In Religion and belief in United Kingdom employment law, Frank Cranmer discusses the relationships between religion and employment in the wider context. It is a particularly complex area of law that touches on a wide variety of issues, ranging from the basic question, ‘exactly what constitutes a “religion” or “belief”?’ to ‘what kinds of religious dress do my employees have a right to wear to work?’ and ‘what religious standards – if any – can I, as an employer, demand of my employees?’. The purpose of the study is to provide an overview of some of the current issues and problems surrounding the law relating to employment by religious organisations and the manifestation of religion in the workplace. Because the complexity of the law means that individual outcomes in disputed cases are often depend heavily on the facts, it does so primarily by examining recent case-law.
