Unfortunately, "leader" has become a workplace buzzword.
We have all seen the infographics comparing the characteristics of a boss to a leader, or management to leadership. They are meant to show there is a distinct difference between someone in a managerial role that has true leadership traits, and some who is simply in a position of power based solely on education, experience, and/or seniority.
However instead of inspiring people in positions of authority with marginal leadership capabilities to strive for self improvement. This trend of rebranding managers as leaders is simply that too often. Just rebranding. The same poor management, just call leadership by the poor managers.
Seems many think if they simply call themselves leaders enough it will be true. It won't. Bad bosses will remain bad bosses, regardless to what they decide to call themselves.
Be cautious of the self-described leader. Too often they are a mediocre manager at best that has a shelve full of business books they've only skimmed through enough to pick up that "leader" is what the successful people call themselves. Only they are not actually doing what makes a true leader a leader. Once again there are no shortcuts on the path.
