Dark personality traits and job performance of employees: The mediating role of perfectionism, stress, and social media addiction

This research aims to assess direct and indirect influences of organizational culture on job performance, as well as to evaluate the impact of each sub-element of organizational culture on such performance. It is argued that employees performance derives, on the one hand, from a long-term perspective related to changes that organizations manage and implement during their process of growth. A second dimension of organizational culture can be given through organizational values, routines and distinctive aspects of culture that allow organizations to create solid competitive advantages. Since most studies in this field were held in Western work cultures, this paper will be devoted to the analysis of this relationship within an Arabic cultural environment and more specifically within a Saudi context. A quantitative study tool, based on a comprehensive research questionnaire, was used and the sample was selected from various government departments being operative in Alkharj. The findings indicate a positive relationship between organizational culture and job performance. Likewise, four organizational culture sub-elements, namely Managing Change, Achieving Goals, Coordinating Teamwork and Cultural Strength, were found affecting positively on job performance, but with varying and distinct intensity. Only Customer Orientation was found negatively associated with job performance.

Performance appraisal is the bedrock of talent management and has received much attention from scholars and researchers alike in their pursuit to develop accurate, objective, and robust Performance Management Systems (PMS). Through survey questionnaire the present study examines the prevalence of idiosyncratic rater biases on the performance appraisal systems and evaluates the measure of its impact. The correlations between the personality traits and the similarities of the raters’ workplace characteristics with the raters’ performance ratings are also determined. The study has provided empirical evidence of the manifestation of idiosyncratic rater bias in the company under study. The idiosyncratic rater tendencies showed a significant impact on performance ratings. It was seen that about one-third of the variations in the ratings were resultant of the idiosyncratic factors, such as similarities in the personality traits and workplace identities. It is also found that there exists a positive correlation between the similarities in the identities, as well as the personality traits of the raters and the ratees, and the way the rating awarded by the rater.

The study aims to examine the effect of employee loyalty on job performance in Bahrain. Further, it investigates the mediating effect of job satisfaction on the relationship between employee loyalty and job performance. One hundred two participants employed by Zain company were selected through an online convenience sampling technique. The study chose Zain, a telecommunication company in Bahrain, due to easy access to employees, interest in studying company culture/methods, collaboration opportunities, and Zain’s reputation for innovation. SmartPLS4 was used to investigate potential correlations between employee loyalty and job performance and how job satisfaction indirectly affects employee loyalty and job performance. Findings show that employee loyalty significantly influences job performance and job satisfaction. Further, job satisfaction is significantly associated with job performance. In terms of mediating effect, the study found that job satisfaction significantly influences the relationship between employee loyalty and job performance. Every variable studied had an impact on job performance. As a result, the current study’s hypotheses are all confirmed. The model of the study is well fit, as the R-square is greater than 51%. The main contribution of this study is the insight that job satisfaction is a substantial mediator of the relationship between employee loyalty and job performance. Through theoretical and practical contributions, this study offers valuable implications that might benefit managers at companies, including Zain company, as well as interested readers and researchers.
