The Union of Democratic Mineworkers (UDM) was a British trade union for coal miners based in Nottinghamshire, England, established in 1985, [1] following the 1984–85 miners' strike, when the Nottinghamshire Area of the National Union of Mineworkers (NUM) was involved in a number of disputes with the National Executive Committee that led to a split from the NUM. In ballots on joining with Nottinghamshire in a new union, the South Derbyshire Area of the NUM voted in favour by 51% and the Colliery Workers and Allied Trades Association by almost 100%. [4]
The Nottinghamshire Miners' Association initially remained within the National Union of Mineworkers with elected officers including Roy Lynk and Neil Greatrex, later the General Secretary of the UDM. Officials from the UDM advised ministers on how to cut miners' power – including by weakening the National Association of Colliery Overmen, Deputies and Shotfirers (NACODS). [5]
For many NUM supporters and Arthur Scargill loyalists, the UDM was and remains considered a "scab" union due their split for the NUM, return to work and cooperation with the Thatcher government. [6]
The UDM was widely criticised in 2004 after it was revealed that its top two officials received pay and benefits of over £150,000 each, despite membership having fallen to 1,431. [7] In 2012, former president Neil Greatrex was found guilty of fraud from a miners' welfare fund. [8]
The 1984–1985 United Kingdom miners' strike was a major industrial action within the British coal industry in an attempt to prevent closures of pits that the government deemed "uneconomic" in the coal industry, which had been nationalised in 1947. It was led by Arthur Scargill of the National Union of Mineworkers (NUM) against the National Coal Board (NCB), a government agency. Opposition to the strike was led by the Conservative government of Prime Minister Margaret Thatcher, who wanted to reduce the power of the trade unions.

The National Union of Mineworkers (NUM) is a trade union for coal miners in Great Britain, formed in 1945 from the Miners' Federation of Great Britain (MFGB). The NUM took part in three national miners' strikes, in 1972, 1974 and 1984–85. Following the 1984–85 strike, and the subsequent closure of most of Britain's coal mines, it became a much smaller union. It had around 170,000 members when Arthur Scargill became leader in 1981, a figure which had fallen in 2023 to an active membership of 82.
A strikebreaker is a person who works despite an ongoing strike. Strikebreakers may be current employees, or new hires, who are hired after or during the strike to keep the organization running. In continuing to work, or taking jobs at a workplace under current strike, strikebreakers are said to "cross picket lines".

The Miners' Federation of Great Britain (MFGB) was established after a meeting of local mining trade unions in Newport, Wales in 1888. The federation was formed to represent and co-ordinate the affairs of local and regional miners' unions in England, Scotland and Wales whose associations remained largely autonomous. At its peak, the federation represented nearly one million workers. It was reorganised into the National Union of Mineworkers in 1945.
