Processing an FMLA Leave Request: A Practical Checklist

42 U.S.C. § 2000

Type: Checklist
Jurisdiction: National
Date: 2025-03-08
Topic: Labor and Employment

A step-by-step administrative workflow for handling an FMLA leave request from the moment an employee mentions a problem through return to work, exhaustion, or termination. It is organized around the two five-business-day notice clocks and the certification process, because that is where FMLA liability is actually created. It covers coverage and eligibility calculation including the remote-worksite trap, opening one file per qualifying reason, the eligibility notice, the certification request with essential job functions and GINA safe-harbor language, reviewing and curing deficient certifications, authentication and clarification limits, second and third opinions, the designation notice, absence tracking in correct increments, exclusion of protected absences from attendance and bonus programs, six-month recertification, the honest-belief investigation, fitness-for-duty and restoration, the handoff to the ADA interactive process at exhaustion, recordkeeping, and the state paid-leave overlay. A worked example follows a fictional manufacturer through a dual-reason request involving a parent's illness and chronic migraines. Educational, not legal advice.

Processing an FMLA Leave Request: A Practical Checklist

Labor and Employment > Leave Law | Published 8 March 2025 - Updated 12 June 2026 | UpLaw - uplaw.us

FMLA cases are almost never about whether the employee was sick. They are about whether a form went out within five business days, whether a supervisor called a doctor, and whether protected absences were counted against an attendance policy. This checklist is the paperwork that prevents the lawsuit.

Keywords: FMLA administration, WH-381, WH-382, eligibility notice, designation notice, medical certification, GINA safe harbor, intermittent leave tracking, recertification, fitness for duty, restoration, ADA handoff, state paid family leave

Work this checklist top to bottom for every leave request, even the obvious ones. The doctrinal background is in Family and Medical Leave Law: A Comprehensive Guide to the FMLA and State Paid Leave; the litigation-risk framing is in Administering FMLA Leave Without Getting Sued: Interference, Retaliation, and the Certification Trap.

Two structural rules before you begin.

Centralize. Leave administration belongs to HR or a trained leave administrator, never to operating supervisors. A supervisor's entire FMLA job is one instruction: tell HR the same day.

Two clocks. The Notice of Eligibility and Rights and Responsibilities is due within five business days of the request or of the employer's knowledge that leave may be qualifying. The Designation Notice is due within five business days of having enough information to decide. Put both on the calendar the day intake happens. 29 C.F.R. § 825.300.

Our running example. Ironwood Fabrication, Inc. (fictional) has 240 employees at three plants plus eleven remote engineers. Dana Reyes is a shift lead at the Ashford plant with six years of service. Dana mentions two things to the plant manager on a Tuesday: a mother recently diagnosed with a serious illness, and migraines that sometimes make a shift impossible.

Phase 1 — Intake (day of)

[ ] Log the date, time, who received the information, and what was said, verbatim where possible.
[ ] Route to HR or the leave administrator the same day.
[ ] Do not require the employee to say "FMLA." Enough information that leave may be qualifying triggers the employer's obligations.
[ ] Note whether the leave is foreseeable (30 days' notice expected) or unforeseeable (notice as soon as practicable).
[ ] Confirm the employee followed the usual call-in procedure; if not, document the deviation but do not treat it as a waiver without checking the unusual-circumstances exception.
[ ] Start the five-business-day eligibility notice clock.

Why it matters, and the traps. The employer's obligations begin when any management-level employee acquires knowledge that leave may be qualifying — not when a form is filled out and not when the letters "FMLA" are used. The most common structural failure in FMLA practice is that a supervisor absorbs the information, handles the absence informally, and HR learns about it three months later when discipline is proposed. By then the notice clocks have long expired and the file shows nothing.

Train supervisors to route, not evaluate. A supervisor who assesses whether a condition is "serious enough," questions the employee about a diagnosis, or expresses frustration in writing creates the plaintiff's best exhibit — and may face individual liability, since the FMLA's definition of employer reaches persons acting in the employer's interest. See Haybarger v. Lawrence County Adult Probation & Parole, 667 F.3d 408 (3d Cir. 2012).

Ironwood. The plant manager emails HR the same afternoon with a short factual summary and no commentary. That email is the best document in the file.

