This book, first published in 1973, sets out the reason why workers' control is the necessary alternative to the present system. It describes the struggle of the workers through their organizations to achieve a greater control over their lives; and it discusses the practical steps which need to be taken to achieve complete workers' control. Practicality is the keynote of this book, which starts from the reality of the 1970's and progresses towards the essence of socialism - workers' control.
