Nanomanagement is an extremely poor type of management where the manger not only overmanages their employees' work, but all of the employees' other tasks on a daily basis. This includes but is not limited to delegaing meaningless tasks like copy and pasting information, asking employees to send an email for them, etc.
Instead of giving employees general instructions, room to use their imagination and empowering them, a nanomanager not only assesses every step, but also assigns and manages each little task for each step.
This type of management may be motivated by but not limited to the manager's concern for details, the manager not having any work of their own to do, feeling insecure about their position as manager and having the need to demonstrate their power to their employees.
The effect of nanomanagement will be de-motivated employees, lowered morale, increased resentment and low retention
This nanomanagement is out of control I need to create a project plan just to wipe my ass and make sure my manager is there while I do it!