Phase 2 — Coverage and eligibility

[ ] Confirm the employer is covered: 50+ employees for 20+ workweeks in the current or preceding calendar year.
[ ] Confirm 12 months of employment (need not be consecutive).
[ ] Calculate 1,250 hours actually worked in the preceding 12 months from timekeeping records — excluding paid vacation, holidays, paid sick leave, and prior FMLA leave.
[ ] Confirm 50 employees within 75 miles of the employee's worksite, measured in surface miles over public roads, as of the date notice was given.
[ ] For employees with no fixed worksite — remote workers, travelers — identify the site from which work is assigned or to which the employee reports, and count there.
[ ] Check for joint employment (staffing agency, PEO) and identify the primary employer.
[ ] Check for integrated employer aggregation across affiliated entities.
[ ] If the employee is ineligible, say so in the notice, promptly and in writing, with the reason.

Why it matters, and the traps. Coverage and eligibility are separate questions, and a covered employer can have entirely ineligible worksites. Two specific traps:

The remote-worker trap. A fully remote employee is assigned to the worksite from which work is assigned, not to their kitchen. 29 C.F.R. § 825.111(a)(2). Employers routinely assume remote workers are ineligible because no colleague is within 500 miles. They are usually eligible.

The estoppel trap. An employer that grants FMLA leave to an ineligible employee, then tries to withdraw the designation, may be estopped. Calculate before you designate, and if you get it wrong, get advice before reversing.

Ironwood. Ashford has 140 employees — eligible. (Corriston, with 38 employees and no other facility within 75 miles, has no eligible employees at all, a fact Ironwood's handbook must reflect.) Dana has six years and 1,904 hours. Eligible.

Phase 3 — Identify each qualifying reason and open a file for each

[ ] Identify every qualifying reason presented. Do not merge them.
[ ] Match each to a statutory category: birth/bonding; adoption or foster placement; care for a spouse, child, or parent with a serious health condition; the employee's own serious health condition; qualifying exigency; military caregiver.
[ ] Verify the covered relationship. Spouse uses the place-of-celebration rule; "child" means under 18 or 18+ and incapable of self-care due to disability; "parent" excludes parents-in-law; consider in loco parentis in both directions.
[ ] Determine whether the condition meets serious health condition by mapping facts onto the regulatory categories — inpatient care, or three-days-plus-treatment, pregnancy, chronic, permanent/long-term, or multiple treatments. 29 C.F.R. §§ 825.113–825.115.
[ ] Determine the expected form: continuous, intermittent, or reduced schedule.
[ ] Open a separate leave file and certification track for each reason.

Why it matters, and the traps. Two distinct qualifying reasons need two certifications from two providers, and merging them produces a file that cannot support later decisions. Also: do not evaluate a serious health condition by whether the diagnosis sounds grave. Migraine is the paradigm chronic condition, and the chronic category has no three-day incapacity requirement — a single day qualifies if certified. Employers that deny intermittent leave because "a headache isn't serious" lose.

Ironwood. Two files opened: (A) care for a parent with a serious health condition, likely continuous or intermittent; (B) Dana's own chronic condition, intermittent.

Phase 4 — Eligibility notice, within five business days

[ ] Issue the Notice of Eligibility and Rights and Responsibilities — DOL Form WH-381 — within five business days.
[ ] State eligibility, or ineligibility with the reason.
[ ] State the certification requirement and the 15-calendar-day return deadline, and the consequence of failure.
[ ] State whether paid leave will be substituted and run concurrently.
[ ] State the premium payment arrangement and the consequence of nonpayment.
[ ] State the applicable 12-month measurement method.
[ ] State any fitness-for-duty certification requirement.
[ ] State key employee designation if applicable (rare).
[ ] Deliver by a method that produces proof, and save it to the file.

Why it matters, and the traps. WH-381 is free, takes minutes, and disposes of most later process arguments. Failing to send it does not create automatic liability — Ragsdale v. Wolverine World Wide, Inc., 535 U.S. 81 (2002), requires that a violation cause actual prejudice — but it removes the employer's best evidence and hands the plaintiff a clean interference theory that costs a summary judgment motion to defeat.

The fitness-for-duty item matters more than it looks: the employer may only require it if the requirement was stated in the notice. Employers that require a return-to-work certification without having announced it have violated the regulation and cannot lawfully delay reinstatement over it.

