Sheffield's early success in steel production had involved long working hours, in desperately unpleasant conditions which offered little or no safety protection. In The Condition of the Working Class in England in 1844, Friedrich Engles quotes a local doctor, Dr. Knight, regarding the so-called "Grinder's Asthma" suffered by the Sheffield cutlery workers in the mid 19th. century:
They usually begin their work in the fourteenth year, and if they have good constitutions, rarely notice any symptoms before the twentieth year. Then the symptoms of their peculiar disease appear. They suffer from shortness of breath at the slightest effort in going up hill or up stairs, they habitually raise the shoulders to relieve the permanent and increasing want of breath; they bend forward, and seem, in general, to feel most comfortable in the crouching position in which they work. Their complexion becomes dirty yellow, their features express anxiety, they complain of pressure on the chest. Their voices become rough and hoarse, they cough loudly, and the sound is as if air were driven through a wooden tube.
By the mid-late 1860s the majority of the objectives of the Chartist movement had been frustrated. These social and political reformers had not accomplished all they had hoped to, although they had succeeded in lobbying for the establishment of the first town council in 1843. (Eventually, the great majority of the items of their 'charter' did, in fact, become law).
Social and working conditions in industrial England were not showing any significant improvement and the - as yet unrecognised - trade unions struggled to protect the interests of their members. These conditions provoked great discontent and eventually militant action. In some isolated incidents, workmen even began to use violence to punish employers and also those fellow-workers who would not become union members: the so-called "Sheffield Outrages".
The trade unions themselves sought a formal inquiry to establish the facts of the matter, largely as a result of accusations in the newspapers of complicity in these outrages resulting from investigations by W. C. Leng of the Sheffield Daily Telegraph. On November 17. 1866 a delegation, which included members of the Sheffield Trades Council and the London Trades Council, requested that the Home Secretary take the necessary measures to investigate.
This led to a Special Commission of Enquiry into these occurrences in May 1867. Immunity was offered to all who gave evidence and, as a result a number of people were encouraged to testify. Among these was William Broadhead, the Secretary of the Sawgrinders' Union at that time, who described how he had paid two workmen £5 to murder a man called Linley who had taken on too many apprentices, which was, in practice, a method of acquiring cheap labour.
