In recent years, the hotel industry has increasingly adopted social media, which play key roles in advertising, marketing, and promotions within the hotel industry. However, there has been relatively little empirical research on the relationship between using social media and job performance in hotel employees. This study aimed to examine the relationships between social media usage, social capital, and job performance of hotel employees in Iran. In order to achieve the aim of the research, data were collected from 270 employees of Espinas Hotel in Iran by a simple random sampling method. The hypotheses were tested using structural equation modeling and the results showed that social media usage by hotel employees has a positive effect on the formation of structural, relational, and cognitive social capital. Moreover, structural, relational, and cognitive social capital formed as a result of using social media has a positive effect on job performance. This study advanced the previous knowledge of social capital theory for employees interacting with coworkers through social media in organizations.

近年来，酒店业越来越多地采用社交媒体，社交媒体在酒店业的广告、营销和促销活动中发挥着关键作用。然而，关于酒店员工使用社交媒体与工作绩效之间关系的实证研究相对较少。本研究旨在研究伊朗酒店员工的社交媒体使用、社会资本和工作绩效之间的关系。为达到研究目的，采用简单随机抽样的方法从伊朗埃斯皮纳斯酒店的270名员工中收集数据。假设使用结构方程模型进行测试，结果表明酒店员工使用社交媒体对结构、关系和认知社会资本的形成有积极影响。此外，结构的、关系的、由于使用社交媒体而形成的认知社会资本对工作绩效有积极影响。本研究为员工在组织中通过社交媒体与同事互动提供了社会资本理论的先前知识。
