Labour's concern over automation arises from uncertainty about the effects on employment, and fears of major changes in jobs. In the main, labour has taken the view that resistance to technical change is unfruitful. Eventually, the result of automation may well be an increase in employment, since it is expected that vast industries will grow up around manufacturing, maintaining, and repairing automation equipment. The interest of labour lies in bringing about the transition with a minimum of inconvenience and distress to the workers involved. Also, union spokesmen emphasize that the benefit of the increased production and lower costs made possible by automation should be shared by workers in the form of higher wages, more leisure, and improved living standards.
concern [U]: (concern over/for/about sth./sb.) worry, anxiety
