Q#2)Ethical decision: Is Goal-Setting manipulation

Managers are interested in the subject of motivation because they are concerned with learning how to get the most effort from their employees. Is this ethical? For example, when managers set hard, specific goals for employees. , aren't they manipulating them.

Manipulation is defined as:

i."To handle, manage, or use, especially with skill, in some process of treatment or performance;

ii.To manage or influence by artful skill;

iii.To adapt or change to suit one's purpose or advantage"

Aren't these definitions compatible with the notion of managers skillfully seeking to influence employee productivity for the benefit of the manager and the organization?

Do managers have the right to seek control over their employees?
