Running a business would be easy if only you didn't have to manage people. The bigger your company grows, the smaller the likelihood that everyone in it will be easy to supervise. As the boss you always (or almost always) have the option to terminate anyone who is truly a drag on your company. But good talent is hard to find, so before you go down that road, it's worth the effort to try and make a difficult person work more effectively within your company.
When faced with a problem personality, most of us do one of two things: We either confront the person head-on, leading to escalating hostility, or else avoid dealing with him or her and leave the problem to worsen. Neither is an effective solution, and as your company's leader, neither is an option.
