Stockport Card, Blowing and Ring Room Operatives' Association was a trade union representing cotton industry workers in the Stockport area of Cheshire in England. The union was founded in 1859, shortly after the Bolton Cardroom Association, the two being the oldest unions of cardroom workers to endure. In its early years, the union organised only strippers and grinders, and was only open to men. This caused problems in 1867 when women workers, who were not permitted to join the union, agreed to accept a 5 per cent cut in wages. As a result, the union lost a strike against a 10 per cent cut in its own members' wages.
