The United Kingdom Society of Amalgamated Smiths and Strikers was a trade union representing foundry workers in the United Kingdom.
[1] In 1886, the union was refounded as the "United Kingdom Society of Amalgamated Smiths and Strikers".
It grew quickly, and became the main rival of the Associated Blacksmiths', Forge and Smithy Workers' Society, particularly in railshops.
[2] By the following year, it had 2,200 members,[2] and membership reached 4,347 in 1899, at which point it was the largest union in the industry.
During the 1910, the union undertook lengthy but unsuccessful negotiations about a possible merger with the Associated Blacksmiths.
