The Community Charter of the Fundamental Social Rights of Workers, commonly known as the Social Charter, was adopted in 1989. While the United Kingdom did not subscribe to the charter, it must be emphasised that the charter itself — a "solemn declaration" by the European Council — is not part of any of the treaties governing the European Union. It simply laid down a set of non-binding principles on which laws might be based. An action programme based on those principles was drawn up by the European Commission and the legislative proposals contained therein (e.g., the Directive on Working Time) were based on Treaty provisions to which all member states, including the UK, were subject.
