Introduction: The Fair Labor Standards Act and Its Role in Overtime Law

The Fair Labor Standards Act (FLSA) of 1938 remains the cornerstone of federal wage and hour law in the United States. Enacted during the Great Depression to combat unfair labor practices, the FLSA established a federal minimum wage, set rules for child labor, and codified overtime pay protections. For over 80 years, the FLSA has evolved through amendments, regulations, and court rulings, but its core mission endures: to ensure that workers receive fair compensation for the hours they dedicate to their jobs. Understanding overtime law under the FLSA is essential for employers seeking compliance and for workers wanting to protect their paychecks.

This comprehensive overview breaks down the key provisions of overtime law, explains who is covered and who is exempt, details how overtime pay is calculated, and covers recent regulatory changes. Whether you are an HR professional, a small business owner, or an employee trying to understand your rights, this guide provides clear, actionable information. For the full text of the law, consult the U.S. Department of Labor (DOL) FLSA page.

How Overtime Works Under the FLSA

The FLSA’s overtime provision is straightforward on paper: covered, non-exempt employees must receive overtime pay at a rate of at least one and one-half times their regular rate of pay for all hours worked beyond 40 in a single workweek. This 40-hour threshold has remained unchanged since the law’s inception, though the definition of “regular rate” has been refined over time. Employers cannot average hours across multiple weeks or use a two-week pay period to avoid paying overtime; the calculation is always per workweek.

Overtime applies to each workweek independently. If an employee works 50 hours one week and 30 the next, the employer must pay overtime for the 10 extra hours in the first week, regardless of the shorter second week. This per-workweek rule is one of the most common areas of employer confusion and a frequent target of DOL enforcement actions.

What Counts as “Hours Worked”?

Not all time spent on work activities is always counted toward overtime, but the FLSA takes a broad view. “Hours worked” includes time during which an employee is required to be on duty or on the employer’s premises, or is “suffered or permitted to work.” This can include:

  • On-call time when restrictions on the employee’s freedom are significant
  • Waiting time during a shift (e.g., waiting for assignments)
  • Training time that is required and job-related
  • Travel time during the workday (excluding ordinary commute)
  • Short rest breaks (usually under 20 minutes) as they benefit the employer

By contrast, bona fide meal breaks of 30 minutes or more are generally not considered hours worked if the employee is completely relieved of duty. The DOL’s Fact Sheet #22 on hours worked provides detailed guidance on these distinctions.

Who Is Covered by Overtime Laws? Exempt vs. Non-Exempt Employees

The FLSA divides employees into two broad categories: non-exempt (entitled to overtime and minimum wage) and exempt (not entitled to overtime). The classification depends primarily on job duties, salary basis, and salary level. Employers often misclassify workers as exempt to avoid paying overtime, which can lead to costly lawsuits and DOL penalties.

Non-Exempt Employees

Non-exempt employees are entitled to the federal minimum wage ($7.25 per hour as of 2025) and overtime premium for hours over 40 per week. Most hourly workers fall into this category, but some salaried employees may also be non-exempt if their duties or salary level do not meet exemption criteria. There is no cap on overtime pay; employees must be paid for every overtime hour worked.

Exempt Employees

Exempt employees are not eligible for overtime pay. To be considered exempt, an employee must generally meet three tests:

  1. Salary basis test: The employee must be paid a predetermined and fixed salary that is not subject to reduction based on quantity or quality of work. Most exempt employees must receive their full salary in any week they perform work, regardless of hours.
  2. Salary level test: The employee must earn at least the minimum salary threshold set by the DOL. As of July 1, 2024, the standard salary level for the executive, administrative, and professional exemptions is $844 per week ($43,888 annually). This threshold is scheduled to increase to $1,128 per week ($58,656 annually) by January 1, 2025.
  3. Duties test: The employee’s primary job duties must fall into one of the recognized exemption categories: executive, administrative, professional (including learned professionals like doctors and lawyers and creative professionals), computer employee, or outside sales.

Other exemptions exist for certain industries and roles, such as agricultural workers, certain retail commission employees, and highly compensated employees (HCEs). HCEs earning $132,964 or more annually (as of July 1, 2024) may be exempt if they perform at least one of the exempt duties on a regular basis.

Common Misclassifications

Many employers misclassify employees as “independent contractors” or place them under an incorrect exemption category. For example, a salaried employee who earns $45,000 per year but spends most of their time performing routine manual tasks or clerical work is likely non-exempt. The duties test is the most important factor; job titles alone do not determine exemption. The DOL provides detailed fact sheets for each exemption type, such as Fact Sheet #17A on executive, administrative, and professional exemptions.

Calculating Overtime Pay: Regular Rate and Special Situations

Overtime is calculated as 1.5 times the employee’s “regular rate of pay.” The regular rate is not simply the hourly wage; it includes most forms of compensation, such as nondiscretionary bonuses, commissions, shift differentials, and piece-rate earnings. Even a flat sum for completing a task or a production bonus must be factored into the regular rate for that week.

Simple Hourly Employee Example

An employee earns $20 per hour for a 40-hour week and works 45 hours. Total straight-time pay is 40 × $20 = $800 + 5 hours at $20 = $100 (for the first five overtime hours, the regular rate covers the base). Overtime premium = 5 hours × $10 (half of $20) = $50. Total pay = $800 + $100 + $50 = $950. Alternatively, many employers simply pay 1.5× for every overtime hour: 45 hours × $20 = $900, but that only gives $900, missing the premium. The correct method: 45 hours × $20 = $900 plus an extra $10 per overtime hour (the “half-time” premium) = $900 + $50 = $950.

