Final answer:
Knowledge workers are responsible for designing products or services and creating new knowledge for the firm.
Step-by-step explanation:
Knowledge workers are responsible for designing products or services and creating new knowledge for the firm. Unlike service workers who focus on providing services, knowledge workers use their expertise and specialized skills to develop innovative solutions. They often have higher levels of education and possess critical thinking and decision-making abilities.
For example, a software engineer would be considered a knowledge worker because they design and create software products and constantly update their knowledge in this field. On the other hand, a coal miner is not typically responsible for designing products or creating new knowledge for the firm.
