The paper demonstrates its ‘CSR at a tipping point’ thesis by juxtaposing views of corporate social responsibility (CSR) as essential for business and societal sustainability against those that see CSR as unaffordable or irrelevant in the current economic climate. Drawing from Kohlberg's seminal theory of moral development, CSR is conceptualised as the development of organisation moral reasoning, and the proposition is illustrated by demonstrating inter-disciplinary similarities in levels of ethical concern within different approaches to the practice of marketing, human resource (...) management (HRM) and performance management. Levels of concern for CSR are related to environmental and firm-specific drivers and constraints that influence the CSR dynamic. Environmental influences on organisational CSR stances emanate from a range of stakeholder constituencies, while the importance accorded to CSR is also influenced by firm-specific factors such as the organisation's stage of development, strategy and leadership. The paper's identification of inter-disciplinary similarities in the varying levels of concern for CSR and its delineation of CSR drivers and constraints contribute to CSR theory, and these frameworks also represent analytical tools that managers can use to assess or to change an organisation's CSR stance. The multi-level perspective on CSR adopted by the paper links an organisation's overall or ‘macro’ CSR stance to the ‘meso’ levels of CSR represented by practice within its specialist functions. It proposes that the ‘CSR at a tipping point’ proposition is assessed by utilising the conceptual model in the paper within a case-study research design to determine whether specific organisations – identified as ‘CSR-positive’ ones by their relatively high level of concern for stakeholder welfare – are changing the importance they accord to CSR as a result of the new business context, and the extent to which practice in their marketing, HRM and performance management functions are shapers or consequences of this.
