Business and professional communication, one aspect of organizational communication, involves intentional messages voluntarily exchanged between two or more people in for‐profit companies. Business and professional communication instruction addresses written communication (résumés, cover letters, proposals, reports, formal performance feedback, and electronic messages such as email and material posted online), oral communication (interpersonal, small group or team, and public speaking), and listening. In practice, business and professional communication includes leadership and followership, group decision making processes, and feedback. Constructivism, expectancy violation theory, and social presence theory represent three ways to explain and predict business and professional communication. The multigenerational, co‐cultural workplace with its increasingly diverse options for creating and delivering messages requires lifelong learning for all employees.
