Divide your last payroll register by headcount. Now ask what that number would look like multiplied across two years of violations, doubled with liquidated damages, and handed to you as a settlement agreement. For a Calexico freight operation, the answer came to more than $1 million for just 24 warehouse workers — roughly $41,000 per worker, or about 28 times what the Department of Labor recovered per worker on average nationwide last year. If you run a warehouse, a cross-dock, or a trucking outfit with hourly staff, that gap between the average case and a bad one is what makes the details worth your time: the violations behind it are the same ones investigators find in logistics payrolls over and over, and every one of them is fixable before an investigator finds yours.
What happened in Calexico
The Department of Labor's Wage and Hour Division investigated a Calexico, California-based freight and cargo company whose customs-brokerage warehouse workers commuted from Mexico to work at its U.S. warehouse. The investigation found the company had denied 24 workers minimum wage and overtime pay required by the Fair Labor Standards Act. The parties reached a settlement agreement under which the employer pays more than $1 million in back wages and damages, on a payment plan running through December 2026.
Two details from the findings matter more than the headline number. First, the workers were paid in Mexican pesos at rates that translated to as little as $2.03 per hour — far below the federal minimum wage of $7.25, let alone California's much higher state minimum. Second, hours over 40 in a workweek were not paid at the required overtime premium at all. Currency choice and a missing overtime rate turned an underpayment into a seven-figure liability once back wages, damages, and the investigation period compounded.
Nothing about this fact pattern is exotic. It is a small hourly workforce, variable weekly hours, pay practices designed without reference to U.S. wage law, and no overtime computation. That description fits thousands of small logistics operations. The rest of this post is about why investigators keep finding it — and the specific payroll fixes that keep your company out of the next press release.
Why this case is a signal, not an outlier
Start with the enforcement backdrop. In fiscal year 2025, the Wage and Hour Division recovered more than $259 million in back wages for nearly 177,000 workers nationwide — the highest total since 2019, averaging about $1,465 per worker. Overtime violations dominate the docket: roughly $146 million of that total went to more than 110,000 workers shorted on overtime alone, and the Division consistently describes overtime as its most common violation category. When investigators open a logistics payroll, overtime is the first thing they test, because it is the thing employers most often get wrong.
Border-region warehouses are a recurring focus within that trend. In 2023, federal investigators recovered $1.1 million from San Diego-area companies that had paid 50 Mexican workers as little as $2.43 per hour at U.S. warehouses. A 2024 probe of San Diego warehouse and logistics firms recovered nearly $840,000 after finding some workers paid less than $3 per hour. The Calexico recovery extends the same pattern: cross-border commuter workforces, peso-denominated pay scales carried across the border unchanged, and U.S. minimum-wage and overtime rules treated as though they stop at the port of entry. They do not. Work performed on U.S. soil is covered by U.S. wage law, and the Division states plainly that it enforces the law regardless of a worker's immigration status or citizenship.
The takeaway for operators is uncomfortable but simple. If your pay rates were set in another currency, if your overtime line is zero or suspiciously round, or if you assume a category of your workers falls outside wage law, you are standing in the exact spot where these cases start. An internal audit costs an afternoon. The alternative costs years of back pay.
The rules logistics operators get wrong most often
Minimum wage means every hour, in dollars, at the higher rate
The FLSA requires covered employers to pay at least the federal minimum wage — $7.25 per hour — for every hour worked. But federal law is the floor, not the ceiling: where a state sets a higher minimum, as California does, the higher rate controls for work performed there. Three corollaries trip up logistics employers:
- Paying in a foreign currency changes nothing. Convert the pay to dollars per hour and test it against the applicable minimum. A peso wage that looks reasonable in Mexico can land under $3 per hour in California, which is what produces the shocking per-hour figures in these cases.
- Piece rates, day rates, and salaries do not waive the minimum. However you quote pay, total compensation divided by total hours in the week must clear the minimum for each worker.
- Deductions for uniforms, equipment, or shortages cannot drag pay below the minimum. In warehouse and driving operations, charge-backs are a classic way to fall under the line without realizing it.
Overtime at time and one-half after 40 is the default for warehouse staff
Non-exempt employees must be paid at least one and one-half times their regular rate for all hours over 40 in a workweek — whether they are paid hourly, by salary, by day rate, or by piece. In a warehouse, that is nearly everyone: pickers, packers, loaders who do not qualify for a specific exemption, clerks, and most leads.
The regular rate itself is a frequent error source. It is not just the hourly wage; it includes shift differentials, non-discretionary bonuses, and most other compensation for the week, divided by all hours worked. Computing overtime off the base rate while ignoring a weekly production bonus understates the premium every single week.
The Motor Carrier overtime exemption is narrower than trucking assumes
Many trucking and logistics employers assume "transportation workers are exempt from overtime." The actual exemption — Section 13(b)(1) of the FLSA, the Motor Carrier Act exemption — covers only drivers, drivers' helpers, loaders, and mechanics whose duties affect the safe operation of motor vehicles in interstate or foreign commerce, and only when the employer is a qualifying motor carrier or private motor carrier. It exempts those workers from overtime only, never from minimum wage.
