Gratton was born in Liverpool, England, and obtained a BA and a PhD at Liverpool University. She is Professor of Management Practice at London Business School and is the founder of the Hot Spots movement, which exchanges management ideas around the world of business, including some of the world's biggest companies.
Her book, also called Hot Spots (2007), is focussed on bringing innovation and energy into organisations, such as "Why some teams, workplaces and organisations buzz with energy – and others don't".
Gratton is rapidly adding to her credentials with awards, appointments and recognition, and in 2011 The Times ranked her in the top 15 of the world's leading management thinkers. The Financial Times in 2008 regarded her as the business thinker most likely to make a real difference in the next decade.
Her HBR paper The End of the Middle Manager contentiously raises a very important issue by postulating that middle management has disappeared.
