As emerging knowledge management platforms, enterprise social media (ESM) provide an important way for employees to engage in knowledge sharing and information communication within their organization. However, the question of how to encourage employees to engage in continuous knowledge sharing rather than knowledge hiding on ESM has not received sufficient attention from scholars. In contrast to previous studies that focused on a single theory perspective and a single knowledge behavior, in this study, we took a user cognition and emotion perspective and constructed a mechanism model for the impact of knowledge sharing and knowledge hiding among employees on ESM based on social cognition theory and emotion as social information theory. A total of 240 valid questionnaires were collected and used to empirically test the model. The results indicate that reciprocity and outcome expectancy have a significant positive effect on employees\' knowledge-sharing behavior, while reciprocity and trust have a significant negative effect on employees\' knowledge-hiding behavior. Positive emotions play a positive (enhancing) moderating role on the path between outcome expectancy and knowledge-sharing behavior, while negative emotions play a negative (weakening) moderating role on the path between reciprocity and knowledge-hiding behavior, as well as between trust and knowledge-hiding behavior. By incorporating employee emotions into the framework of social cognition\'s impact on employee knowledge behavior, this study enriches theories related to enterprise social media, knowledge management, and user behaviors. Our research findings have practical implications for guiding employees to engage in positive knowledge sharing and reducing knowledge hiding on enterprise social media.

Modern organizations assert that cynicism and organizational design provide advantages for knowledge-intensive settings. However, organizational crises may lead to resource shortages, prompting increased knowledge hiding (KH) among workers for competitive edge. Therefore, current study aims to examine the influence of organizational design and cynicism on job performance with organizational justice and KH through the moderating effect of servant leadership. Convenience sampling technique was used for data collection from 730 manufacturing organization employees via a survey questionnaire and data were analyzed with AMOS (28.0). Findings showed that KH\'s behavior negatively influenced by organizational design and positively influenced by cynicism. The current study also validates that higher management needs to practice advanced organizational justice to improve performance that drastically generates justice practices and reduces KH within the firms. Moreover, deploying servant leadership helps to control the cynicism, and employees start practicing knowledge-sharing behavior that significantly contributes to the performance.

Negative behaviors at the workplace always disturb the management of the firms. This research investigates the link between the dark triad and various types of Knowledge hiding (Evasive hiding, Playing dumb, and Rationalized hiding) in firms. In addition, this study explores perceived organizational politics as a mediator. The design of this study is quantitative and positivist. The data were collected in three waves (45 days gap) with a random sampling approach from 383 personnel/staff working in Chinese commercial banking firms. The data were analyzed using the partial least squares structural equation modeling (PLS-SEM) technique and Smartpls-4 software. This study confirms that dark-triad has a positive relation with knowledge hiding, except psychopathy and Machiavellianism, which have no significant correlation with playing dumb and evasive hiding, respectively. Perceived organizational politics significantly mediate the association between dark triad personality traits and the types of knowledge hiding. Employees with political skills and a trust-based culture can counter the dark-triad personalities and discourage the knowledge-hiding culture. For effective management of knowledge-hiding issues in firms, codifying implicit and explicit Knowledge and developing knowledge repositories can discourage a knowledge-hiding culture.

OBJECTIVE: The purpose of this paper is to highlight the joint impact of competitive culture and knowledge behaviors (sharing, hoarding and hiding) on workplace happiness among healthcare professionals. It addresses a literature gap that critiques the development of happiness programs in healthcare that overlook organizational, social and economic dynamics. The study is based on the Social Exchange Theory, the Conservation of Resources Theory and the principles of Positive Psychology.
METHODS: The study analyzes a linear relationship between variables using a structural equation model and a partial least squares approach. The data are sourced from a survey of 253 healthcare professionals from Portuguese healthcare organizations.
RESULTS: The data obtained from the model illustrate a positive correlation between competitive culture and knowledge hoarding as well as knowledge hiding. Interestingly, a competitive culture also fosters workplace happiness among healthcare professionals. The complex relationship between knowledge behaviors becomes evident since both knowledge hoarding and sharing positively affected these professionals\' workplace happiness. However, no direct impact was found between knowledge hiding and workplace happiness, suggesting that it negatively mediates other variables.
CONCLUSIONS: This research addresses a previously identified threefold gap. First, it delves into the pressing need to comprehend behaviors that enhance healthcare professionals\' workplace satisfaction. Second, it advances studies by empirically examining the varied impacts of knowledge hiding, hoarding and sharing. Finally, it sheds light on the repercussions of knowledge behaviors within an under-explored context - healthcare organizations.

