Some managers act like employees
Not all managers behave like managers. How can you identify them, and thus also know who your good managers are?
If a subordinate frequently comes to you with a problem, expecting you to give him the solution, this subordinate is acting like an employee, even though his title and pay level might indicate that s/he is a manager.
Employees present problems. Managers should present solutions.
Many managers find it flattering when their subordinates bring them problems to solve. But if they encourage such behavior, they are paying managerial salaries to people who do not behave like managers.
Sometimes subordinates like to bring problems rather than solutions to their managers because by doing so they don’t have to take responsibility for the decision.
Even when both the subordinate and his/her manager prefer this process of problem-solving, it is undesirable, because it does not develop management skills. On the contrary, it keeps these managers disempowered, dependent, and subordinary.
