My former PhD supervisor and I were recently discussing the role of a 'companion' as a promising metaphor. A companion is someone with you on your journey with whom to share the experience, a witness of your encounters and reflections. Research is often a solitary journey on which postgraduate students would certainly appreciate such company, if student feedback on their experience is anything to go by. Researching diversity is a demanding endeavour: it spans deeply personal issues of identity as well as pressing social issues of equality and change. In this context relatability for students is as important as the need to be relevant by solving diversity issues in the workplace. The quality of a companion should therefore include such criteria: does it provide compelling conversations on diversity discourse and does it speak about research practice in ways which students find useful. In this sense Just, Risberg, and Villasèche's (2021) collection The Routledge Companion to Organizational Diversity Research Methods is an enriching and thought-provoking companion.The collection opens with the need to problematise the purpose behind diversity research.We are made aware of the different approaches to understanding and improving diversity practices developing over time: defining categories of diversity, who gets to write the narratives of diversity experience through privileged positions, diversity management as an organisational asset, fluidity of identity and bias with a focus on individualised experiences etc. These raise important questions for research students, a much-needed opportunity to Mariana Bogdanor, Book review: The Routledge Companion to Organizational Diversity Research Methods, Management Learning, 0 (0) pp. 1-4.
