The National Amalgamated Coal Workers' Union was a trade union in the United Kingdom which existed between 1889 and 1922.
It represented coal porters and carmen.
[1] A major three-week strike occurred in London in 1892, involving 6,000 members of the union, over the employment on a non-union worker and the failure of some employers to pay standard wages.
The strike was unsuccessful, but it was agreed through conciliation that the strikers would be re-employed.
[2] Following the failure of the strike, the union affiliated to the Miners' Federation of Great Britain, but its membership fell, to 4,000 in 1896 and 1,535 in 1910.