Warehouse employees who pick, pack, palletize, and stage freight generally fall outside it. So do dispatchers, office staff, and yard workers whose duties do not affect vehicle safety. Small-vehicle and mixed-duty situations add further limits. If your overtime policy rests on a one-sentence assumption that transportation work is exempt, have employment counsel test each job category against the exemption's actual elements. Misapplied exemptions are among the most expensive payroll errors because they run silently for years across the whole workforce.
Hours worked means all of them
Investigators reconstruct the workweek from every available record — time clocks, gate logs, GPS pings, messages — and the gaps they find are predictable: pre-shift staging and post-shift cleanup off the clock, automatically deducted meal breaks that were worked through, and manual time edits that round down. Each pattern also shows up in payroll data as suspiciously clean clock times and identical 30-minute deductions week after week.
The fix is procedural: capture all time, pay apparent work time rather than scheduled time, require employee sign-off on edits, and keep payroll records for at least three years as the FLSA requires. A timekeeping system proves nothing if its own data shows workers clocking in early and starting unpaid.
Worker classification and flat rates draw scrutiny
Two more logistics staples invite trouble. Classifying drivers or warehouse staff as independent contractors while controlling their schedules, equipment, and routes does not survive DOL or IRS scrutiny, and it layers tax and benefits exposure on top of wage liability. And flat daily or weekly rates without an overtime computation are a standing invitation to an investigation: a flat $180 day that stretches to 12 hours can simultaneously violate minimum wage and overtime once the math is done. If you use flat rates, back them with a weekly hours-and-rate reconciliation that proves the effective rates each week.
Audit your own payroll this month
You do not need an outside firm to run the first pass. Pull one representative month — ideally your busiest recent month, when hours ran longest — and work through these checks:
- Recompute regular rates by hand for five workers. Take each worker's total non-discretionary compensation for a week with overtime, divide by total hours, and multiply by 1.5 to get the required overtime rate. Compare against what payroll actually paid. Any gap is a systemic error, not a one-off.
- Test every pay rate against the highest applicable minimum. Convert any foreign-currency pay to dollars, include the effect of deductions and charge-backs, and test against the state minimum for the work site, not just the $7.25 federal floor.
- List every job title you treat as overtime-exempt and write the exemption next to it. Motor Carrier, executive, administrative, outside sales — each has specific legal elements. Titles with no supportable exemption go back to hourly-plus-overtime.
- Read your timekeeping data like an investigator. Look for auto-deducted breaks, rounded clock times, pre-shift logins, and manual edits without sign-off. Interview two supervisors about off-clock expectations; their answers usually differ from the written policy.
- Verify classification for every 1099 worker under your control. If you set their hours, require your equipment, or bar them from other clients, get a classification review before the next pay cycle.
- Separate overtime premium in your books. If overtime hides inside one wages account, you cannot see trends, budget the true cost of peak weeks, or prove anything quickly in an audit. The bookkeeping pattern below takes minutes to adopt.
Book it so the next audit is boring
Clean books do not prevent violations, but they make violations visible early and audits dramatically cheaper. The habit worth building is granularity: regular wages, overtime premium, employer payroll taxes, and withholdings each get their own account, so a reviewer can trace gross pay to net pay to tax deposits without a spreadsheet reconstruction.
If you keep your books in Beancount, one month-end payroll entry per pay group captures the whole picture. The Beancount documentation covers transaction syntax in full; here is the pattern for a warehouse pay group with $80,000 in regular wages, $12,000 in overtime, $7,000 in employer taxes, and $18,000 withheld:
2026-10-31 * "October warehouse payroll, hourly staff"
Expenses:Payroll:Wages:Regular 80000.00 USD
Expenses:Payroll:Wages:Overtime 12000.00 USD
Expenses:Payroll:Taxes:Employer 7000.00 USD
Liabilities:Payroll:Withholding -18000.00 USD
Liabilities:Payroll:Employer-Taxes -7000.00 USD
Liabilities:Payroll:Net-Payable -74000.00 USDWith overtime isolated in its own account, a monthly trend of Expenses:Payroll:Wages:Overtime against sales or units shipped tells you whether peak-season hours are drifting into violation territory — and a dashboard view in Fava makes that drift visible before quarter-end. Pair each entry with the payroll register as a dated source document, and keep three years of registers alongside the ledger. When an investigator asks how overtime was computed, the answer should be a query, not a memory.
Run the six-step audit above before your next pay cycle, and start with the hand recomputation: five workers, one overtime week, calculator against payroll. If those five tie out, your system is probably sound and you have just bought yourself real confidence. If they do not, you have found the problem on your own schedule — while the fix still costs an afternoon instead of a settlement.
