23.Sports have unwritten rules, so does the business—and violators are often punished just as swiftly. Here are some of them. First of all, never dress above your position. Everybody knows that dressing for success is important in the job. It’s also the surest way to draw the not-so-friendly fire of colleagues. Dress slightly “better” if you want—but just slightly. Otherwise you’ll be perceived as a shameless climber. The only time this doesn’t apply is if you run your own business, but even then you should dress in a way that enhances your image while ensuring customers feel comfortable. Besides, never embarrass a peer in a meeting. A colleague proposes an idea. It stinks. Not your job to say so, though. If you’re a supervisor and another supervisor makes a terrible suggestion that doesn’t affect your area or your employees, sit tight. Let someone else, preferably someone above you, shoot it down. Then jump in if you can to modify the idea so it is more workable, giving credit to the other supervisor for raising an important issue, of course. Bad ideas come and go, but professional relationships should be forever. Furthermore, never “borrow” someone’s idea. Business owner, CEO, supervisor, entry-level employee … doesn’t matter. Always give credit where credit is due. Steal an idea and the victim never forgets. And don’t fall back on the old, “Well, they work for me, and we’re a team … so I was just raising the idea on behalf of the team.” No one goes for that excuse but you.(10分)
