Final answer:
The HR manager's strategy to adjust the workweek based on customer project start dates utilizes the flexible provisions of the FLSA, and while it is not restricted to any specific day federally, state laws might impose additional requirements.
Step-by-step explanation:
The strategy presented by the HR manager of the Tractor and Belt Company (TBC) suggests flexibility in determining the starting day of the workweek based on client project commencement. This approach is addressed by option A, which emphasizes the Fair Labor Standards Act (FLSA)'s provisions for flexible workweeks that may benefit small businesses.
Option B cautions against changing the designated start day, but it's essential to note that the FLSA does not require the workweek to begin on any specific day, thus making option B generally inaccurate. As for option D, the FLSA does not mandate that workweeks begin on Sunday; hence, this option is incorrect.
Finally, option C correctly suggests that while the FLSA provides flexibility at the federal level, one must consider that state laws and regulations might have additional requirements regarding workweeks. Therefore, it is crucial for TBC to be aware of both federal and state regulations when implementing such a strategy.
