Managing Employees: Getting Your Priorities Straight
I would suggest that "management by hope" or even any single style of management
is not a successful way to manage and motivate employeesthe key is to learn about each style and then combine the best of each to develop your own philosophy. Moreover, don't expect that you can use the same management style for all of your employees, but rather customize it to each individual.
