Which of the following types of businesses is covered by the FLSA regardless of annual sales?

The Fair Labor Standards Act (FLSA) includes specific provisions and coverage for various types of businesses. Construction companies are generally covered by the FLSA regardless of their annual sales figures. This is primarily due to the nature of construction work, which often involves interstate commerce, such as using materials or equipment that have moved across state lines.

In contrast, the other business types listed have certain thresholds based on annual sales. For instance, retail stores and restaurants have to meet specific sales limits to be covered under the FLSA provisions. Legal firms, although they might engage in interstate commerce, have a different context regarding their business operations and are not automatically covered under the same criteria.

Therefore, construction companies are uniquely positioned under the FLSA as being covered regardless of their annual sales, focusing on the interstate nature of their work. This distinction emphasizes the special status of certain industries like construction within labor law, providing protections for workers in those fields.
