Practical communication in the workplace starts with active listening. Give your full attention to the speaker, maintain eye contact, and avoid interrupting. Ask clarifying questions to ensure understanding. Use 'I' statements when expressing concerns to avoid sounding accusatory. Be concise and specific in your written communications—emails and messages should have clear subject lines and a single purpose. Practice professional body language: sit up straight, make appropriate eye contact, and avoid crossing your arms. Adapt your communication style to your audience, using simpler language when explaining complex concepts to non-experts.
