I agree with this blog.
more than true, it is very true.
'a study' - what study? If people are genuinely 'good' they'll bypass the manager issue.
Sorry Anonymous, but that is just not real at all. A manager is above you on the chain of command, one's freedom to produce is therefore limited to what is allowed from above. And than there's the atmosphere at work, motivation, etc et etc. Your comment is welcome but lacks on interpretation.
