Overachieving subordinates?

If you have a subordinate who is very potential, would you promote him/her to a higher position? Promoting the person would make the person your 'rival'

Well, this is why it sucks to be an Asian (unless that Asian is a Japanese). The 'kiasu' mentality. Superior tends to be reluctant to promote their subordinates, fearing that by doing so would jeopardize their position.

They would counteract these by being nitpicking. Commenting on every little thing you do.

So, if you are climbing the career ladder, what would you do?

I'm crossing fingers that I won't get a boss like that.
