Here’s a tale of two bosses I had when I worked at Yahoo!
The first boss (call him Andy) was a good guy. He was likeable, funny and very smart and fiercely ambitious. However, over time it became clear to the eight or so of us on his team that Andy was more interested in how we could help him climb higher in his career than how he could help us in our careers. He was pleasant and friendly, but showed little interest in our career goals. He helped us with our jobs, but “benign neglect” seemed to be his guiding principle regarding our careers. He was all about driving results for his boss. Fair enough.
My second boss (call him Bill) was different.
