Is It Illegal to Work Off the Clock?
Is it illegal to work off the clock? For non-exempt employees, yes, in nearly every case. Federal law defines employing someone as suffering or permitting them to work, so if the employer knows or has reason to know the work is happening, it has to be paid, whether it was requested, approved, or even expressly forbidden. That last part surprises most managers: a written policy against off-the-clock work does not make the unpaid time legal. This guide covers what counts, where the narrow exceptions actually sit, what recent guidance changed in 2026, and what both sides should do about it.

The Short Answer
Under the Fair Labor Standards Act, non-exempt employees must be paid for all hours worked. The Department of Labor's Fact Sheet #22 states the rule plainly: the statutory definition of "employ" includes to suffer or permit to work. The implementing regulations at 29 CFR Part 785 go further and say that work not requested but suffered or permitted is work time, using the example of an employee who voluntarily keeps working after their shift ends.
Three consequences follow, and they are the ones people get wrong:
- An employee cannot waive the right to be paid. Agreeing to work unpaid does not make it lawful.
- A policy prohibiting off-the-clock work is not a defense if the employer knew or should have known the work was happening anyway.
- The employer can discipline, but must still pay. Unauthorized overtime can be a performance issue. It is never an excuse to withhold wages for time actually worked.

What Counts as Working Off the Clock
Most off-the-clock work is not dramatic. It is ordinary tasks that happen on either side of a punch:
- Setting up, booting systems, or preparing equipment before clocking in
- Closing, cleaning, cashing out, or securing a site after clocking out
- Working through an unpaid meal break, or being interrupted during one
- Answering calls, texts, and emails after hours
- Taking work home to finish, or logging in from home in the evening
- Attending required meetings or training outside scheduled hours
- Traveling between job sites during the workday
- Correcting mistakes, which the DOL treats as hours worked even when the employee redoes the work voluntarily
- Waiting for work while required to remain on the premises
The DOL's Hours Worked Advisor uses the phrase directly: time spent doing work the employer did not request but allowed is generally hours worked, because the employer knows or has reason to believe the work is continuing and is benefiting from it.
The Legal Standard: Knew or Should Have Known
The test is not whether the employer approved the work. It is whether the employer knew or had reason to believe it was happening. That standard is deliberately broad, and it extends to work performed at home or away from the job site.
In practice, "should have known" is where employers lose. A manager who sees people in the building before their shift starts has reason to know. A supervisor who sends a text at 9pm and gets an answer has reason to know. A system showing a badge swipe at 6:45 for a 7:00 shift has reason to know. Constructive knowledge is enough, and the employer carries the burden of controlling the work if it does not want to pay for it.
State agencies apply the same framework. The Texas Workforce Commission's employment law reference summarizes it as working off the clock never being allowed for non-exempt employees, with the rule extending to work done at home whenever the employer knows or has reason to believe it is being performed.
What Changed in 2026
The Department of Labor issued Opinion Letter FLSA2026-8 on May 28, 2026, addressing pre-shift work at a hospital, and it is the clearest recent statement of where the lines sit.
The DOL concluded that at least some of the pre-shift activities described, including locating work assignments, completing accountability documentation, assigning employees to locations, and receiving handoff reports from colleagues, were integral and indispensable to the employees' principal duties and therefore compensable. It reached the opposite conclusion about time spent waiting in line at the timekeeping station, which it treated as preliminary or postliminary and not compensable, provided it happens before the first principal activity of the day or after the last.
The letter also tightened the practical scope of the de minimis argument. Whether time is de minimis is a fact-specific analysis that weighs the administrative difficulty of recording it against the aggregate amount involved, and the DOL indicated that when compensable pre-shift work happens on a daily basis it is unlikely to qualify. Modern timekeeping systems that already capture the exact clock-in minute invite exacting scrutiny of any de minimis claim, because the "too hard to track" premise no longer holds.
The De Minimis Exception, and Why It Keeps Shrinking
The regulation at 29 CFR 785.47 allows employers to disregard insubstantial or insignificant periods beyond scheduled hours that cannot as a practical matter be precisely recorded. Courts have called these trifles.
