What are the differences among the four levels of managers in the organizational pyramid?

The four levels of managers are:

The higher the position on the organizational pyramid, the tasks and responsibilities also differ. Entry level managers generally supervise the tasks of entry level workers, e.g. sales clerks.

Low level managers generally have both supervisory and general management functions, e.g. a store manager must make sure that everyone does their job properly, but also must make administrative decisions like hiring, overseeing inventory, etc.

Middle level managers are generally functional managers, meaning that they are in charge of a certain area within the organization, e.g. human resources, finances, marketing, etc.

Upper level managers are responsible for developing the organization's strategies and long term goals, their focus should always be on the big picture and the future of the organization,  not just one part of it.
