Social media is all about awareness and connection, and presently the social media seems to be the tool that affects the job performance of the employee in the workplace. The new media is growing so fast that it makes it imperative for employees to embrace the medium. The purpose of the study is to investigate the effects of social media usage on employee job performance. The study is limited to the effects of social media usage on employee job performance among employees in one of the biggest and successful publishers in Malaysia.

The study used IBM SPSS Statistics Version 21 to analyse the data. Survey data were collected from 305 respondents through the simple random sampling technique. It was discovered that the use of social media at work helped employees to improve their performance. Thus, organizations should comprehend about social media while setting appropriate policies at the workplace.
