Final answer:
A knowledge worker applies ideas, information, and knowledge to their work, often requiring advanced education and skills in areas such as math, science, and technology. They are crucial in the information-driven economy and differ from traditional blue-collar jobs, which are less focused on decision-making and specialized knowledge.
Step-by-step explanation:
A knowledge worker is someone who applies ideas, information, and knowledge to their work. This includes professions such as engineers, scientists, doctors, teachers, financial analysts, and computer programmers. Knowledge workers play a vital role in the economy of information societies as they handle the processing and distribution of information rather than tangible goods.
In contrast to traditional blue-collar jobs, which might not require much decision-making or specialized knowledge, knowledge workers demand advanced skills and often higher education. They are also likely participants in the rise of the service sector, such as software programmers or business consultants.
Furthermore, technical writers, for example, require excellent writing skills, including the capacity to convey complex information in a clear and concise manner. As the work environment evolves, employers are particularly interested in individuals with 'transferable skills' who possess specialized knowledge in areas like math, science, and technology, alongside creativity and decision-making abilities.
