When you were in school, you probably learned about the appropriate ways to behave in the classroom and on the playground. You knew that it was polite to raise your hand when you wanted to add something to a classroom discussion, that you needed to wait your turn for the water fountain or in line at the cafeteria, and if you wanted to make and keep friends, you needed to be a kind person to others.

Unfortunately, too many people forget these simple rules for succeeding in school once they enter the real world—and they get a job. But there is still a need for certain manners in the office, the conference room or at a business lunch or dinner. Why else would manners classes for employees be such hot commodities these days? Ask any etiquette instructor about good behavior, and she'll tell you that it's the key to succeeding in business, which is why professionals often need a brush-up lesson on how to behave while doing business.
