How does leader's support for environment promote organizational citizenship behaviour for environment? A multi-theory perspective

Organizational citizenship behaviour for environment of employees is indispensable in realizing environmental sustainability goals of organizations. However, in the growing literature of employee green behaviour at work, scant attention has been paid on the impact of leader's specific support for environment, and the mechanisms through which it impacts organizational citizenship behaviour for environment. Drawing upon social exchange theory, self-determination theory and theory of normative conduct, we tested the impact of leader's support for environment, autonomous motivation for environment and perceived group's green climate on organizational citizenship behaviour for environment in an integrated model. The sample included 313 executive level employees of green implemented textile and apparel manufacturing factories in Sri Lanka. The results of structural equation modelling showed a direct positive impact of leader's support for environment on organizational citizenship behaviour for environment. Further, autonomous motivation for environment and perceived group's green climate were found to be partial mediators between leader's support for environment and organizational citizenship behaviour for environment. We discussed the theoretical implications for sustainability literature and the managerial implications for organizational practitioners in promoting organizational citizenship behaviour for environment.
