Employees’ innovative work behaviours (IWB) emphasize the multifaceted nature of employee contributions to organizational innovation, encompassing both the ideation stage and the necessary implementation behaviours that translate innovative ideas into tangible performance improvements. Fostering a work environment that encourages and celebrates IWB becomes crucial for organizations seeking to maximize their innovation potential. This study delves into the intricate relationship between work environment, encompassing both its social and physical facets, and IWB. Building upon theoretical foundations in innovation, innovative behaviour, and work environment research, the article presents an analytical framework to unravel the influence of these factors. The proposed framework leverages an integrated approach by combining insights from Affective Events Theory (AET) and Expanded Person-Environment Fit (PEF) theory. This integrated lens posits that IWB are shaped by both the social and physical environment, mediated by innovation trust, with personal innovativeness acting as a moderator. This framework paves the way for further research in the fields of innovation management.
