Introduction of robots into factories, while employment of human workers is being reduced, creates worry and fear. ( ① ) It is the responsibility of management to prevent or, at least, to ease these fears. ( ② ) For example, robots could be introduced only in new plants rather than replacing humans in existing assembly lines. ( ③ ) Workers should be included in the planning for new factories or the introduction of robots into existing plants, so they can participate in the process. ( ④ ) It may be that robots are needed to reduce manufacturing costs so that the company remains competitive, but planning for such cost reductions should be done jointly by labor and management. ( ⑤ ) Since robots are particularly good at highly repetitive simple motions, the replaced human workers should be moved to positions where judgment and decisions beyond the abilities of robots are required.
