Reveals the class markers that operate within the world’s most powerful firms and outlines the practical steps for leading employers to dismantle class barriers.
Class, so the narrative goes, has been banished to the past in our modern meritocratic world. Yet across the world’s major economies, entry to the elite remains governed by a set of unwritten and largely invisible workplace class codes: rules encompassing ways of speaking and social etiquette, hidden cultural norms, and the confidence to advocate for yourself in highly competitive environments — codes passed down through generations.
In this groundbreaking global study, Lee Elliot Major and Anne-Marie Sim lay bare the class markers that operate within the world’s most powerful firms, revealing how they connect to a wider class system structured around a small, detached elite and everyone else. They outline ten practical steps for leading employers to dismantle class barriers and make the urgent case for a fairer system in which everyone has a genuine chance to lead a decent life, whatever path they choose.
Lee Elliot Major is Britain’s first Professor of Social Mobility, based at the University of Exeter. He was previously Chief Executive of the Sutton Trust, the UK’s leading social mobility foundation. A leading voice in national and international education debates, he advises corporate, government and education leaders across the globe. His award-winning books include Equity in Education and Social Mobility and Its Enemies. He is a Fellow of the Academy of Social Sciences and was awarded an OBE in the 2019 Queen’s Honours.
Anne-Marie Sim is co-founder and lead of the South-West Social Mobility Commission at the University of Exeter. She was previously a strategy consultant with the Boston Consulting Group, where she worked with leading UK and global companies. She holds a DPhil and Masters in anthropology and Bachelors in Economics and Management from the University of Oxford.
