Answer: Boris has achieved the level of middle manager.
There are three levels of management in an organization - the top level management, middle management and low level management.
The top level of management consists of executives who are responsible for taking strategic decisions and formulating plans.
The middle level of management consists of executives who are responsible for communicating these objectives to the workers and actually implement the plans.
The low level of management consists of workers who actually perform the tasks given to them by the middle management.
Middle managers act as a link between the top and low levels of management. They are responsible for implementing the strategies finalized by the firm and for their subordinates.
