Assertive vs. passive-aggressive behavior

Now consider passive-aggressive behavior. If you communicate in a passive-aggressive manner, you may say yes when you want to say no. You may be sarcastic or complain about others behind their backs. Rather than confront an issue directly, you may show your anger and feelings through your actions or negative attitude. You may have developed a passive-aggressive style because you're uncomfortable being direct about your needs and feelings.

What are the drawbacks of a passive-aggressive communication style? Over time, passive-aggressive behavior damages relationships and undercuts mutual respect, which makes it difficult for you to get your goals and needs met.
