 Employees who might have been able to serve multiple roles and make their own decisions in a flat organization are constricted to a single role and must make company changes through the management structure.

Politics

Many levels of management mean a great amount of bureaucracy for the organization, and this can lead to problems.

When a company has many levels of management, it tends to produce ideas only at the top, with a few executives creating most of the company's strategy.
