FMLA Eligibility: Do ‘Bonus Hours’ Count Toward the 1,250?

FMLA eligibility usually looks straightforward: Employees need 1,250 hours of service in the prior 12 months. But the calculation isn’t always that simple, especially when bonus pay or shift differentials come into play.

This well-established Sixth Circuit precedent – Mutchler v. Dunlap Memorial Hospital – shows how “hours worked” questions can end up in court. Those disputes can still lead to U.S. Department of Labor investigations, making precise hours tracking non-negotiable.

FMLA Eligibility: What Counts Toward 1,250 Hours

In Mutchler, registered nurse Carla Mutchler sought FMLA leave for carpal tunnel surgery on both wrists but had worked only 1,242.8 hours in her 12-month lookback period. She argued “bonus hours” – extra pay under the hospital’s weekend program, which paid nurses for 68 hours when they worked 48 scheduled hours over two weeks – should count toward the threshold.

The employer initially approved her first leave request but later told her she wasn’t eligible for additional FMLA leave. When she returned after her second surgery, the hospital had given her weekend position to another nurse and scheduled her for weekdays.

She then sued, claiming the hospital violated the FMLA. A district court granted summary judgment to the hospital, and Mutchler appealed to the Sixth Circuit.

Why Appeals Court Backs Employer

The Sixth Circuit affirmed summary judgment for the employer on two fronts:

• Hours strictly per FLSA principles: FMLA “hours of service” follow Fair Labor Standards Act hours-worked principles. See 29 CFR § 825.110(c) and 29 CFR Part 785. They include only time the employee is required to give the employer or is suffered or permitted to work. Bonus pay tied to hours – even if labeled as such – doesn’t add to the tally unless actual work occurred. Mutchler’s weekend bonus hours were an incentive, not pay for extra hours worked.
• No equitable estoppel: The employer first OK’d her leave and treated it as FMLA leave, but HR told her she didn’t qualify for more FMLA leave before she scheduled her second surgery. She argued DOL rules barred the hospital from reversing its eligibility decision. The court said that rule didn’t apply, since the hospital protected the first leave and her original request didn’t cover the second surgery. It also said common-law estoppel wouldn’t apply. She had to prove the hospital misled her, and she reasonably relied on it to her detriment, which the facts didn’t show.

The following do not count toward the 1,250-hour requirement:

• Paid leave, including vacation, sick time or holidays, even if it runs concurrently with FMLA leave
• Unpaid FMLA leave, including prior FMLA leave
• Bonus pay for hours not actually worked, such as the weekend incentive hours in Mutchler
• On-call time, unless the employee is “engaged to wait”

HR Compliance Takeaways

Because eligibility hinges on a 1,250-hour calculation, small errors can create significant exposure. This ruling reinforces where HR processes must be precise to prevent disputes and defend decisions.

• Track eligibility precisely. Audit FLSA-qualifying hours monthly during the 12-month lookback, reconcile payroll reports against timekeeping data, and flag employees nearing 1,250 hours. Part-timers picking up shifts are high-risk for miscalculations, especially when bonus pay is involved.
• Document the calculation. Retain the 12-month hours worksheet or payroll report used to determine FMLA eligibility in the leave file so you can show the calculation.
• Issue eligibility notices without delay. Provide the required notice within five business days of a leave request, and follow up in writing if the initial determination changes.
• Clarify pay versus hours. Train managers and payroll staff that shift differentials, bonuses and premiums don’t add hours toward the 1,250-hour FMLA eligibility requirement. Only hours actually worked count.
• Review state overlays. Confirm whether state family or medical leave laws apply lower hour thresholds or broader eligibility rules.

Payroll configurations deserve the same scrutiny as time records. Eligibility totals depend on how pay codes are structured and how reports pull data. A scheduled review of system settings and calculation logic helps catch misclassifications before they affect a leave decision.

FMLA eligibility ultimately comes down to the numbers. When timekeeping data, payroll classifications and eligibility notices align, employers are better positioned to withstand DOL scrutiny or litigation.
