The impact of social and work-related social media usage on job performance

This study aims to analyze the impact of social and work-related social media usage on job performance, both directly and indirectly, mediated by knowledge sharing and job satisfaction. The research employs a quantitative method, with respondents comprising lecturers from private universities in Malang City, Indonesia. The sample size, determined using Slovin's formula, consists of 351 respondents. Data collection was conducted through questionnaires, and the relationships between variables were analyzed using PLS with the SmartPLS application. The hypothesis analysis results indicate that social-related social media usage does not affect knowledge sharing but positively influences job satisfaction and job performance. Work-related social media usage has a significant positive relationship with knowledge sharing, job satisfaction, and job performance. Knowledge sharing cannot mediate the relationship between social-related social media usage and job performance. However, job satisfaction can mediate the relationship between these variables. Knowledge sharing and job satisfaction significantly positively mediate the relationship between work-related social media usage and job performance. The results of this study provide insights for higher education leaders regarding the management of social media in higher education institutions, emphasizing both social and work-related social media usage. Both have different impacts, especially on knowledge sharing. Policies to restrict social-related social media usage during work hours are necessary because informal communication can disrupt concentration during work, communication overload can also occur due to excessive unplanned communication, and echo chambers can result in minority lecturers engaging more in knowledge hiding.
