Glasser's comparison between an internal control psychology and an external control psychology lends itself very well to the idea of management. 

Employers cannot "make" their employees work! Only in the context of caring leadership will an employer be able to influence the workers in a positive way.

Glasser contrasts the approach of a "Boss Manager" who relies on external control psychology with that of a "Lead Manager" who operates from a Choice Theory perspective:

BOSS MANAGEMENT  v LEAD MANAGEMENT 
sets the task and standards v engages in discussion of quality of the work 
tells rather than shows v shows or models the job 
inspects or grades the work v asks workers to evaluate their own work 
uses coercion v non-coercive and non-adversarial