Two limits matter. First, the regulation explicitly rejects using the rule to cover employees who regularly report a few minutes early or stay a few minutes late. Regular is the operative word: a recurring pattern is not a trifle. Second, the administrative difficulty prong has been eroded by technology. When a system already logs the minute, arguing that the minute was impossible to capture is a difficult position.
Some states go further and reject the federal de minimis doctrine outright for state law claims, which means small increments of daily unpaid time can be fully compensable even where a federal court might have excused them.
Remote Work and After-Hours Messages
The FLSA applies identically to a kitchen table and a cubicle. There is no remote-work carve-out in Part 785, and suffered-or-permitted work is paid work wherever it happens.
The DOL's Field Assistance Bulletin 2020-5 set the operating standard for telework: employers must exercise reasonable diligence to track hours worked remotely, and establishing a clear reporting procedure that employees know how to use generally satisfies that duty. The standard turns on what the employer should have known rather than everything it theoretically could have discovered, which places part of the burden on employees to report their time through the process provided.
The practical implication for managers: if you have a reporting system, enforce it and pay what gets reported. If you ignore reports, discourage them, or route work around the system by messaging people after hours, the reasonable diligence defense collapses.
Meal Breaks, Rounding, and Automatic Deductions
Three mechanics cause most of the unintentional violations.
Meal breaks. An unpaid break generally requires the employee to be completely relieved of duty. Eating at a desk while covering the phone, or a break interrupted twice by questions, is working time. Many states add their own meal and rest break rules on top of the federal baseline.
Rounding. Under 29 CFR 785.48(b), rounding is generally permissible when it is neutral on its face and averages out over time so employees are fully compensated for the time actually worked. A policy that rounds in both directions and washes out across pay periods is usually defensible. One that always rounds down, or rounds start times up and end times down, is not.
Automatic meal deductions. Systems that subtract thirty minutes regardless of what happened are the single most common source of off-the-clock claims. If you use one, you need a working, used, and honored mechanism for employees to cancel the deduction on days they worked through.
Does This Apply to Salaried Employees?
It depends on exemption status rather than on being paid a salary. Properly classified exempt employees are paid for the job rather than by the hour, so answering email at night does not generate additional pay, though improper deductions from their salary can jeopardize the exemption.
The bigger issue is misclassification. Salaried does not mean exempt. If an employee is salaried but does not actually meet the duties and salary tests for an exemption, they are non-exempt, all the off-the-clock rules apply, and the unpaid overtime can accumulate for years before anyone notices.
Employer Checklist to Stay Compliant
- Write a clear policy requiring all time worked to be recorded, and enforce it in both directions
- Train supervisors that "we don't approve overtime" is not a reason to withhold pay for hours worked
- Give employees a simple way to report time worked outside the schedule, including from home
- Stop automatic meal deductions unless employees can reliably cancel them
- Audit your rounding policy for neutrality over a full quarter, not a single week
- Set expectations about after-hours calls, texts, and email for non-exempt staff
- Pay first, then address unauthorized work as a performance matter
- Keep accurate time records; when employer records are inadequate, courts allow employees to prove hours by reasonable inference
- Review exemption classifications against actual duties, not job titles
What Employees Can Do
Keep your own contemporaneous record. A simple log of start and end times, missed breaks, and after-hours messages is persuasive, and it matters most when the employer's own records are incomplete. Under longstanding Supreme Court precedent, when an employer fails to keep adequate records, an employee may carry the burden by showing the amount of work as a matter of just and reasonable inference, which shifts the burden to the employer to rebut it.
Raise it internally first if you can, in writing, so there is a record of the employer being told. If that does not work, the Wage and Hour Division accepts complaints, and filing is free. The FLSA prohibits retaliation against employees who complain about wage violations, whether the complaint goes to the agency or to the employer.
On timing, FLSA claims generally must be brought within two years, extended to three years for willful violations. Successful claims frequently include liquidated damages equal to the unpaid wages, effectively doubling recovery, and state law may provide additional penalties on top. Waiting costs money, because the oldest weeks drop off the back end as time passes.
Common Mistakes
- Relying on a no-off-the-clock policy. The policy helps only if it is enforced. Knowledge of the work overrides the rule on paper.
- Treating small increments as free. Fifteen minutes a day at $21 an hour is over $1,300 a year per employee, before any overtime or damages.
- Asking employees to clock out and finish up. This is the clearest possible violation, and it is usually documented by the timestamps themselves.
- Automatic meal deductions with no override. The deduction runs whether or not the break happened.
- Texting non-exempt staff after hours. Routine after-hours responses are compensable work, and the message log proves the employer knew.
- Assuming salaried means exempt. Misclassification converts every late night into unpaid overtime liability.
- Letting the timekeeping system round only one way. Neutral rounding is defensible; systematic rounding down is not.
Where a System Helps
None of this requires software. It requires that every hour worked gets recorded and paid, which some businesses manage on paper.
What matters in any tool you use: employees able to record time wherever the work happens rather than only at a terminal, a record of scheduled versus actual hours so early starts and late finishes are visible instead of invisible, overtime calculated automatically rather than by hand, and records you can produce two or three years later if anyone asks.
In Updoot, hours are tracked from desktop, mobile, or a kiosk against a job, project, and location, with a live view of who is clocked in, so time worked away from a fixed terminal still lands in the record. Overtime is calculated automatically, and payroll reports compile all hours worked in a payroll-ready format with a retained history, which is the part that matters when a question arrives long after the pay period closed.
Frequently Asked Questions
For non-exempt employees, yes. The FLSA defines employing someone as suffering or permitting them to work, and 29 CFR Part 785 states that work not requested but suffered or permitted is work time. If the employer knows or has reason to believe the work is happening, it must be paid, even if it was never approved and even if company policy prohibits it. Employees cannot waive the right to be paid for hours actually worked.
No. An employer may discipline an employee for working hours that were not authorized, but it still has to pay for the time worked. Withholding wages as a penalty for breaking an overtime rule is itself a violation. The correct sequence is to pay the hours, then address the unauthorized work as a performance issue.
Often yes. The de minimis rule at 29 CFR 785.47 covers only insubstantial periods that cannot practically be recorded, and the regulation rejects using it for employees who regularly start early or stay late. In Opinion Letter FLSA2026-8, the DOL said pre-shift work occurring daily is unlikely to be de minimis, and that modern timekeeping systems capturing exact clock-in times invite exacting scrutiny of such claims. Whether a specific pre-shift task counts turns on whether it is integral and indispensable to the job.
For non-exempt employees, yes, when it amounts to work the employer knows or should know about. There is no remote-work exception in the hours worked regulations. The DOL's Field Assistance Bulletin 2020-5 requires employers to exercise reasonable diligence in tracking telework hours, which usually means providing a reporting procedure. Employers that message staff after hours and accept the responses have a difficult time arguing they did not know.
FLSA claims generally reach back two years from filing, extended to three years for willful violations. Successful claims often include liquidated damages equal to the amount of unpaid wages, and some states allow longer lookback periods or additional penalties. Because the window moves forward over time, delay reduces what can be recovered.
It depends on whether they are exempt. Properly classified exempt employees are paid for the job rather than the hour, so extra hours do not generate extra pay, though improper salary deductions can endanger the exemption. Salaried does not automatically mean exempt: an employee who fails the duties or salary tests is non-exempt, and all the off-the-clock and overtime rules apply to them.
Final Takeaway
If a non-exempt employee is working, the clock should be running. The employer's knowledge is what triggers the obligation, not its approval, so the fix is never a stricter policy on paper. It is making sure the work that happens is the work that gets recorded: a reporting route employees actually use, no automatic deductions that run unchecked, rounding that goes both ways, and managers who understand that paying for unauthorized time and addressing it afterward are two separate steps in that order.
