This paper presents an emerging theory of coaching as a Generative Scaffold which can support managers experiencing stress at work. This conceptualises a process in which the coach supports the manager to generate insights, strength, and action, in order to improve their situation. Developed using Constructivist Grounded Theory, my findings suggest that common coaching approaches might be missing vital ingredients if they are to be effective in supporting managers in this context. Underpinned by critical inquiry, the study raises important ethical questions for coaches working within organisations and it makes a case for coaches as agents of social change.
