Lions are respected for their courage and skill. Likewise, leaders are known for similar attributes. But can you have too many lions in one jungle?
HR professionals often hire with an eye towards those candidates who have potential to move into management. And, although “future management” is an important consideration, I don’t think the goal aims high enough. I strongly recommend you hire individuals who are “future leaders.” Not everyone who can and will someday lead necessarily wants to be a manager.
