Final answer:
Non-managerial employees are individuals who do not have managerial responsibilities and are found in a variety of roles across many industries, not just in specific ones or in managerial positions.
Step-by-step explanation:
The question asks whether non-managerial employees are only found in specific industries, are always managerial, are found in various roles, or if all customer service employees are managers. To clarify, non-managerial employees are individuals within an organization who do not have managerial or supervisory responsibilities. They are found working in a myriad of roles across different sectors, such as ringing up sales at Home Depot, taking orders at a drive-through, or processing course registrations at a college's registrar's office. Contrary to some of the statements, non-managerial employees are not limited to a particular industry and not all customer service employees are managers. For instance, in a restaurant setting, there are top chefs, sous chefs, kitchen help, servers, greeters, janitors, and business managers all with varied responsibilities ranging from non-managerial to managerial.
Thus, the correct answer to the student's question is that non-managerial employees are found in various roles (c) within different businesses and industries, not confined to specific areas or always holding managerial positions.
