Research on Corporate Social Responsibility (CSR) has developed tremendously over the past four decades, especially regarding affective organizational commitment, organizational behavior, and many other variables. However, research on how employee perception on organizational CSR activities and how it relates to job performance are still scant in nature. This study aims to answer these gaps. This study uses quantitative approach using Social Exchange Theory as the underlying argument. Purposive sampling is used in this study with aim on Greater Jakarta area (Jabodetabek), and the questionnaire was distributed using WhatsApp application. As many as 105 respondents returned the distributed questionnaire, in which only 93 is deemed to be worthy of further analyses. Four variables are used to be the focus of this study, namely Employee perception on CSR, Job Performance, Employee Engagement and Job Satisfaction.

While Job Satisfaction did not mediate the relationship between Employee perceived CSR towards Job Performance.  This study manage to provide contribution in the literature of CSR especially in the perspective of Employee perception on CSR and in the context of developing countries.
