The National Transport Workers' Federation (NTWF) was an association of British trade unions.
It was formed in 1910 to co-ordinate the activities of various organisations catering for dockers, seamen, tramwaymen and road transport workers.
One of its members William Ball, was the subject of a pamphlet 'Torture in an English Prison' about his treatment as a male union supporter of women's right to vote in 1911.
[1] In 1912, it called a National Dock Strike in support of London dockers which was observed only in a few centres, and which ended within a week.
This was regarded as an embarrassing setback, and led the Federation to adopt a more cautious approach in subsequent years.
