Working for a healthy, empowering leader is not something we should take for granted. Leadership is like health: You don't realize how important it is until you don't have it! Never take good leadership for granted because it is not as common as we might wish.
If you work for a healthy and empowering leader, consider telling them what it is about their leadership style that you appreciate. Be specific and genuine. Not only will you encourage them but you will reinforce in their thinking those characteristics that are important to their leadership. What we take for granted in a healthy leader may not be the case with a future leader.
If your organization has an ethos of healthy leaders down through the ranks it is because a senior leader and his/her team has created a culture of health and empowerment. This never happens accidentally but is created intentionally, often at significant cost to senior leadership whose commitments are often a threat to the status quo.
When I am with an organization to speak or consult and I find a staff that is happy, empowered and treated well I will specifically mention this to the senior leader. I know they paid a price and worked hard to create a healthy culture. I want to encourage them in that journey. If you work for one of those, thank them, encourage them and pray for them.
