When it comes to managers, it's hard not to say their role is BS for many of us. I've never had a truly good manager (19 in 10 years). Many of their perceptions don't match with mine or the other team members.
A good manager is often invisible. If you forgot they were there, you were either lucky that everything in the org was going right (or was so far away it didn't matter), or they were really good at shielding you from the fact that everything was not going right (and making it seem like that didn't matter). :)
