Abstract
Purpose: The purpose was to investigate the effect of excessive use of social media in the workplace on employees' job performance.
Methodology: This study is an applied research. Population includes all government employees through Nov. 2020 to April 2021. A 19-item questionnaire was used to collect and assess the current situation. Validity and reliability was confirmed. Structural equations have been used to investigate the relationships between the components of the model. LISREL software was used to examine the hypotheses.
Findings: Findings have shown that excessive social use (rendering t-statistic of 4.24) and excessive cognitive use of social media in the workplace (according to t-statistic of 2.92 ) have a positive relationship with media fatigue, but hedonistic use has no effect on social media fatigue. Social media fatigue also has a positive relationship with employees' job performance (Based on t-statistic of 7.13). Also, according to z statistic (2.70) social media fatigue plays a mediating role in the relationship between excessive cognitive use of social media in the workplace and employees' job performance. Further, social media fatigue has a mediating role (giving z statistic of 3.64) in the relationship between excessive social use of social media in the workplace and employees' job performance. But social media fatigue does not mediate the effect of hedonistic use on employees' job performance.
Conclusion: Conferring unnecessary use of social media includes three dimensions. The role of these dimensions in influencing fatigue and job performance was examined and it was found that each of these dimensions has a different effect on fatigue and job performance. Therefore, this issue helps to theoretically understand the relationship between excessive use of social media and job performance, as well as for managers to formulate policies related to t

Abstract
Background and purpose: The Health Ministry plays a fundamental role in providing primary and to some extent secondary services in the Iranian health system, and the employees in the health ministry have important and dangerous tasks in order to maintain and promote the health of the community. Since improving the performance of health assistants can ultimately lead to improving health indicators, the main objective of the project is to study the role of pessimism in the professional performance of health assistants at the University of Medical Sciences in Isfahan, given the role of knowledge mediation and moderation of managerial leadership.
Materials and methods: This research is descriptive , experimental in functional purpose, and methodological in data collection. The statistical community of the study consisted of 235 staff members of the health department, who were considered on the basis of a sample number table of 140 people, but the 200 questionnaires were distributed in a simple random manner. The data were collected in a library-like and field-like manner. Standard questionnaires on job cynicism, knowledge retention, job performance scale, and transformational leadership were used to measure the research variables. Structural equation modeling with the PLS software was used to analyze the data..
Findings: Pessimism with a coefficient of 322/-0 has a significant and adverse effect on the professional performance of employees of the Health Department of the University of Medical Sciences in Isfahan. Pessimism with a coefficient of 486/0 has a significant effect on concealing the knowledge of the staff of the Health Department of the University of Medical Sciences in Isfahan.
Conclusion: In the organization, it is necessary to create an environment that encourages positive attitudes and encourages positive behaviors among employees. To reduce pessimism, it can be effective to involve more employees in decision-making and to encourage and support employees to come up with creative ideas to improve work processes.