Salaried Non-Exempt Employees

A salaried non-exempt employee has a fixed salary that covers a certain number of hours (often 40). If the salary is intended for a 40-hour week, the regular rate is the weekly salary divided by 40. For example, a $800 weekly salary yields a $20 regular rate. For any overtime hours, the employee receives half-time ($10) on top of the salary (which already covers straight-time) for each overtime hour, plus the salary itself.

Tipped Employees and Overtime

Tipped employees (e.g., servers, bartenders) under the FLSA may be paid a direct cash wage as low as $2.13 per hour if they receive enough tips to reach the $7.25 minimum wage. For overtime, employers must calculate overtime pay based on the full minimum wage ($7.25), not the reduced cash wage. The DOL’s Fact Sheet #15 on tipped employees explains that the overtime rate for tipped workers is (full minimum wage) × 1.5, and the employer can take a tip credit for up to 50% of that rate.

Fluctuating Workweek Method

In some cases, employers may use the “fluctuating workweek” (FWW) method for employees whose hours vary week to week but who are paid a fixed salary regardless of hours. Under FWW, the regular rate changes each week: divide the fixed salary by the total hours worked. Overtime premium is then 0.5× that regular rate per overtime hour. This method requires that both employer and employee understand and agree to the arrangement, and that the salary is high enough to never drop below minimum wage per hour. The DOL has provided updated guidance on the legality of FWW in recent years.

Recordkeeping Requirements Under the FLSA

Employers must maintain accurate records of hours worked and wages paid for at least three years. For non-exempt employees, records must include time of day and day of week when the workweek begins, total hours worked each workday and each workweek, regular hourly rate, overtime pay calculations, additions to or deductions from wages, and total wages paid each pay period. The DOL can request these records during an investigation, and failure to keep them can lead to adverse inferences in a wage claim. Employers should use time clocks, digital time tracking, or signed timesheets to ensure accuracy.

Recent Changes and Enforcement: The 2024 Salary Threshold Update

The most significant recent change to overtime law is the DOL’s final rule issued in April 2024, which raised the salary threshold for the executive, administrative, and professional exemptions. Effective July 1, 2024, the minimum salary for the standard exemption increased from $684 per week ($35,568 annually) to $844 per week ($43,888 annually). A further increase to $1,128 per week ($58,656 annually) is scheduled for January 1, 2025. The highly compensated employee threshold rose from $107,432 to $132,964 per year on July 1, 2024, with a second increase to $151,164 set for January 1, 2025. These changes will automatically update every three years based on wage data.

Employers must evaluate their workforce to ensure that salaried exempt employees meet the new salary levels. If an employee’s salary falls below the new threshold, the employer must either raise their salary to the minimum, reclassify them as non-exempt and begin paying overtime, or adjust duties to meet a different exemption (like outside sales, which has no salary test). Failure to comply can result in back wages, liquidated damages, and penalties. The DOL has increased its enforcement efforts under the current administration, with overtime violations being a top priority.

Implications for Employers and Employees

For employers, the consequences of FLSA overtime violations are significant. The DOL may investigate after an employee complaint or as part of a targeted industry sweep. Civil penalties for willful or repeated violations can reach $2,104 per violation (adjusted annually for inflation). Employees can also file private lawsuits under the FLSA to recover unpaid overtime, plus an equal amount in liquidated damages (effectively double damages), and attorney’s fees. Class action overtime lawsuits are common in retail, hospitality, healthcare, and the gig economy.

For employees, understanding overtime rights is essential to recovering fair pay. Many workers are unaware that their employer’s classification of them as exempt may be incorrect, or that performing off-the-clock work (e.g., checking emails after hours) counts toward hours worked. The DOL’s Wage and Hour Division provides a confidential complaint process, and employees cannot be retaliated against for asserting their FLSA rights.

Best Practices for Compliance

To minimize the risk of overtime violations, employers should implement the following practices:

  • Conduct an audit of all employee classifications, using the duties test and current salary thresholds. Reclassify any misclassified workers before a complaint arises.
  • Update pay policies to reflect the new salary levels. Communicate changes to affected employees and adjust budgets accordingly.
  • Implement reliable time tracking. Use digital systems that prevent employees from clocking in early or working off the clock. Prohibit unauthorized overtime, but pay all overtime that occurs.
  • Train managers on FLSA rules, especially regarding what constitutes compensable time (off-the-clock work, remote work, meeting attendance, etc.).
  • Document pay practices. Maintain clear written policies for overtime authorization, break periods, and recordkeeping.
  • Consider state law differences. Many states have their own overtime laws with lower thresholds or stricter definitions (e.g., California requires daily overtime after 8 hours). Ensure compliance with both federal and state laws where applicable.

Conclusion

The Fair Labor Standards Act’s overtime provisions serve as a fundamental protection for American workers, ensuring that extra hours of labor are compensated at a premium rate. While the basics of the 40-hour workweek and 1.5× pay have remained constant, the regulatory landscape around exemptions and salary thresholds continues to evolve. The 2024 salary updates represent the most ambitious expansion of overtime eligibility in decades, potentially bringing millions of workers into non-exempt status. Employers must stay vigilant and proactive in classifying employees correctly and tracking hours accurately. Employees should educate themselves about their rights under the FLSA and seek recourse if they suspect violations. By understanding the interplay of duties, salary, and hours worked, both parties can foster a fair and compliant workplace.
