| An industrial society, especially one
as centralized and concentrated as that of Britain, is heavily dependent on
certain essential services: for instance, electricity supply, water, rail and
road transport, the harbours. The area of dependency has widened to include
removing rubbish, hospital and ambulance services, and, as the economy develops,
central computer and information services as well. If any of these services
ceases to operate, the whole economic system is in danger. It is this interdependency of the economic system which makes the power of trade unions such an important issue. Single trade unions have the ability to cut off many countries’ economic blood supply. This can happen more easily in Britain than in some other countries, in part because the labour force is highly organized. About 55 per cent of British workers belong to A. (A) Some industries have no unions. B. (B) Unions are not organized according to industries. C. (C) Only 55 per cent of workers belong to unions. D. (D) Some unions are too powerful.
