A large retail organization previously divided work among its four employee-benefitsstaff into distinct specializations. One person answered all questions about superannuation (pension plans), another answered all questions about various forms of paid time off (e. g. vacations), and so on. These jobs were recently restructured so that each person answers all questions for people in a particular geographic area. For example, one staff member is responsible for all employee-benefits inquiries from anyone in a particular geographic region. This job restructuring is an example of: A. self-leadershipB. job enrichmentC. job rotationD. scientific managementE. job specialization
