Effective leadership means that the words and actions of the manager encourage the respective employees to participate in achieving the goals. These can also be goals of organizational or personal development. Leadership means taking or retaining the initiative.
The multitude of leadership styles does not allow a preference for a certain uniform style across all leadership situations. Managers naturally want to find and maintain their own personal style. They should decide for themselves what they are responsible for and what the employee is responsible for.
Learn (as a manager) to understand how your actions and words actually influence your employees. To do this, you should first optimize your personal self-perception to such an extent that will and leadership harmonize with each other. The recommended way to do this is to take advantage of special management coaching.
This will help you to recognize how your employees perceive you. This is not only important for new managers, but also makes sense for veteran managers, because not only do employees change over time, but their perceptions are also subject to change.
