The Union of Jute, Flax and Kindred Textile Operatives was a trade union representing workers in the textile trades in and around Dundee in Scotland. The union was founded after a major strike in the industry in Dundee. The strikers had no official union representation, as the Dundee and District Mill and Factory Operatives Union opposed the action. As a result, in 1906, Mary Macarthur and John Reed of Dundee Trades Council founded it as the Dundee and District Union of Jute and Flax Workers. On formation, it had 3,964 members, of whom two-thirds were women, rising to 5,000 by 1910.