UNASSIGNED: Grounding on relative deprivation theory, this study aimed to investigate the relationship between perceived overqualification (POQ) and knowledge hiding. Furthermore, this study investigated the mediating role of job boredom and the moderating effect of job crafting.
UNASSIGNED: /Methodology/Approach: This study employs Hayes\' PROCESS model to analyze data obtained from 374 employees working in the hospitality and tourism industry.
UNASSIGNED: The results indicate a positive relationship between POQ, job boredom, and knowledge hiding. These findings suggest that job boredom mediates the relationship between POQ and knowledge hiding. Furthermore, the study showed a moderated mediation path wherein the interaction effect of POQ and job crafting on knowledge hiding was mediated by job boredom.
UNASSIGNED: Data were collected from the hospitality and tourism industry, limiting the generalizability of the findings to other sectors. Additionally, the study relied on self-reported measures, which may have resulted in a bias.
UNASSIGNED: Conduct thorough job fit assessments during the hiring process to ensure that candidates\' qualifications align closely with job requirements. By matching employees\' skills and experiences to their job, organizations can reduce perceived overqualification, which may lower job boredom and knowledge hiding tendencies.
UNASSIGNED: This study\'s focus on person-job misfits adds a new layer of insight into employee experiences in the workplace. By examining how mismatches between individuals and their roles contribute to job boredom and knowledge hiding, this study highlights the importance of aligning job responsibilities with employee skills, qualifications, and preferences.

Based on the social exchange theory and conservation of resources theory, the present research aimed to study the role of reciprocity beliefs in the relationship between workplace ostracism and knowledge hiding among college teachers. The study was conducted on a sample of 490 college teachers (i.e., 250 men & 240 women). The sample\'s age ranged from 24 to 58 years (M = 28, SD = 1.30). Psychometrically strong measurement tools were used to measure the constructs. Simple linear regression analysis demonstrated workplace ostracism as a significant positive predictor of knowledge hiding for college teachers. Mediation analysis demonstrated that negative and generalized reciprocity beliefs significantly mediated the relationship between workplace ostracism and knowledge hiding. This research will help organizations develop clear policies that encourage knowledge sharing and provide support systems for instructors with experience of ostracism. Limitations and suggestions of the current study for further empirical endeavors have also been discussed.

UNASSIGNED: This study explored the influence of team member exchange on employees\' knowledge hiding behaviors via job embeddedness and work alienation, with learning goal orientation acting as the boundary condition.
UNASSIGNED: ology: This study adopted a quantitative multi-study research methodology to validate the proposed hypotheses, combining a time-lagged field study with 459 in-service employees and a scenario-based experiment with 128 university students at a northern university in China.
UNASSIGNED: In Study 1 (field study), team-member exchange was negatively associated with knowledge hiding, and job embeddedness and work alienation mediated this relationship. Perceptions of learning goal orientation can amplify the effect of team-member exchange on job embeddedness and work alienation, which in turn reduces knowledge hiding behaviors. A subsequent experiment (Study 2) almost replicated and supported these findings, but work alienation did not play a role as an intermediary in the relationship between team member exchange and knowledge hiding behavior.
UNASSIGNED: Managers should stimulate social exchanges among team members to inhibit knowledge hiding behaviors and prioritize individuals exhibiting higher learning goal orientations when deciding whom to hire.
UNASSIGNED: This research identifies and rationalizes how (underlying mechanisms) and when (contingencies) team-member exchange can make a difference in employees\' knowledge hiding behaviors, expanding and advancing further research on the knowledge hiding phenomenon from a team perspective.

