This document outlines four basic styles of communication: passive, aggressive, passive-aggressive, and assertive. Passive communication is avoiding expressing opinions and needs, leading to feelings of anxiety and resentment. Aggressive communication violates others' rights through domination and criticism. Passive-aggressive communication involves indirect anger through sabotage while appearing cooperative. Assertive communication clearly states opinions and needs without violating others' rights, allowing individuals to feel in control and connected to others.