Phase 5 — Request certification the right way

[ ] Use the correct DOL form: WH-380-E (employee's own condition), WH-380-F (family member), WH-384 (qualifying exigency), WH-385 / WH-385-V (military caregiver).
[ ] Request in writing and allow at least 15 calendar days.
[ ] Attach a written statement of the employee's essential job functions and ask whether the employee can perform them.
[ ] Include the GINA safe-harbor language directing the provider not to provide genetic information including family medical history. 29 C.F.R. § 1635.8(b)(1)(i)(B).
[ ] For intermittent leave, ensure the form calls for expected frequency and duration of episodes.
[ ] Do not request a diagnosis as such, and do not ask for more than the form requires.
[ ] Calendar the 15-day deadline and a follow-up at day 12.

Why it matters, and the traps. The essential-functions attachment is the cheapest available improvement to certification quality and almost nobody does it. Without it, providers answer in generalities and the employer cannot manage anything.

The GINA safe harbor prevents a problem the employer never intended to create: a certification request that elicits family medical history can support an inadvertent-acquisition claim under Title II of GINA, 42 U.S.C. § 2000ff. The safe-harbor paragraph is three sentences and eliminates the issue.

For intermittent leave, the certified frequency is the yardstick for every later absence and every later disciplinary decision. A certification that says only "as needed" gives the employer nothing to manage against — send it back for clarification.

Ironwood. Two certification requests go out with the eligibility notice, each with Dana's essential functions attached and the GINA paragraph included. The migraine form asks for expected frequency and duration.

Phase 6 — Review the certification; cure, authenticate, clarify

[ ] Determine whether the certification is complete (all applicable entries filled) and sufficient (entries responsive and not vague).
[ ] If deficient, state in writing exactly what is missing and allow at least seven calendar days to cure.
[ ] For authentication (did this provider complete it?) or clarification (what does this mean?), contact the provider only through a health care provider, HR professional, leave administrator, or management official — never the employee's direct supervisor. 29 C.F.R. § 825.307(a).
[ ] Ask no additional questions beyond the form's contents.
[ ] Obtain the employee's HIPAA authorization if the provider requires it; if the employee refuses, leave may be denied for insufficient certification.
[ ] If you have reason to doubt validity, document the basis, then obtain a second opinion at employer expense from a provider not employed on a regular basis by the employer.
[ ] If first and second conflict, obtain a binding third opinion from a jointly approved provider, also at employer expense.
[ ] Treat the employee as provisionally FMLA-protected while second or third opinions are pending.
[ ] Store all medical documents in a separate confidential file, not the personnel file.

Why it matters, and the traps. The supervisor phone call is the single most damaging avoidable error in FMLA administration. A well-meaning manager who calls the doctor's office to ask "how bad is it really?" creates a per se regulatory violation, a privacy problem, and an exhibit that will be read to a jury. Write the rule down: only the leave administrator contacts providers, and only to authenticate or clarify.

Two limits to remember: second opinions are available for initial certifications only, not recertifications; and "reason to doubt" requires an articulable basis, which should be documented before the request, not reconstructed afterward.

Ironwood. The neurologist's frequency estimate is illegible. The leave administrator calls to clarify — proper. Separately, the frustrated plant manager emails the neurologist asking whether Dana "really can't work with a headache." That email is a violation, is discoverable, and is the case. It happens because nobody told the plant manager the rule.

Phase 7 — Designation notice, within five business days

[ ] Issue the Designation Notice — DOL Form WH-382 — within five business days of having enough information.
[ ] State whether the leave is designated as FMLA-qualifying.
[ ] State the amount counted against the entitlement, if known; if not known because leave is intermittent, say so and provide the amount on request (no more often than every 30 days).
[ ] Restate any fitness-for-duty requirement.
[ ] Issue a separate designation for each qualifying reason.
[ ] If leave is denied, state the reason clearly.
[ ] Designate promptly rather than deferring; the employer, not the employee, controls designation. DOL Opinion Letter FMLA2019-1-A (Mar. 14, 2019).

Why it matters, and the traps. Employers sometimes delay designation to "let the employee use vacation first and save the FMLA." The Department's position is that this is unlawful — qualifying leave must be designated, and the entitlement cannot be banked. Some circuit authority is more permissive about an employee affirmatively declining FMLA (see Escriba v. Foster Poultry Farms, Inc., 743 F.3d 1236 (9th Cir. 2014)), but the conservative practice is to designate and separately document the employee's stated preference.

Phase 8 — Set up tracking and pay/benefit mechanics

[ ] Record the entitlement balance under the employer's chosen 12-month method (rolling backward is the recommended default).
[ ] Set the increment: the smallest increment used for other leave, and never more than one hour. 29 C.F.R. § 825.205.
[ ] Configure substitution of paid leave to run concurrently, consistent with the policy's own terms.
[ ] Confirm coordination with short-term disability and workers' compensation — paid leave generally cannot be required to be substituted for a period covered by such benefits.
[ ] Confirm group health coverage continues on the same terms, and communicate the premium arrangement.
[ ] Exclude protected absences from any no-fault attendance or occurrence-point system.
[ ] Audit bonus, incentive, and perfect-attendance programs — FMLA absence may only affect them if equivalent non-FMLA leave is treated the same. § 825.215(c)(2).
[ ] Confirm exempt employees' salary-basis status is not disturbed by partial-day unpaid FMLA leave. § 825.206.
[ ] Flag the file for state PFML and state/local sick leave evaluation (Phase 13).

Why it matters, and the traps. The attendance-system integration is the highest-frequency source of interference liability in the entire statute, because attendance systems are usually automated and nobody reconfigures them. If protected absences accrue points, the system generates the violation on a schedule without any human deciding anything.

The increment rule catches employers that dock other leave in fifteen-minute units but count FMLA in half-days. And check perfect-attendance awards: they are small in dollars and reliably litigated.

Phase 9 — Manage the leave while it runs

[ ] Log each intermittent absence against the correct certification and compare to the certified frequency.
[ ] Tell the employee contemporaneously which absences are protected and which are not.
[ ] Request periodic status reports on intent to return — reasonable in frequency, limited in content.
[ ] Do not ask the employee to perform work during leave.
[ ] Apply any outside-employment policy only if it is uniform and pre-existing.
[ ] For foreseeable intermittent leave based on planned treatment, consider temporary transfer to an equivalent-pay position that better accommodates the schedule. § 825.204.
[ ] Track the running balance and notify the employee as exhaustion approaches — in writing, with the ADA handoff flagged.

Why it matters, and the traps. Telling the employee in real time which absences were protected is not required by the regulation, and it is the practice that most reliably defeats a later claim that discipline was based on protected leave. It converts a disputed question into a documented, uncontested record.

Temporary transfer is available only for planned treatment. It cannot be used to move an employee with unpredictable flare-ups, and using it that way is itself interference.

Phase 10 — Recertification

[ ] Recertify no more often than every 30 days in connection with an absence, subject to the rules below.
[ ] Where the certification states a duration longer than 30 days, wait for that period — but in all cases you may recertify every six months in connection with an absence. 29 C.F.R. § 825.308.
[ ] Recertify earlier if circumstances change significantly, if information casts doubt on the stated reason or continuing validity, or if the employee requests an extension.
[ ] Allow 15 calendar days for return.
[ ] Require a new certification each leave year for conditions extending beyond it. § 825.305(e).
[ ] Remember: no second opinion on a recertification.

Why it matters, and the traps. The six-month recertification right is the most underused control in the statute. A certification supporting "two to three days per month," written three years ago and never revisited, is not a management system — it is an open-ended entitlement the employer granted itself. Calendar recertification for every open intermittent file.

Phase 11 — Suspected abuse

[ ] Route the concern to HR; do not let the supervisor investigate or contact the provider.
[ ] Identify the specific factual basis — pattern analysis (Mondays and Fridays), inconsistent statements, third-party reports, absences exceeding the certified frequency.
[ ] Consider recertification first; it is the cheapest and least inflammatory tool.
[ ] If investigating, do so uniformly and document the trigger, steps, and findings. See Conducting a Workplace Investigation: A Practical Checklist.
[ ] Use surveillance or social media review only with counsel's involvement and a documented, legitimate basis.
[ ] Base any discipline on an honest, reasonably grounded belief of misuse, and document the reasoning.
[ ] Confirm the same standard has been applied to other employees.

Why it matters, and the traps. Employers are not required to be passive about intermittent-leave abuse. Where the employer holds an honest, reasonably grounded belief that leave was misused, discipline is generally lawful even if the belief proves mistaken. Vail v. Raybestos Products Co., 533 F.3d 904 (7th Cir. 2008). But selective investigation is itself a retaliation theory: investigating the one employee whose absences annoy a supervisor, while ignoring identical patterns elsewhere, converts a defensible decision into a jury question.

