Abstract
The purpose of this study was to explore the relationship between employee engagement and organizational citizenship behaviour (OCB) in Thailand. The influence of employee perceptions of human resource development (HRD) practices as potential moderators were also examined. Data were collected from 522 employees from four large Thai organizations. The results found support for positive relationships between employee engagement and every component of OCB. The relationship was found to be strongest for the civic virtue component of OCB. However, no support was found for the hypothesized moderating effect of HRD practices between employee engagement and OCB. Discussion and recommendations for future research and practice are also provided.
