The National Union of Mineworkers (NUM) is a trade union in the United Kingdom that represents workers in the mining industry. Founded in 1944, it aims to protect the rights and interests of its members, advocating for better working conditions, wages, and job security. The union has played a significant role in the history of labor movements in the UK, particularly during the coal miners' strikes in the 1980s. NUM is affiliated with the Trades Union Congress (TUC) and has been involved in various campaigns to support miners and their families. The union also engages in political activities to influence policies affecting the mining sector and workers' rights. Through collective bargaining and solidarity, NUM seeks to empower its members and ensure their voices are heard.
