Yet, despite the ovious rewards Of engaging in office politics - a better job, a raise, praise- many people are still unable or unwilling - to "play the game."

　　"People assume that office politics involves some manipulative (工于心計(jì)的) behavior," says Deborah Comer, an assistant professor of management at Hofstra University. "But politics derives from the word polite. It can mean lobbying and forming associations. It can mean being kind and helpful, or even trying, to please your superior, and thenexpecting something in return."

　　In fact, today, experts define office politics as proper behavior used to pursue ones own self-interest in the workplace. In many cases, this involves some form of socializing within the office environment - not just in large companies, but in small workplaces as well.

　　"The first thing people are usually judged on is their ability to perform well on a consistent basis," says Neil P. Lewis, a management psychologist. "But if two or three candidates are up for a promotion, each of whom has reasonably similar ability, a manager is going to promote the person he or shelikes best. Its simple human nature."

　　Yet, psychologists say, many employees and employers have trouble with the concept of politics in the office. Some people, they say, have an idealistic vision of work and what it takes to succeed.
