     In recent years many countries have been faced with the problem of how to make their workers more

productive. Some experts believe that the answer is to make jobs more varied. Do more varied jobs lead

to greater productivity? There is something to suggest that while variety certainly makes the worker's life

more enjoyable, it does not make him work harder. So variety is not important.

     Other experts feel that giving the worker freedom to do his job in his own way is important and there

is no doubt that this is true. The problem is that this kind of freedom cannot easily be given in the modern

factory with its complicated machinery which must be used in a fixed way. Thus while freedom of choice

may be important, there is very little that can be done to achieve this.

     Another important consideration is how much each worker contributes to the product he is making. In

most factories the worker sees only one small part of the product. Some car factories are said to be

experimenting with having many small production lines rather than a large one, so that each worker

contributes more to the production of the cars on his line. It would seem then that the degree of workers'

contribution is important.

     To what extent does more money lead to greater productivity? The workers themselves cartainly think

this is important, but perhaps they want more money only because the work they do is so boring. Money

just lets them enjoy their spare time more. A similar argument may explain demands for shorter working

hours. Perhaps if companies succeed in making workers' jobs more interesting, they will neither want

more money, nor will shorter working hours be so important to them.
