Final answer:
The Fair Labor Standards Act (FLSA) does not mandate an 8-hour work day; therefore, options A, B, and C (child labor, overtime pay, minimum wage rates) are regulated by the FLSA, while option D (8-hour work day) is not.
Step-by-step explanation:
The Fair Labor Standards Act (FLSA) is a landmark piece of legislation in the United States that regulates various aspects of employment, including minimum wage, overtime pay, and child labor. However, notably absent from its specific provisions is a mandate for an 8-hour workday. Therefore, among the options provided, the correct answer is D. 8-hour work day.
The FLSA focuses on ensuring fair labor practices, and while it establishes a standard workweek of 40 hours for the purpose of determining eligibility for overtime pay, it does not stipulate a set daily work duration. The Act recognizes variations in work schedules and arrangements, allowing employers to determine the length of the workday as long as the total hours worked in a week by non-exempt employees do not exceed 40, triggering the requirement for overtime pay.
This flexibility acknowledges the diversity of work arrangements in different industries and job sectors. It emphasizes the importance of weekly rather than daily limits, giving employers and employees the latitude to structure workdays based on operational needs and mutual agreements.
In summary, the Fair Labor Standards Act, while instrumental in establishing key labor standards, does not prescribe an 8-hour workday, making it the correct answer among the options presented.
