More information

  • For anyone who wants to learn more about the 1972 building workers’ strike and subsequent Shrewsbury trials, we recommend you read The Key to My Cell by Des Warren. You can get a copy of his book from the News From Nowhere Radical and Community Bookshop. Warren was a building worker activist who, along with Ricky, was framed during the events at Shrewsbury and sentenced to three years in prison.
  • Free the Six – Film made by film students Michael Rosen and Jeff Perks in 1974. It shows the lack of health and safety on building sites and also gives a voice to building workers who took part in the strike giving a  honest and clear accounts of how they organised flying pickets.
  • Our guest, Tony O’Brien, has also recently written the book Tackling the Housing Crisis: the Case for Council Housing and Directly Employed Construction Workers. Tony argues that housing is a human right and shows how the creation of a national public-sector construction organisation can fix our corrupt system controlled by building companies and property speculators.

In the the above picture of the final site meeting at Brookside is a building worker called Clifford Growcott (bottom right-hand corner, back to camera). Growcott featured heavily in media coverage of the strike and subsequent Shrewsbury trials as ‘proof’ of violent picketing: in interviews, Growcott claimed to have been “punched and kicked like a football” and lost all sight in his right eye. However, as can clearly be seen above, Growcott is standing during the meeting unharmed (during the trial, as was pointed out by Arthur Murray, a building worker and friend of Ricky Tomlinson, photos from the day were presented in the wrong order so that this meeting was presented as happening first rather than last).

Des Warren’s counsel, John Platts-Mills, brought the attention of the judge to the fact that Growcott’s claims in the Daily Mail go “beyond anything he ever said here”. Years later, the media’s accusations of violence would grow more outlandish: when Ricky appeared on television in 1981, the Mail ran the headline ‘I was a victim of the picket who played TV hero’ claiming that Growcott was attacked by “a column of 80 pickets [who] pulled him off a ladder, kicked him to the ground and smashed his head in with a brick.” Readers can judge from the above picture as to whether that seems to have been the case.
