Question: When was the start of the jurisdiction that the European Trade Union Confederation applies to?

full_context: Document 1: European Union law: The principal Treaties that form the European Union began with common rules for coal and steel, and then atomic energy, but more complete and formal institutions were established through the Treaty of Rome 1957 and the Maastricht Treaty 1992 (now: TFEU). Minor amendments were made during the 1960s and 1970s. Major amending treaties were signed to complete the development of a single, internal market in the Single European Act 1986, to further the development of a more social Europe in the Treaty of Amsterdam 1997, and to make minor amendments to the relative power of member states in the EU institutions in the Treaty of Nice 2001 and the Treaty of Lisbon 2007. Since its establishment, more member states have joined through a series of accession treaties, from the UK, Ireland, Denmark and Norway in 1972 (though Norway did not end up joining), Greece in 1979, Spain and Portugal 1985, Austria, Finland, Norway and Sweden in 1994 (though again Norway failed to join, because of lack of support in the referendum), the Czech Republic, Cyprus, Estonia, Hungary, Latvia, Lithuania, Malta, Poland, Slovakia and Slovenia in 2004, Romania and Bulgaria in 2007 and Croatia in 2013. Greenland signed a Treaty in 1985 giving it a special status.
Document 2: European Union law: The Social Chapter is a chapter of the 1997 Treaty of Amsterdam covering social policy issues in European Union law. The basis for the Social Chapter was developed in 1989 by the "social partners" representatives, namely UNICE, the employers' confederation, the European Trade Union Confederation (ETUC) and CEEP, the European Centre of Public Enterprises. A toned down version was adopted as the Social Charter at the 1989 Strasbourg European Council. The Social Charter declares 30 general principles, including on fair remuneration of employment, health and safety at work, rights of disabled and elderly, the rights of workers, on vocational training and improvements of living conditions. The Social Charter became the basis for European Community legislation on these issues in 40 pieces of legislation.
Document 3: European Club Association: Formed on the dissolution of the G-14 group in January 2008, as from the 2017-19 membership cycle, the European Club Association represents 232 clubs, made up of 109 Ordinary Members and 123 Associated Members, with at least one from each of the 54 national associations. The precise number of Ordinary Member clubs from each member association will be established every two years at the end of the UEFA season on the basis of the UEFA ranking of its member associations according to the following principles:
Document 4: Treaties of the European Union: Two core functional treaties, the Treaty on European Union (originally signed in Maastricht in 1992) and the Treaty on the Functioning of the European Union (originally signed in Rome in 1957 as the Treaty establishing the European Economic Community), lay out how the EU operates, and there are a number of satellite treaties which are interconnected with them. The treaties have been repeatedly amended by other treaties over the 65 years since they were first signed. The consolidated version of the two core treaties is regularly published by the European Commission.
Document 5: Public-sector trade union: A public-sector trade union (or public-sector labor union) is a trade union which primarily represents the interests of employees within public sector or governmental organizations.
Document 6: European Economic and Social Committee: The European Economic and Social Committee (EESC) is a consultative body of the European Union (EU) established in 1958. It is an advisory assembly composed of "social partners", namely: employers (employers' organisations), employees (trade unions) and representatives of various other interests. Its seat, which it shares with the Committee of the Regions, is the Jacques Delors building on Belliardstraat / Rue Belliard 99 in Brussels. Once known by the acronym "EcoSoc", the body is now referred to as the "EESC", to avoid confusions with the United Nations ECOSOC.
Document 7: Great power: With continuing European integration, the European Union is increasingly being seen as a great power in its own right, with representation at the WTO and at G8 and G-20 summits. This is most notable in areas where the European Union has exclusive competence (i.e. economic affairs). It also reflects a non-traditional conception of Europe's world role as a global "civilian power", exercising collective influence in the functional spheres of trade and diplomacy, as an alternative to military dominance. The European Union is a supranational union and not a sovereign state, and has limited scope in the areas of foreign affairs and defence policy. These remain largely with the member states of the European Union, which include the three great powers of France, Germany and the United Kingdom (referred to as the "EU three").
