Henry R. King (c. 1826 – 18 October 1903) was a British trade union leader.
Dunning suffered an accident in 1871, and as a result, King was in his place appointed as secretary to a joint committee campaigning for a maximum nine hour working day.
[1] By 1873, Dunning's health had not improved, and he had to resign as secretary of the London Consolidated Society.
His support of women's trade unionism was not shared by everyone in the movement, and led to a major dispute in 1883, when the London Consolidated Society ignored requests from the Dublin branch of the Consolidated Union for support in a strike opposing the employment of women bookbinders in the city.
A committee of the Trades Union Congress was assembled, and the London Consolidated Society was required to pay some costs of the Dublin branch.
