Chapter 4 deals with job design and work flow. What I have always thought interesting is job description. Many times employers ask their employees to do things that are not included in their job descriptions. As a result, most employers write something like "other tasks as assigned" into their job descriptions. Is there a limit to what an employer can say is under the "other tasks" category? Should an employee always do what is asked, even when it may be a very extreme interpretation of "other tasks"?
