This is a true story. Yesterday I was speaking to a manager who ran a team of 65 people. He was depressed because he had been looking to extend some social media tools to help communication across his team. The trouble was that budget was tight, and IT had different priorities. Then a junior member of his team came in and resigned. He said he was leaving to use more of his IT skills, he had a passion for social media and wanted a role that used his skills that he had developed in his spare time.
The manager was depressed, he had never asked the question to his team, he had never thought that the talent might be in his team. People are paid to excel in their role but never forget that might NOT be the extent of their talent. Get close, be curious, look for that hidden talent....before that talent looks for another manager.
