In a decision of significant consequence for Wisconsin employers, the U.S. Court of Appeals for the Seventh Circuit has clarified how shift differentials, incentive premiums, and holiday pay should be treated when calculating overtime under both federal and state law. The ruling in Lutz v. Froedtert Health Inc., decided July 27, 2026, provides a welcome measure of predictability for employers who have long navigated overlapping obligations under the federal Fair Labor Standards Act (FLSA) and Wisconsin's Wage Payment and Collection Law.
At the center of the case was a Wisconsin health system's methodology for computing overtime pay for hourly employees. The employer included shift differentials, weekend differentials, and incentive premiums in the employees' regular rate before applying a half-time overtime multiplier. The Seventh Circuit held that this practice satisfied both the FLSA and Wisconsin's wage statute, confirming that these forms of additional compensation must be incorporated into the regular rate rather than treated as stand-alone payments outside the overtime calculation.
The court also addressed the treatment of holiday pay premiums, concluding that the employer properly excluded those premiums from the regular-rate calculation because they exceeded 1.5 times the employees' base hourly rates. That conclusion aligns with well-established FLSA exclusions and confirms that Wisconsin law follows the same approach when a qualifying premium is paid for work performed on designated holidays.
Perhaps most significant is the broader signal the decision sends: Wisconsin courts and regulators should apply FLSA standards when analyzing state overtime obligations. For multistate employers and those headquartered in Wisconsin, this consistency reduces the risk that identical pay practices will be judged differently under federal and state frameworks. It also provides a clearer roadmap for auditing existing compensation structures, drafting policies covering premium pay, and defending against regular-rate miscalculation claims, which continue to be a frequent source of wage-and-hour litigation.
Employers should take this opportunity to review shift differential formulas, incentive plans, and holiday pay policies to confirm alignment with the framework endorsed in Lutz. Small structural adjustments can meaningfully reduce exposure while preserving the flexibility employers need to attract and retain talent.
