The London Dock strike was an industrial dispute involving dock workers in the Port of London. It broke out on 14 August 1889, and resulted in a victory for the 100,000 strikers and established strong trade unions amongst London dockers, one of which became the nationally important Dock, Wharf, Riverside and General Labourers' Union. The strike is widely considered a milestone in the development of the British labour movement, symbolising the growth of the New Unions of casual, unskilled and poorly paid workers, in contrast to the craft unions already in existence. The strike helped to draw attention to the problem of poverty in Victorian Britain and the dockers' cause attracted considerable public sympathy.
Sing a song of sixpence,
Dockers on the strike.
Guinea pigs are hungry,
As the greedy pike.
Till the docks are opened,
Burns for you will speak.
Courage lads, and you'll win,
Well within the week.
Colonel G. R. Birt, the general manager at the Millwall Docks, gave evidence to a Parliamentary committee, on the physical condition of the workers:
The poor fellows are miserably clad, scarcely with a boot on their foot, in a most miserable state ... These are men who come to work in our docks who come on without having a bit of food in their stomachs, perhaps since the previous day; they have worked for an hour and have earned 5d.; their hunger will not allow them to continue: they take the 5d. in order that they may get food, perhaps the first food they have had for twenty-four hours.
Prior to the strike, few dockers were organised, but once it began, the Dock, Wharf, Riverside and General Labourers' Union recruited a substantial section of the London docks workforce. The principal demand of the agitation was for the dockers' tanner, meaning a rate of sixpence an hour. The strike was noted for large, peaceful processions which impressed middle class opinion and won sympathy for the strikers' cause from figures such as Cardinal Manning, who acted as meditator between the striking workers and the dock owners. He was seen as fair and impartial by both sides. Upon the resolution of the strike, the dock workers collected £160 for Manning in appreciation of his work, and Manning donated the money to a local hospital to provide a bed.
