That's because there are no laws anywhere in the US that address hourly-paid workers and salaried workers. And because there are no laws on this, there is nothing to write about on the labour law website.
All the law is concerned about is whether workers are exempt or non-exempt. If you are non-exempt, then you must be paid for all the hours you work, and at time-and-a-half overtime rates for any hours you work in excess of 40 in a seven-day period.
That said, I have noted that you are paid 24 times per year. This means that your paycheques cover more than two seven-day periods. Using the example you provided, it appears that you worked 40 hours in the first seven-day period, 40 hours in the second seven-day period, and eight hours at the beginning of the third seven-day period. Because you are non-exempt, your employer is required to pay you for all of these hours. But because you didn't work in excess of 40 hours in any of the seven-day periods, your employer is not required to pay you any of the hours at overtime rates.
This explanation has nothing whatsoever to do with you being salaried. The exact same explanation would apply if you were hourly. However, things are slightly different in California, where employers are required to pay overtime rates for any hours worked in excess of eight in a single day. In the example you provided, did you work any hours in excess of eight in a single day?
