This study proposes a research model based on attachment theory, which examines the role of corporate citizenship in the formation of organizational trust and work engagement. In the model, work engagement is directly influenced by four dimensions of perceived corporate citizenship, including economic, legal, ethical, and discretionary citizenship, while work engagement is also indirectly affected by perceived corporate citizenship through the mediation of organizational trust. Empirical testing using a survey of personnel from 12 large firms confirms most of our hypothesized (...) effects. Finally, theoretical and managerial implications of our findings are discussed.
