Which of the following is an example of a non-exempt worker?

A non-exempt worker is typically entitled to overtime pay under the Fair Labor Standards Act (FLSA). This designation usually applies to workers who are paid hourly and engage in job functions that do not involve a high level of decision-making or managerial duties.

In this context, a plumber fits the definition of a non-exempt worker. Plumbers are often hourly workers who are not engaged in administrative or professional tasks that would qualify them for the exempt status. Their roles usually involve technical skills related to plumbing systems, which do not generally place them in a managerial category with regard to employee supervision or policy-making.

The other roles mentioned, such as facility manager, stadium director, and graphic designer, typically require a higher level of responsibility, discretion, and decision-making. These positions often have a salary structure that may include conditions that exempt them from overtime based on their managerial or professional duties. Hence, they would not typically fall under the non-exempt category like the plumber does.
