Suppose you are the absolute expert in your job. You are the person people come to ask directions, policy, etc. You are comfortable and seldom does someone ask you something you have not experienced or do not know the answer to. Someone has to bring an end to this!
While there is something to be said for having people in the organization that truly understand the inner workings and have the ability to work the system, there is also something to be said for people being challenged and growing. This is an extremely delicate balance new leaders must learn through trial and error.
I remember working with a 35-year expert that was completing his last couple of years before retirement. He appeared as someone not interested in a challenge or learning something new. We talked honestly a few times and I learned he was passionate about people learning from his experiences before he left. Long story short, he ultimately took over the new college hire orientation process giving his knowledge away.
Have you been in too comfortable situation where it had to end? Have you helped others see this dilemma without them realizing they were in it? How did it turn out?
