This factsheet examines the importance of freedom of religion in the workplace as one of the foundations of a democratic society. Jointly published by FRA and the European Court of Human Rights, it examines relevant EU law on the topic, and explains how courts handle issues where EU law and human rights law overlap. It highlights key court decisions from the Court of Justice of the European Union (CJEU) and the European Court of Human Rights (ECtHR) to show how these two legal systems work together on aspects of religious freedom in the workplace, such as wearing religious symbols to work and time off for religious holidays.
