In the Summer of 1972, there was a national building workers strike lasting 3 months to reduce the working week to 35 hours, for a base wage of £30 per week and to campaign for the decasualisation of the industry. 'Flying' pickets travelled to the numerous building sites in North Wales and Shropshire to make the strike more effective. In February 1973, 24 pickets were arrested and charged with conspiracy to intimidate, under the 1875 Conspiracy and Protection of Property Act, over events which had taken place in Shrewsbury the previous September. The trial opened in October 1973 and lasted 3 months. Six of the men were given prison sentences. Ricky Tomlinson was given 2 years imprisonment and was released on parole in July 1975. Des Warren received 3 years and was not released until August 1976 when he wrote this pamphlet demanding a public enquiry into the arrests and sentences.
