Over the last two decades, scholarly research on professional service firms (PSFs) has grown into a significant body of knowledge and indeed a distinct subfield of management studies. In this essay, we offer a postcolonial critique of this subfield. We show that it is built almost exclusively on studies conducted in the West (mainly North America, Scandinavia and the UK), and yet presents its theorising as though it were universal. This is despite PSF scholars generally being distinctly sensitive to (organizational) difference and having no steadfast commitment to positivism. Importantly, we also show that PSF scholarship tends to construct Western professionals as a normative referent whilst glossing over their role in neo-colonialism. What started as a productive effort to research an unusual – ‘professional’ and ‘knowledge-intensive’ – type of organization (in the West) has, in effect, inadvertently evolved into a geopolitically inflected scholarly domain. We urge PSF scholars to recognize and interrogate the problem and work to address it in their own research – and we offer suggestions to that end. Our analysis also has implications for the postcolonial critique in management studies more broadly.
