-analytic review reveals that employees are more likely to perform OCB when they define OCB as in-role rather than as extra-role. However, little attention has been paid to the influences of organizational practices on employee OCB role definition. This neglect is of particular relevance because researchers have argued that how employees view their role obligations are likely to be subject to some purposeful organizational practices. Thus, this paper focuses on the effects of high-performance work systems (HPWS) on employee OCB role definition. This paper adopts multiple theoretical perspectives (e.g., social exchange, organizational identification, ability-motivation-opportunity, and trust) to understand how, why, and when HPWS cause employees to expand their job requirements to include OCBs like helping and voice. Using a multisource data collected at 4 waves from 208 supervisor-employee dyads in Taiwan, I examined the following: (a) the direct effect of employee-experienced HPWS on employee helping and voice role definitions, (b) the mediating roles of employee helping and voice role definitions in the employee-experienced HPWS and actual employee helping and voice relationships, (c) the mediating roles of employee social exchange and organizational identification perceptions toward the organization, as well as employee efficacy, instrumentality, and autonomy perceptions toward helping and voice in the relationships between employee-experienced HPWS and OCB role definitions, (d) the direct effect of employee trust in supervisor on employee helping and voice role definitions, and (e) the moderating role of employee trust in supervisor in the relationships between employee-experienced HPWS and employee helping and voice role definitions. The results confirm the direct effects of employee-experienced HPWS and trust in supervisor, the mediating effects of employee helping and voice role definition, and employee efficacy, instrumentality, and autonomy perceptions toward helping and voice, as well as the moderating effects of employee trust in supervisor, such that employee trust in supervisor strengthened the effects of employee-experienced HPWS on employee helping and voice role definitions when trust in supervisor was high than when it was low. Implications for research and practice are discussed. / Dissertation / Doctor of Philosophy (PhD)

The purpose of this study is to explore the mechanisms of how feedback from supervisor affects innovative work behavior among local government employees in Korea. Another purpose of this study is to explore the mediating roles of trust in supervisor and affective commitment, and the moderating role of risk-taking climate, using various theories, such as organizational support theory, social exchange theory, intrinsic motivation theory, and psychological climate theory. The results from a cross-sectional study based on a sample of 1,699 local government employees from 65 local governments find that feedback from supervisor has a significant direct effect on innovative work behavior. Trust in supervisor and affective commitment significantly mediate the relationship between feedback from supervisor and innovative work behavior. Feedback from supervisor has an indirect effect on innovative work behavior through its influence on trust in supervisor and affective commitment in serial. Risk-taking climate significantly moderates the relationship between affective commitment and innovative work behavior. Lastly, the results of moderated mediation model find that the conditional effects are significant at high levels of the moderator (at one standard deviation above the mean) and at the mean, while the conditional effect was not significant at low levels of moderator (at one standard deviation below the mean) for both two indirect effect paths (feedback from supervisor --> affective commitment --> innovative work behavior, and feedback from supervisor --> trust in supervisor --> affective commitment --> innovative work behavior).
