Organizations have increasingly recognized that employee innovation-defined as the intentional generation, promotion, and implementation of new and useful ideas aimed at benefiting role performance, the group, or the organization (West & Farr, 1990)-is a critical resource for ensuring effectiveness, growth, and continuous development in rapidly changing and uncertain environments (Hammond, Neff, Farr, Schwall, & Zhao, 2011). Employee innovation entails in-role and extra-role components (Poto nik & Anderson, 2016) because it can either be part of the prescribed work tasks or go beyond formal role descriptions (West, 2002). Considering the significance of employee innovation, a vast body of research has identified a range of affective and motivational drivers that can have energizing effects on employees' engagement in innovative endeavors, such as positive affect, intrinsic motivation, job satisfaction, and psychological empowerment (for a recent review, see Anderson, Poto nik, & Zhou, 2014). Theories and research on organizational commitment have emphasized affective commitment as a critical motivational force binding individuals to effective courses of action that sustain the organization and its goals (Meyer & Herscovitch, 2001; Solinger, Van Olffen, & Roe, 2008). However, prior empirical research has yielded contradictory findings on the relationship between affective commitment and employee innovation (Vinarski-Peretz, Binyamin, & Carmeli, 2011), with some studies finding positive effects and others reporting non-significant effects (e.g., Thompson & Heron, 2006). These premises thus underscore the importance of further research to illuminate how organizations can ensure that highly committed employees are motivated and enabled to perform innovatively in the workplace. To address this issue, our study aims to test a multilevel moderation model in which participative leadership acts as a key team-level h t t p s : / / j o u r n a l s. c o p m a d r i d. o rg / j wo p