Phase 12 — Return, restoration, and exhaustion

[ ] Require a fitness-for-duty certification only if it was stated in the designation notice, applied uniformly, and limited to the condition for which leave was taken. § 825.312.
[ ] For intermittent leave, request fitness-for-duty no more than once every 30 days and only where reasonable safety concerns exist.
[ ] Restore to the same or an equivalent position: substantially similar duties, skill, effort, responsibility, and authority; same or equivalent shift; same or geographically proximate worksite; equivalent pay, benefits, bonus and overtime opportunity, and advancement prospects.
[ ] If restoration is denied because the position was eliminated, produce pre-leave documentation of the decision.
[ ] Resume non-health benefits at the prior level with no new waiting period; do not reduce accrued seniority.
[ ] If the employee does not return, evaluate whether the employer may recover its share of health premiums — not available where the failure to return results from continuation of the condition or circumstances beyond the employee's control. § 825.213.
[ ] On exhaustion, do not auto-terminate. Open the ADA interactive process in writing and evaluate additional leave, reduced schedule, reassignment, or other accommodation.
[ ] Evaluate remaining state PFML, state/local sick leave, workers' compensation, and CBA entitlements.

Why it matters, and the traps. The auto-termination-at-twelve-weeks policy is among the most reliably litigated practices in employment law and has been a sustained EEOC enforcement target. FMLA exhaustion is the start of the disability analysis, not the end of the employment relationship. See The Interactive Process: How Reasonable Accommodation Actually Works Under the ADA, Handling an Accommodation Request Under the ADA: A Practical Checklist, and Disability Discrimination and Accommodation: A Comprehensive Guide to the ADA and Rehabilitation Act.

On "equivalent position": a lateral move at the same pay to a role with less responsibility is not equivalent, and this is where restoration disputes usually live.

Phase 13 — The state-law overlay

For every request, run the same twelve questions against each jurisdiction where the employee works:

[ ] Is the employer covered? (Many state PFML programs have no size threshold.)
[ ] Is the employee eligible? (Often an earnings or contribution test, not 12 months/1,250 hours.)
[ ] What family relationships are covered? (Frequently broader — domestic partners, siblings, grandparents, in-laws.)
[ ] What qualifying reasons? (Often includes safe leave for domestic violence, sexual assault, or stalking.)
[ ] How long is the entitlement, and is family leave separate from medical leave?
[ ] What is the wage replacement rate and cap?
[ ] Who funds it, and what are the contribution obligations?
[ ] Is there a waiting period, and may PTO cover it?
[ ] Does it run concurrently with FMLA, or can it be taken sequentially?
[ ] Who adjudicates the medical evidence — the employer or a state agency?
[ ] Is job protection provided, and does it extend past twelve weeks?
[ ] Is a private or voluntary plan permitted?

Why it matters, and the traps. The employee is not going to identify the right statute. Compliance with one law is not a defense to violating another, and the employee gets the benefit of whichever is more generous. Build a single intake that evaluates FMLA, state PFML, state and local sick leave, ADA, workers' compensation, and any CBA provision at once. Write the handbook policy as a framework with a jurisdiction-specific appendix, so a legislative amendment does not require reissuing the handbook.

Phase 14 — Records and audit

[ ] Retain FMLA records for three years: payroll and identifying data, hours worked, leave dates and hours, all employee and employer notices, benefit and leave policies, premium payment records, and any designation disputes. 29 C.F.R. § 825.500.
[ ] Keep medical records separate and confidential.
[ ] Confirm the FMLA poster (WHD Publication 1420) is displayed at every worksite and the general notice appears in the handbook.
[ ] Pull ten closed leave files a year and audit them against this checklist.
[ ] Retrain supervisors annually on the one rule: route, do not evaluate.

Why it matters. The annual file audit is the only way to learn whether the process you designed is the process being run. It routinely surfaces the same three findings: missing designation notices, protected absences counted in the attendance system, and certifications never recertified.

The five habits that prevent most FMLA liability

Supervisors route the same day; they never evaluate and never call a provider.
WH-381 and WH-382 go out on the five-business-day clocks, every time.
Essential job functions and GINA safe-harbor language accompany every certification request.
Protected absences are excluded from attendance, bonus, and perfect-attendance systems.
Every open intermittent file is recertified at six months.
