The National Council of Trade Unions (NCTU) is an umbrella organization that represents various trade unions in a country. Its primary role is to advocate for workers' rights, improve labor conditions, and promote fair wages. The NCTU works to unify different unions to strengthen their collective bargaining power and influence in negotiations with employers and the government. Additionally, the NCTU engages in policy discussions and lobbying efforts to address labor-related issues at the national level. It often collaborates with other organizations, such as international labor organizations, to align its goals with global labor standards and practices.
