JD Sports is to launch an investigation into conditions at its Kingsway warehouse near Rochdale after a Channel 4 documentary found workers claiming it was “worse than a prison”...there were harsh practices at the warehouse, including a “three strikes and you’re out” policy, intense surveillance and heightened job insecurity among agency workers..One worker said in the film: “It’s more worse than a prison. Prisons get more frigging respect.”JD Sports denied the claims...Iain Wright MP, chair of the Commons business, energy and industrial energy committee, said workers were “treated like scum”. He said the alleged three-strikes policy was “twice as bad as what we found at Sports Direct”. TUC general secretary Frances O’Grady said it was “increasingly clear that Sports Direct wasn’t just one bad apple, and that terrible working practices are taking place across the UK.“The government needs to look seriously at how this sort of behaviour continues to take place in today’s Britain.”
