Can work be a source of meaning without turning business into religion?Spirituality shapes how people think about purpose, goodness, connection, and the lives they build through work. Yet workplace spirituality is often vague, sentimental, or detached from evidence.The Spirituality of Work & Leadership takes a more demanding route. Paul Gibbons examines what spirituality means across religious, mystical, humanist, and secular traditions-and asks what those traditions can contribute to work and leadership in pluralistic organisations.Inside the book how spirituality differs from religion, and where science belongs the history of work, vocation, and the search for meaningful work what research says about mindfulness, flow, happiness, and flourishing how purpose can guide a life or organisation without becoming corporate theatre why spiritual leadership requires service, moral development, systems thinking, and responsibility for the whole how leaders can support meaning and connection without acting as priests or gurus Drawing on philosophy, psychology, neuroscience, evolutionary biology, sociology, religious traditions, and decades of business experience, Gibbons combines scholarship with practical judgement. He is as interested in the limits of workplace spirituality as in its promise.This is Volume I of the Humanizing Business series. It is written for leaders, change practitioners, scholars, spiritual readers, and sceptics who want a rigorous account of meaning, purpose, and humanity at work.
