The study investigates a moderated mediation model in which organizational trust moderates the indirect effect of employee engagement on innovative work behavior through employee voice under flexible working conditions. A questionnaire-based survey was conducted on 428 managerial executives representing the Indian manufacturing sector. The analysis was carried out to estimate the significance of indirect effect using SOBEL macro and the bootstrapping approach. The findings revealed that the indirect effect of employee engagement on employee’s innovative work behavior through employee voice positively drives with higher levels of organizational trust. Additionally, it was also ascertained that employee voice and employee’s innovative work behavior were positively associated. The study suggests that employee’s innovative work behavior increases through employee engagement and employee voice when organizational trust is high. Implications and future directions are discussed in light of the findings.
