A strike of long duration, involving large numbers of workers, over a fundamental issue that is central to the interests of both union and employer. Trials of strength can be bitter and occasionally violent events because a great deal may be at stake. An example is the long strike in the British mining industry in 1984–5 over management's right to close loss-making collieries. Trials of strength can be key turning points in the evolution of industrial relations and after the miners' strike, for instance, there was an extensive restructuring of the mining industry that resulted ultimately in privatization, extensive closure, and the effective derecognition of the National Union of Mineworkers.
