As organizations recognize the need to engage in CSR and sustainability initiatives, it is integral to success to communicate that they are doing so. However, the research focus is more often on communicating with external stakeholders to draw attention to corporate responsibility initiatives. Internal stakeholders as employees are not researched as often, despite their integral role in communicating the organization's CSR vision and sustainability as they interact with external stakeholders. In order to explore employee perceptions of CSR communication, a two‐phase mixed‐method study was undertaken, including semi‐structured interviews with 20 CSR managers in NZ organizations to provide content to inform an online questionnaire survey to seek feedback from employees in these same organizations. This paper contributes to research on internal stakeholders in revealing the influence of the perceived value congruence between managers and employees in influencing internal stakeholder perceptions of CSR and sustainability initiatives. The findings have implications for public policy, enhancing organizational communication, the need for authenticity and managerial recognition of their role in facilitating employee commitment to CSR initiatives.