Document 8: Santer Commission: The Santer Commission was the European Commission in office between 23 January 1995 and 15 March 1999. The administration was led by Jacques Santer (former Prime Minister of Luxembourg).
Document 9: Jules Maaten: Jules Maaten was elected as a member of the European Parliament in the European Elections of 10 June 1999, on the list of the Dutch Liberal Party VVD and he joined the Liberal Group in the Parliament. He sat on the Committee for the Environment, Public Health and Consumer Affairs and, from 2002, on the Foreign Affairs Committee. During the first part of the legislature he sat on Economic and Monetary Committee. He has done legislative work on such issues as the Tobacco Directive, the introduction of the euro currency, water quality, AIDS, completion of the EU's internal market in alcohol products, international banking fees, the European Central Bank, safety of children's toys, car exhaust emissions, food safety, and genetically modified organisms and human genetics, homeopathic and pharmaceutical products, Dutch prisoners in Thailand.
Document 10: Confédération générale du travail unitaire: The Confédération générale du travail unitaire, or CGTU (United General Confederation of Labor) was a trade union confederation in France that at first included anarcho-syndicalists and soon became aligned with the French Communist Party. It was founded in 1922 as a confederation of radical unions that had left the socialist-dominated General Confederation of Labour (CGT), and in 1936 merged back into the CGT.
Document 11: Trade unions in Europe: The European Trade Union Confederation was set up in 1973 to promote the interests of working people at the European level and to represent them in the European Union institutions. It is recognized by the European Union, the Council of Europe, and the European Free Trade Association as the only representative cross-sectoral trade union organization at the European level.
Document 12: European Economic Community: The European Economic Community (EEC) was a regional organisation which aimed to bring about economic integration among its member states. It was created by the Treaty of Rome of 1957. Upon the formation of the European Union (EU) in 1993, the EEC was incorporated and renamed as the European Community (EC). In 2009 the EC's institutions were absorbed into the EU's wider framework and the community ceased to exist.
Document 13: History of the European Union: On 1 November 1993, under the third Delors Commission, the Maastricht Treaty became effective, creating the European Union with its pillar system, including foreign and home affairs alongside the European Community. The 1994 European elections were held resulting in the Socialist group maintaining their position as the largest party in Parliament. The Council proposed Jacques Santer as Commission President but he was seen as a second choice candidate, undermining his position. Parliament narrowly approved Santer but his commission gained greater support, being approved by 416 votes to 103. Santer had to use his new powers under Maastricht to flex greater control over his choice of Commissioners. They took office on 23 January 1995.
Document 14: European Coal and Steel Community: The European Coal and Steel Community (ECSC) was an organisation of 6 European countries set up after World War II to regulate their industrial production under a centralised authority. It was formally established in 1951 by the Treaty of Paris, signed by Belgium, France, West Germany, Italy, the Netherlands and Luxembourg. The ECSC was the first international organisation to be based on the principles of supranationalism, and started the process of formal integration which ultimately led to the European Union.
Document 15: European Union law: The Social Charter was subsequently adopted in 1989 by 11 of the then 12 member states. The UK refused to sign the Social Charter and was exempt from the legislation covering Social Charter issues unless it agreed to be bound by the legislation. The UK subsequently was the only member state to veto the Social Charter being included as the "Social Chapter" of the 1992 Maastricht Treaty - instead, an Agreement on Social Policy was added as a protocol. Again, the UK was exempt from legislation arising from the protocol, unless it agreed to be bound by it. The protocol was to become known as "Social Chapter", despite not actually being a chapter of the Maastricht Treaty. To achieve aims of the Agreement on Social Policy the European Union was to "support and complement" the policies of member states. The aims of the Agreement on Social Policy are:
