The burden of proof in FLSA wage and hour claims does not sit with one side. The worker starts by proving the Act covers them and that they performed work they were not properly paid for. From there, the burden shifts to the employer at several points: to prove any exemption it wants to rely on, to prove good faith if it wants to escape liquidated damages, and even to prove the number of hours worked when it failed to keep the records the law required. The standard throughout is preponderance of the evidence — more likely true than not.
What the Worker Has to Prove First
Before any pay dispute is examined, the employee has to show the FLSA applies. There are two paths. Individual coverage looks at your specific duties: processing credit card transactions routed through out-of-state banks, shipping goods across state lines, or regularly communicating with people in other states will do it. Enterprise coverage looks at the business, which qualifies if it has employees engaged in interstate commerce and generates at least $500,000 in annual gross sales.1Office of the Law Revision Counsel. 29 USC 203 – Definitions Hospitals, schools, and residential care institutions are covered regardless of dollar volume.2eCFR. 29 CFR Part 779 – The Fair Labor Standards Act as Applied to Retailers of Goods or Services
The worker carries the full responsibility of establishing one of these paths, usually with tax records, sales reports, or job descriptions. A claim that never clears this threshold gets dismissed before the wage numbers are ever discussed.
A related threshold question is whether you are an employee at all. The FLSA only protects employees, and many companies label workers as independent contractors to avoid overtime and minimum wage. The Department of Labor applies an economic reality test that asks whether the worker is economically dependent on the employer or truly running an independent business, weighing factors like the employer’s control over the work, the worker’s opportunity for profit or loss, and how permanent the relationship is.3U.S. Department of Labor. Fact Sheet 13 – Employment Relationship Under the Fair Labor Standards Act4eCFR. 29 CFR 795.110 – Economic Reality Test A “1099 contractor” label does not settle the question.
Once coverage is established, the worker must present enough evidence to show they performed work without the required minimum wage or overtime pay. The federal minimum wage is $7.25 per hour, and overtime is one and a half times the regular rate for hours beyond 40 in a workweek.5Office of the Law Revision Counsel. 29 USC 207 – Maximum Hours Minute-by-minute precision is not required. Courts want enough evidence for a reasonable estimate — personal calendars, handwritten logs, text messages referencing work hours, or detailed testimony about the daily routine can be enough.
The employee also has to show the employer knew or should have known about the uncompensated work. The Act reaches work that is “suffered or permitted,” which does not require an express request for overtime.6U.S. Department of Labor. Fact Sheet 22 – Hours Worked Under the Fair Labor Standards Act A supervisor who sees you working through lunch has actual knowledge. A workload that cannot realistically be finished in 40 hours, with no questions asked about how it gets done, supplies constructive knowledge. Hours worked secretly from home, with no signal to the employer, are much harder to recover.
When Missing Employer Records Shift the Burden on Hours
Federal law requires every covered employer to keep records of each employee’s daily and weekly hours, wages paid, and rate of pay.7Office of the Law Revision Counsel. 29 USC 211 – Collection of Data The regulations spell out the details: start and stop times each workday, daily and weekly straight-time earnings, overtime premium pay, deductions, and total wages per pay period.8eCFR. 29 CFR 516.2 – Employees Subject to Minimum Wage or Minimum Wage and Overtime Pay Requirements
When the employer fails at that duty, the proof standard changes. In Anderson v. Mt. Clemens Pottery Co., the Supreme Court held that an employer that violates its recordkeeping obligations does not get to benefit from the resulting evidentiary gap. Letting the employer off because the worker cannot prove exact hours would reward the employer for breaking the law.9Legal Information Institute. Anderson v. Mt. Clemens Pottery Co., 328 U.S. 680
Under Anderson, the employee only has to prove two things: that they performed work without proper compensation, and enough facts to allow a just and reasonable inference about the amount of that work. Once the employee clears that bar, the burden shifts to the employer, who must either produce evidence of the precise hours or undermine the reasonableness of the employee’s estimate. If the employer does neither, the court can award damages based on the worker’s approximation.9Legal Information Institute. Anderson v. Mt. Clemens Pottery Co., 328 U.S. 680
This is where many employers lose. A worker testifies to 15 hours of weekly overtime, the employer has no time cards to contradict it, and the estimate stands.
When the Employer Has to Prove an Exemption
If the employer says the worker is exempt from overtime, the employer carries the burden of proving every element of that exemption. The Supreme Court has long treated FLSA exemptions as affirmative defenses to be narrowly construed.10Library of Congress. Corning Glass Works v. Brennan, 417 U.S. 188 (1974) This is a big deal in practice, because misclassification as an exempt “manager” or “administrator” is one of the most common ways overtime goes unpaid.
