Inequality at work and in work still is one of the cruelest and most glaring forms of inequality in our society. We can not hope to solve the more obvious problems of industrial life, many of which arise directly or indirectly from the inequality at work. Still less can we hope to create a decent and humane society.
The most glaring inequality is that between managers and the rest. For most managers, work is an opportunity and a challenge. Their jobs engage their interest and allow them to develop their abilities. They are able to exercise responsibility; they have a considerable degree of control over their own and the others' working lives. Most important of all, they have the opportunity to initiate. By contrast, for most manual workers, work is a boring, monotonous, even painful experience. They spend all their working lives in conditions which would be regarded as intolerable for themselves by those who take the decisions which let such conditions continue. The majority have little control over their work; it provides them with no opportunity for personal development. Often production is so designed that workers are simple part of the technology. In offices, many jobs are so routine that workers justifiably feel themselves to be mere cogs in the bureaucratic machine. As a direct consequence of their work experience, many workers feel alienated from their work and their firm, whether it is in public or in private ownership.
