Which of the following is NOT a form of workplace communication?

Personal opinion letters are not considered a formal form of workplace communication as they typically reflect individual thoughts or viewpoints that are not part of official communication channels within a workplace. Workplace communication generally aims to convey information relevant to operations, procedures, or directives that impact the work environment and team collaboration.

In contrast, verbal communication encompasses face-to-face discussions, meetings, and telephone conversations that contribute to day-to-day interactions among team members. Written instructions are essential for providing clear guidelines and procedures that employees need to follow, ensuring everyone understands their tasks and responsibilities. Signage serves as visual communication intended to convey important messages or safety information in shared workspaces, reinforcing protocols and enhancing safety measures. All these forms are integral to maintaining structured and effective communication within an organization.