For the common white-collar exemptions — executive, administrative, and professional — the employer has to prove both a salary component and a duties component. On salary, the current threshold is $684 per week ($35,568 per year) after a federal court vacated the Department of Labor’s 2024 update; highly compensated employees must reach $107,432 in total annual compensation with at least $684 per week on a salary basis, and computer employees paid hourly must earn at least $27.63 per hour.11U.S. Department of Labor. Earnings Thresholds for the Executive, Administrative, and Professional Exemption On duties, the employer has to show the worker’s primary duty actually matches the exemption category the employer picked.12eCFR. 29 CFR Part 541 – Defining and Delimiting the Exemptions for Executive, Administrative, Professional, Computer and Outside Sales Employees
“Primary” means the principal or most important duty. An employer cannot put a “manager” title on someone who spends most of the day stocking shelves and expect the exemption to hold. Titles do not decide the question; what the worker actually does day to day decides it.
Who Proves Willfulness for the Three-Year Limitations Period
How far back a claim reaches depends on willfulness. The default statute of limitations is two years. If the violation was willful, it extends to three.13Office of the Law Revision Counsel. 29 USC 255 – Statute of Limitations That extra year of back pay is often substantial, so the fight over willfulness is a real one.
The employee bears the burden of proving willfulness. Under McLaughlin v. Richland Shoe Co., the question is whether the employer knew its conduct violated the FLSA or showed reckless disregard for whether it did. Reckless disregard means the employer had reason to investigate its compliance and failed to.14GovInfo. 29 CFR Part 578 – Minimum Wage and Overtime Violations, Civil Money Penalties An employer that receives a complaint about unpaid overtime and ignores it is likely acting willfully. An employer that made a genuine mistake after consulting counsel is probably not.
Who Proves Good Faith to Avoid Liquidated Damages
An FLSA violation of the minimum wage or overtime rules ordinarily costs the employer the unpaid wages plus an equal amount in liquidated damages, doubling the recovery.15Office of the Law Revision Counsel. 29 USC 216 – Penalties Liquidated damages are the default. The burden of getting out of them rests entirely on the employer.
To do that, the employer has to convince the court of two things: that the violation was committed in good faith, and that it had reasonable grounds to believe its conduct was lawful.16Office of the Law Revision Counsel. 29 USC 260 – Liquidated Damages Good faith means an honest intention to understand and comply with the law. Reasonable grounds means that belief was objectively justifiable. Not knowing about the FLSA is not enough.17eCFR. 29 CFR 790.22 – Discretion of Court as to Assessment of Liquidated Damages
Even when both prongs are met, the court has discretion to reduce or eliminate liquidated damages but is not required to. If the employer fails to carry this burden, full liquidated damages are mandatory.17eCFR. 29 CFR 790.22 – Discretion of Court as to Assessment of Liquidated Damages
The Three-Step Burden in Retaliation Claims
The FLSA also forbids firing or punishing a worker for filing a wage complaint, testifying, or otherwise exercising rights under the Act.18Office of the Law Revision Counsel. 29 USC 215 – Prohibited Acts A retaliation claim moves through three stages, with the burden shifting at each step.
First, the worker has to show a protected activity, a materially adverse action, and a causal link between them. A materially adverse action is any employer response that would discourage a reasonable person from exercising their rights: termination, demotion, schedule changes, unwarranted write-ups, or reassignment to undesirable duties.19U.S. Equal Employment Opportunity Commission. Questions and Answers – Enforcement Guidance on Retaliation and Related Issues Timing frequently supplies the causation piece; a firing two weeks after a wage complaint is more compelling than one a year later.
Second, the burden shifts to the employer to articulate a legitimate, non-retaliatory reason for what it did — documented performance issues, attendance problems, a policy violation. Performance reviews and written warnings that predate the protected activity carry weight. Records that appear only after the complaint tend to look manufactured.
Third, the burden returns to the employee to prove pretext: that the stated reason is false, implausible, or inconsistent with how similarly situated workers have been treated. A recent glowing review contradicting a “poor performance” firing is the kind of evidence that gets pretext across. A successful retaliation claim exposes the employer to reinstatement, back pay, and liquidated damages equal to the back pay owed.15Office of the Law Revision Counsel. 29 USC 216 – Penalties
Why the Shifted Burdens Matter to Recovery
The shifts add up. A worker who prevails on a minimum wage or overtime claim is entitled to the full amount of unpaid wages, an equal amount in liquidated damages, and reasonable attorney’s fees and costs paid by the employer.15Office of the Law Revision Counsel. 29 USC 216 – Penalties An employer with inadequate time records, an exemption it cannot substantiate, a willfulness finding that stretches the limitations period to three years, and no viable good faith defense can end up owing multiples of the original unpaid wages. That is the practical stake behind every burden question in an FLSA case.
