Final answer:
Peter Drucker coined the term "knowledge worker" to identify professionals who work primarily with information and knowledge, which is increasingly valuable in modern information societies.
Step-by-step explanation:
The term "knowledge worker" was coined by Peter Drucker. This terminology refers to individuals who work primarily with information or who develop and use knowledge in the workplace. Unlike manual workers of the past, whose jobs relied on physical capabilities or operating machinery, knowledge workers are professionals who are employed because of their ability to work with and apply knowledge and information.
Examples of knowledge workers include software engineers, doctors, accountants, engineers, and educators. The rise of the information society has made knowledge workers increasingly important, as their roles are critical in managing the flow of information and creating new knowledge within organizations.
