[37:39.76]A good example of the division of labor is an assembly line in an automobile factory.
[37:46.31]One worker may install a door while another is installing the hood.
[37:51.82]The others add lights, windshield wipers, and so on. Normally, workers stay in one place,
[37:59.23]and a conveyor belt moves the product to them. If one worker had the responsibility of producing an entire car,
[38:08.59]he or she might be able to complete one each year.
[38:12.80]By comparison, factories with assembly lines may produce an average of about thirty-five cars a year perworker.
[38:20.98]The division of labor permits mass production, but it does have some disadvantages.
[38:27.60]For one thing, few people know or understand all aspects of an operation.
[38:33.79]In addition, mass production may be more efficient, but many workers complain that they get little job satisfaction from working on one small duty,
[38:44.05]day after day. To them, there is much more satisfaction in doing a job from start to finish.  (202 words)
