Effective communication involves both verbal and nonverbal skills. Verbal communication can be oral like conversations or written like emails and reports. Nonverbal communication includes body language through facial expressions, posture, gestures, and how people use personal space. Good communication is important for situations like teaching a class, job interviews, group discussions, presenting ideas, appraisals, instructing staff, asking for raises, client interactions, speeches, team meetings, and brainstorming sessions. Body language skills such as making eye contact and having aware facial expressions are also crucial parts of communicating successfully.
