Organizations are increasingly adopting new technologies, such as social media, that afford employees a repertoire of uses not simply focused on work, but also on socialization and entertainment. Knowledge regarding the impact of such diverse technologies on job performance, however, is currently limited. This study adopts a technology use lens to study the effect of three categories of social media use social, hedonic, and cognitive on job performance, as mediated by three dimensions of social capital. The research was conducted via a large-scale survey within a multinational Information Technology company. Social and cognitive uses of technology were empirically shown to have a positive, albeit indirect, effect on employees' routine and innovative job performance. Hedonic use of the technology, while having a direct negative impact on routine performance was shown to positively contribute to the development of social ties, leading to a mitigating positive influence on innovative performance. This interesting positive side of hedonic use, along with all findings from our study, are discussed and used to offer insights to future research and practice. (C) 2015 Elsevier B.V.
