E-learning has been widely used as a prominent solution to provide on demand learning opportunities to reduce training time and cost. While e-learning acceptance has received a significant attention in academic/student domain, little research has been conducted in organizational setting. This paper aims to contribute to understanding the underlying factors which influence employees' intention towards using e-learning systems, through developing and proposing a conceptual research model based on one of the most comprehensive behavioral theory, the Unified Theory of Acceptance and Use of Technology (UTAUT). The proposed conceptual model first examines the native UTAUT constructs and then, by borrowing insight from other theories in the literature, expands the UTAUT theory to account for more context-specific e-learning factors in a workplace setting, namely, perceived organizational support, e-learning self-efficacy, perceived e-learning content quality and e-learning satisfaction. The paper also identifies directions for an empirical examination of the proposed research model in future.
