A $1.7 million overtime mistake, and why bonus season is when manufacturers get this wrong

The U.S. Department of Labor's Wage and Hour Division announced it recovered $1,730,598 in back wages for 1,666 hourly employees of The State Group Industrial (USA) Ltd. Inc., a multi-trade contractor working at Ford Motor Co.'s electric vehicle and battery manufacturing campus in Stanton, Tennessee. Investigators found the company violated the Fair Labor Standards Act by leaving incentive bonuses out of the regular rate of pay used to calculate overtime, shorting employees the full overtime premium owed on every hour worked past 40 in a workweek. (U.S. Department of Labor) The case was still showing up in employer-side compliance roundups this month, a sign that the underlying mistake is common enough to keep circulating as a cautionary example.

The rule that trips people up

Under the FLSA, overtime is not simply 1.5 times an employee's base hourly rate. It is 1.5 times the "regular rate of pay," and that regular rate has to include most non-discretionary bonuses, the kind tied to production, attendance, safety, or performance goals rather than a surprise gift at the holiday party. The Department's own fact sheet spells this out, and it is the exact provision the Stanton contractor got wrong. (DOL Fact Sheet 56C) In this case, the shortfall averaged a bit over $1,000 per employee, small on any single paycheck but large once multiplied across 1,666 people and however many pay periods the violation ran.

Manufacturing is a common place for this to happen because bonus structures there are often layered on top of an hourly base, think shift differentials, production incentives, perfect-attendance pay, or safety bonuses. Each of those, if it is announced in advance and tied to a measurable goal, is generally non-discretionary and has to be folded into that week's regular rate before the overtime multiplier is applied. A flat 1.5x on the base hourly rate alone, with the bonus paid separately and never revisited, is the mistake that keeps showing up in DOL enforcement actions.

What this looks like in practice

Say a production employee earns $22 an hour and works 45 hours in a week that also includes a $100 weekly production bonus. The regular rate is not just $22. You add the $100 bonus into the week's total straight-time pay, divide by 45 hours, and that becomes the regular rate the overtime premium is built on. Skip that step and the employee is underpaid on every overtime hour that week, even though the base rate and the bonus were both technically paid.

The Department also pointed employers toward two recent opinion letters on which payments must be folded into the regular rate, one from 2025 and one issued this year, plus its PAID self-audit program, which lets employers who find their own mistakes report and resolve them before an investigation starts. (DOL Opinion Letter FLSA2026-2) That self-audit path is worth knowing about if a payroll review turns up a similar gap, since it tends to be a far less costly route than waiting for an investigator to find it first.

A quick gut check for your own bonus programs

If you run payroll or HR for hourly employees who also get bonuses, a few questions are worth asking this week, especially if mid-year or summer production incentives are about to go out. Is the bonus non-discretionary, meaning it was promised in advance and tied to a specific goal rather than handed out purely at management's discretion? If so, is it being added back into the regular rate for any week in which the recipient also worked overtime? And is your payroll system actually doing that recalculation automatically, or is it a manual step someone has to remember every pay period? A lot of these violations are not intentional, they are a payroll setup that never accounted for the interaction between bonus pay and overtime in the first place.

None of this applies to genuinely discretionary bonuses, the kind not promised ahead of time and not tied to a specific metric, those can stay outside the regular rate. The line between the two categories is where most of the real disputes live, and it is fact-specific enough that a close call is worth running past employment counsel or the Wage and Hour Division's compliance helpline rather than guessing.

This is general information about a public enforcement action and federal wage law, not legal advice. Every payroll setup is different, and wage and hour rules vary by state on top of the federal floor, so if this raises a question about your own bonus program, talk to employment counsel or your state labor agency before making changes.
