In today’s competitive business environment, human resources are one of the most critical assets particularly for service-focused organizations. Consequently, employees’ morale has become invaluable for maintaining outstanding organizational performance and retaining employees. One of the most important factors which may affect employees’ satisfaction is workplace bullying from employers and colleagues at large. It is considered a negative and unethical issue which may degrade, humiliate and create a risk to a healthy working environment. Therefore, the main objective of this research is to investigate the extent to which workplace bullying may affect the organizational outcomes of a sample of five-star hotels in Egypt. Two questionnaires were distributed among the subjects of the sample; bell desk staff, kitchen stewards and head departments. The results of this research confirmed that there is a correlation between workplace bullying, employees’ morale and turnover intentions but, showed no correlation between workplace bullying and employees’ work performance.

This study focused on corporate governance and performance of selected Nigerian multinational firms from 2012 to 2016. Specifically, the study focused on the effect of board size, activism and committee activism on return on asset and firm growth rate. Secondary data collected from four multinational firms were analyzed via static panel estimation techniques. While board size and board activism exerted significant negative impact on return on asset, committee activism exerted insignificant impact. The results of the study further showed that board size and board activism exert insignificant negative impact on firm’s growth rate, while committee activism insignificantly spurs firm’s growth rate. Decisively, discoveries from this study reflect that corporate governance has significant negative impact on return on asset, but has insignificant influence on the growth rate of Nigerian multinational firms. Based on these findings, the authors recommended that corporate governance dynamics in firms world over should be reconsidered, such that it gives credence to more than just numbers of persons or meetings held, but the main reasons and deliberations in such meetings. It was also recommended that excessive increase in magnitude or frequency of meetings held by board of directors cum committee should be avoided.

Risk management is one of the prominent issues which are pivotal to the success of a business and may adversely affect profitability if not properly practised. Therefore, the main objective of this paper was to determine risk management practices in manufacturing SMEs in Cape Town. The research conducted was quantitative in nature and constituted the collection of data from 74 SME leaders, all of whom had to adhere to a list of strict delineation criteria. All data collected were thoroughly analyzed through means of descriptive statistics. From the findings made, it is clear that SMEs in the manufacturing sector do in fact understand risk management initiatives applicable to ‘manage’ their respective businesses towards sustainability, but not to a large extent. It was found that respondents are unaware of the elements which make risk management effective, which ultimately aids to the development of problems for SMEs. All employees, managers and owners must coordinate their efforts together to identify and manage organizational risks within their ambit to obtain total risk coverage, as well as provide assurance that these risks are effectively managed from a coordinated approach. Further studies may be carried out to identify measures that can be taken to improve the effectiveness of risk management practices in SMEs.