Impostorism and knowledge-hiding behaviors negatively impact employees and organizational performance. This study examines the association between impostor leaders and knowledge hiding (evasive hiding, playing dumb, and rationalized hiding). Attachment avoidance is discussed as a mediator between impostor leaders and knowledge-hiding. For quantitative analyses, this study collected the data from 429 individuals with two time lags by sharing the survey instrument link on different organizations\' randomly selected official media pages. After obtaining approval from the administrators of these pages, leaders and subordinates from these organizations were asked to participate in the study. The partial least squares structural equation modeling method is employed with Smartpls-4 software for data analyses. The findings indicate that impostor leaders promote knowledge hiding in subordinates. However, impostor leaders highly promote rationalized hiding behavior in subordinates. Attachment avoidance mediates the relationship between the impostor leader and knowledge-hiding behaviors. However, the highest mediation relationship exists between an impostor leader and playing dumb behavior in subordinates. This study strengthens the generalizability of the social exchange theory. The implications mentioned in this study are beneficial in understanding and dealing with the Impostorism and knowledge-hiding phenomena.

This study sheds light on the literature on knowledge-hiding behavior in organizations and highlights a better and deeper understanding of the reasons for giving rise to knowledge hiding. In recent decades, knowledge hiding has been subjected to numerous studies in systematic literature reviews and organizational management regarding its impact on outcomes such as individual and organizational performance; however, the mechanism by which knowledge hiding is influenced by antecedents and the process of leading knowledge hiding has not been actively verified. In addition, most previous studies have classified knowledge hiding into one-factor or three-factor dimensions: evasive hiding, playing dumb, and rationalized hiding. To address these issues and limitations, we aimed to conduct empirical research, which have focused on four new dimensions (playing dumb, evasive hiding, rationalized hiding, and procrastination) of knowledge-hiding behavior. Unlike previous research, we provide a research framework for the process of hiding knowledge and verify the significance of the research model, drawing on the social exchange theory and conservation of resources theory to explore and verify the process of hiding knowledge. Specifically, we argue that knowledge hiding is caused by exploitative leadership, and psychological distress as mediators in the relationship between these two variables. Moreover, the moderating and mediating effects of leader incivility were verified. To empirically test the research model, a survey was conducted with 287 employees from small- and medium-sized enterprises in China. Partial least squares structural equation modeling (PLS-SEM), SPSS PROCESS, and AMOS software were used for statistical analyzes. The findings provide evidence that exploitative leadership positively influences both psychological distress and the four dimensions of knowledge hiding. In addition, the mediating effect of psychological distress and the moderating effect of leader incivility were verified and shown to be statistically significant. Based on these findings, the theoretical and practical implications, limitations, and directions for future research are discussed. Overall, the most important contribution is expanding the research field, as this is the first empirical study on the four dimensions of knowledge hiding.

This study investigates the association of knowledge hiding with individual task performance and the mediation role of individual creativity. It focuses on how employees\' knowledge-hiding behavior can influence their task performance and how individual creativity can alleviate the negative consequences of knowledge-hiding. Data was collected from 256 employees working in financing companies in Indonesia. Hypothesis testing was conducted using the Structural Equation Model - Partial Least Square (SEM-PLS) model. The findings showed that all indicators significantly represented the dimensions of evasive hiding, playing dumb, and rationalized hiding, which collectively constitutes knowledge hiding. Furthermore, the study confirmed that individual creativity served as a mediator in the relationship between knowledge hiding and individual task performance. The implications of this study underscore the importance of addressing knowledge-hiding behavior within organizations and promoting individual creativity as a means to overcome the negative consequences and enhance task performance.
