Workers prove unpaid overtime by showing they performed unpaid work and providing enough evidence for the court to infer the amount and extent. That proof often combines personal logs, pay records, and digital timestamps, according to Nichols Kaster PLLP in its guide to overtime evidence. A wage and hour lawsuit is a worker claim that an employer broke pay rules such as overtime. Nonexempt means the worker is covered by those overtime rules.

What the overtime rule protects
Covered nonexempt workers must receive overtime at not less than 1.5 times their regular rate for hours over 40 in a workweek. Cornell Law School Legal Information Institute states that rule from FLSA Section 7 in the federal overtime statute. Every covered employer must keep records for nonexempt workers, according to U.S.
Department of Labor Fact Sheet #21. Those records include identifying information, hours worked each day, total hours each workweek, pay basis, and wages earned. Those employer records matter because they set the baseline. When they are missing or wrong, a worker comparison file becomes more important.
Who must prove what
A worker first must prove that uncompensated work was performed. The worker also must offer sufficient evidence of amount and extent as a just and reasonable inference, under Anderson v. Mt. Clemens Pottery. Once the worker makes that showing, the burden shifts to the employer, according to the U.S.
Supreme Court via OpenJurist in the Anderson overtime decision. The employer then must produce precise records or negate the inference. If it does not, the court may award approximate damages. This framework helps workers even without perfect timecards. Estimates can support recovery when they are reasonable and the employer lacks contrary proof.
Which evidence carries weight
Strong proof combines several independent sources rather than memory alone. Useful items include personal time logs, pay stubs, work schedules, badge or GPS or computer logs, emails or texts with timestamps showing off-hours work, and coworker testimony. Each item answers a different question. Logs show claimed hours.
Pay stubs and schedules show paid hours. Electronic entries and messages place the worker on duty at a specific time. Coworker testimony can corroborate routines or shared schedules. Together, the pieces let a court infer unpaid time with confidence.
How to build a comparison file
Save contemporaneous logs and messages, then compare them to employer records. Nichols Kaster PLLP reports this practical approach because inadequate employer records let workers rely on estimates and inferences.
A simple file is easier to use than a large pile: Keep copies outside work systems. Contemporaneous notes usually carry more weight than later reconstructions.
- write start, stop, break, and task notes each workday
- save schedules, pay stubs, and time edits in one place
- keep timestamped emails, texts, and system logins
- note witness names for regular overtime routines
What limits your claim
Claims for unpaid overtime or liquidated damages must be filed within 2 years. Cornell Law School Legal Information Institute states the deadline from 29 U.S.C. Section 255 in the federal wage-claim time-limit law. The period extends to 3 years only for willful violations.
Employers who violate overtime rules are also liable for unpaid overtime plus an equal additional amount as liquidated damages, plus attorney fees and costs, according to Cornell Law School Legal Information Institute in 29 U.S.C. Section 216. So late claims can lose older weeks. Compare your logs to pay stubs now and keep copies outside work.
