When someone refers to religious or belief discrimination, they actually refer to ‘the differential treatment of individuals or groups based on their system of belief or worship’ (Eurofound, 2019).
Religious discrimination can be either direct or indirect. Cases of employees that were prohibited to wear religious symbols (e.g., hijab, headscarf, crucifix, turban) at their workplace by their employers have reach the Court of Justice of the European Union and the European Court of Human Rights and decisions were taken on a case-by-case basis.
Associated with the above, is the term religious Intolerance, which refers to the refusal by a group or community to tolerate diversity on the basis of religious beliefs.
