The Department of Labor set the rules.

OVERTIME RULES

OVERTIME RULES

On September 24, 2019, the Department of Labor issued its final overtime rule to increase the minimum salary threshold for executive, administrative, and professional exemptions from $455 per week ($23,660 annually) to $684 per week ($35,568 annually). The new rule went into effect on January 1, 2020.

Who’s Impacted?

It’s estimated that nearly 1.3 million United States workers will be
eligible to receive time-and-a-half pay for hours worked more than
40 hours per week. Employees who make less than $35,568 annually
must either obtain a raise to meet the new threshold amount or be
paid overtime, even if they’re classified as a manager or a professional

IS OVERTIME AFTER 8 HOURS OR 40 HOURS IN Florida?

Florida law doesn’t outline overtime pay for the workweek, so the federal standard applies throughout the state. The Fair Labor Standards Act (FLSA) determines jobs’ exempt or nonexempt status and overtime requirements. The Fair Labor Standards Act (FLSA) establishes the 40-hour workweek limit and requires employers to pay non-exempt employees 1.5 times their base pay for any time worked above the 40-hour limit.  These are rules under the Department of Labor.

Federal Labor Laws
Federal labor laws do not have state-specific exemptions in its Florida overtime rules, meaning all non-exempt employees must be paid overtime pay of time and a half for any hours worked over 40 during a workweek.
Generally, workers can legally work as many hours in a day as they choose to or as their employer requires. No federal or state law caps the number of hours in a workday for most workers. However, workers under 16 cannot work longer than 8-hour days. Mar 29, 2022 
A Non-Exempt Worker
A non-exempt worker is entitled to minimum wage and overtime pay. There are only a limited number of exemptions from these legal protections. While many salaried employees fall into one of these exemptions, not all do.

Overtime Pay Is One-and-One-Half (1.5) Times the Worker’s Regular Hourly Rate.

Under the FLSA, however, an employee who works a single 24-hour shift has not necessarily earned any overtime pay. Therefore, in some cases, they would still be below the 40 hours necessary for the week.

However, many state employment laws are more generous as to overtime pay. Check your state laws where you do business.
