The law relating to freedom of speech has grown faster than any other area of employment law over the past decade. Press controversies over online speech, disputed claims to the Equality Act, and allegations of no-platforming have all had the effect of making this the most dynamic area of workplace law. This book provides an introduction to this changing area of law in Great Britain. The first part of the book explains the overarching principle of employment and free speech law; the second half provides detailed case studies in relation to the specific examples that most commonly come before the courts. The book will be an essential reference for students, academics, and professionals working in the areas of Employment Law, Human Rights Law, and Contract Law. The British example will be of interest to an international readership.
