Q. I can't work out if a member of my team is an asset or a liability. On the upside, he's a star salesman and consistently outperforms the others. On the downside, he's arrogant, tactless and rubs everyone up the wrong way.
We've had disciplinary problems with him in the past. How do I deal with him?
