FMLA Administration: A Practical Guide for Small Business HR

The FMLA Mistakes That Cost Employers the Most

The Family and Medical Leave Act has been law since 1993. It should be well-understood by now — and yet FMLA violations remain among the most common employment law claims, and many of the violations follow the same predictable patterns.

For fractional HR consultants, FMLA administration is one of the areas where hands-on expertise creates the most tangible protection for clients. The employer's duty to correctly identify FMLA-qualifying situations — even when the employee doesn't know they have FMLA rights — is one of the most counterintuitive requirements in employment law, and it trips up even experienced managers.

Who Is Covered

FMLA applies to employers with 50 or more employees within 75 miles of a worksite for at least 20 workweeks in the current or preceding calendar year. This threshold catches more employers than they sometimes realize — if you have 40 employees at one location and 15 more at a satellite office 50 miles away, that's 55 employees within 75 miles.

Eligible employees must have worked for the employer for at least 12 months and at least 1,250 hours in the 12 months preceding leave. The 12 months need not be continuous — prior service counts even after a break, as long as it doesn't exceed 7 years (with exceptions).

Qualifying Reasons for FMLA Leave

FMLA covers six categories:

1. ✦The birth of a child and to care for the newborn within the first year
2. ✦The placement of a child for adoption or foster care within the first year
3. ✦To care for a spouse, child, or parent with a serious health condition
4. ✦The employee's own serious health condition that renders them unable to perform essential job functions
5. ✦Qualifying exigency related to a family member's military service
6. ✦To care for a covered servicemember with a serious injury or illness (military caregiver leave — up to 26 weeks)

The most litigated category is "serious health condition." The definition covers conditions requiring inpatient care or continuing treatment by a healthcare provider — including chronic conditions (like diabetes, asthma, or migraines) that require periodic treatment and may cause episodic incapacity.

The Duty to Designate: Where Most Employers Go Wrong

Here's the piece that surprises most managers: employers are required to identify FMLA-qualifying situations and designate leave as FMLA even when the employee doesn't ask for FMLA.

If an employee calls in sick with a medical condition that might be FMLA-qualifying, the employer has a duty to inquire further and potentially designate that absence as FMLA. Waiting for the employee to invoke FMLA, or failing to designate qualifying absences, is itself an FMLA violation.

The practical implication: when an employee reports an absence for medical reasons, managers should notify HR. HR reviews whether the situation is potentially FMLA-qualifying. If it might be, you send the notice and certification paperwork. The employee's knowledge of their FMLA rights doesn't trigger the process — the circumstances do.

The Required Notices

FMLA requires four specific notices with defined deadlines:

General Notice. Must be posted in a conspicuous location and included in employee handbooks. Remote employees must receive it another way.

Eligibility Notice. When an employee requests FMLA leave or you become aware of a potentially qualifying situation, you must notify the employee of their eligibility within 5 business days.

Rights and Responsibilities Notice. Provided at the same time as the eligibility notice. Explains the employee's obligations during leave — including medical certification requirements.

Designation Notice. After receiving sufficient information to make a determination, you must notify the employee of the leave designation (approved or denied) within 5 business days.

Missing these notices is not a technicality. Courts have found that failure to provide required notices prevented employers from enforcing FMLA requirements — including maximum leave limits — because the employee wasn't properly informed of their obligations.

Managing Intermittent Leave

Intermittent FMLA is the most administratively challenging scenario. An employee with a chronic condition may be approved for intermittent leave — meaning they can take leave in individual days or partial days for FMLA-qualifying episodes without pre-approval for each absence.

Tips for managing it correctly:

Require medical certification that specifies the expected frequency and duration. "As needed" is not sufficient. The certification should indicate the expected number of episodes per month and the duration of each.

Track intermittent absences separately. Absences taken under approved intermittent FMLA cannot be counted in an attendance program, even if your policy would otherwise result in discipline. Mixing FMLA and non-FMLA absences in a points-based attendance system is a common source of retaliation claims.

Recertify appropriately. You can request recertification every 30 days in connection with an absence, every 6 months regardless of absences, or sooner if circumstances change materially.

Transfer to an equivalent position. When intermittent leave is foreseeable, you can transfer the employee to an alternative equivalent position with equivalent pay and benefits that better accommodates the leave schedule — as long as it's truly equivalent.

When Leave Ends

Reinstatement to the same or equivalent position is the default FMLA requirement. Exceptions exist for key employees (highest-compensated 10% within 75-mile radius) whose reinstatement would cause substantial and grievous economic injury — but the notice requirements for invoking this exception are strict.

The most common reinstatement mistake: requiring a fitness-for-duty certification only from the employee's treating physician (appropriate) but then adding requirements beyond what the regulations allow, or refusing to accept the certification for reasons not grounded in the law.

The second most common mistake: terminating an employee while they're on FMLA leave for a stated business reason. Legitimate RIFs can include FMLA employees — but the timing creates strong inference of FMLA retaliation that requires careful documentation to defend.

FMLA administration is procedurally demanding. The employers who get it right tend to have a defined process for identifying qualifying situations, providing notices on time, and tracking leave accurately — rather than handling each situation ad hoc and hoping for the best. The FMLA Administration Kit generates the required notices, timelines, and tracking documentation for a specific employee situation. For multi-state clients juggling FMLA alongside state PFML programs, the Leave Law Configurator maps the interaction of overlapping requirements.
