Briefly explain the difference between the three managerial strategies described in the textbook.

Although the six structural variables can be designed and combined in a number of ways,the following three main patterns of structural variables,known as "managerial strategies," have formed.The classical approach to management assumes that people are lazy,dislike work,and need to be motivated to work by financial rewards or the threat of removal of these rewards.Jobs are narrowly designed and employees closely supervised.The human relations approach assumes most employees dislike work but can be induced to work in order to satisfy their social needs,which results in a different approach to leadership,communication,control,and rewards from the classical approach.Supervisors are controlling but employee-oriented,using a paternalistic style.High-involvement management assumes that people are motivated by the intrinsic rewards flowing from interesting and challenging work,and it differs from the other two managerial strategies in all six structural variables.
