If your business employs 50 or more people, the Family and Medical Leave Act requires you to give eligible workers up to 12 weeks of unpaid, job-protected leave each year (26 weeks in military caregiver cases), continue their group health coverage during the absence, provide four specific written notices, restore them to the same or an equivalent job, and keep FMLA records for three years. The FMLA requirements for employers reach well beyond simply approving time off, and the procedural steps carry as much legal weight as the leave itself. Miss a notice deadline or mishandle a premium payment, and you can lose the ability to enforce the rules against the employee or face doubled damages in court.
Are You a Covered Employer
A private-sector business is covered when it employs 50 or more people during at least 20 calendar workweeks in the current or preceding calendar year.1eCFR. 29 CFR 825.104 – Covered Employer Part-time workers count. So do employees on any type of leave, as long as you reasonably expect them to return. Anyone maintained on the payroll counts for every working day of the week, regardless of hours actually worked.2eCFR. 29 CFR 825.105 – Counting Employees for Determining Coverage
Public agencies at every level of government and public elementary and secondary schools are covered regardless of headcount.3eCFR. 29 CFR 825.108 – Public Agency Coverage
Joint Employment and Staffing Agencies
When two businesses share control over the same worker — typical in temp arrangements — both are FMLA employers. The primary employer is usually whoever hires, fires, assigns work, and provides benefits, which in a staffing agency setup is normally the agency. The primary employer handles all required FMLA notices, grants leave, maintains health coverage, and restores the worker to their job. The secondary employer cannot fire or punish a jointly-employed worker for taking FMLA leave. Both count jointly-employed workers toward their own 50-employee threshold.4U.S. Department of Labor. Fact Sheet 28N – Joint Employment and Primary and Secondary Employer Responsibilities Under the Family and Medical Leave Act
If You Acquired Another Business
Buying or taking over another company can make you a “successor in interest” that inherits its FMLA obligations. The Department of Labor weighs continuity of operations, workforce, jobs and working conditions, supervisors, and equipment.5U.S. Department of Labor. Family and Medical Leave Act Advisor – Successor in Interest When most of those factors point to continuity, the new owner picks up where the predecessor left off.
Which of Your Employees Are Eligible
Not everyone who works for a covered employer qualifies. All three conditions must be met:
- The employee has worked for you for at least 12 months, and those months do not have to be consecutive.
- The employee has logged at least 1,250 hours of actual work during the 12 months immediately before the leave starts.
- At least 50 of your employees work within 75 miles of the employee’s worksite.6eCFR. 29 CFR 825.110 – Eligible Employee
The 75-mile rule trips up multi-location employers. A worker at a small satellite office with 15 coworkers can still be eligible if the company has 50 or more employees across all worksites within a 75-mile radius. Conversely, someone at a remote location with no other company sites nearby may not qualify even if you employ thousands elsewhere.
The Reasons You Must Grant Leave
An eligible employee can take up to 12 workweeks of unpaid leave in a 12-month period for:
- The birth of a child and bonding within the first year.
- Placement of a child for adoption or foster care, and bonding within the first year.
- Care for a spouse, child, or parent with a serious health condition.
- The employee’s own serious health condition that prevents them from performing their job.
- A qualifying exigency arising from a spouse’s, child’s, or parent’s covered active duty or call to active duty.
A separate 26-week entitlement in a single 12-month period applies to an employee who is the spouse, child, parent, or next of kin of a covered servicemember with a serious injury or illness. In that same window, the employee’s combined FMLA leave for any reason cannot exceed 26 weeks.7Office of the Law Revision Counsel. 29 USC 2612 – Leave Requirement
The Four Notices You Owe
FMLA imposes four distinct notice obligations. Missing any of them can undermine your ability to enforce deadlines or count leave against the employee’s entitlement.
General Poster
Every covered employer must display a poster explaining FMLA rights where employees and applicants can see it, even if you currently have no eligible employees.8eCFR. 29 CFR 825.300 – Employer Notice Requirements Willful failure to post carries a civil penalty of up to $216 per offense.9U.S. Department of Labor. Civil Money Penalty Inflation Adjustments
Eligibility Notice
When an employee requests leave or you learn an absence may qualify, you have five business days to tell the employee whether they are eligible. If not, the notice must state at least one reason why.8eCFR. 29 CFR 825.300 – Employer Notice Requirements
Rights and Responsibilities Notice
Alongside the eligibility notice, provide a written document explaining the employee’s obligations and the consequences of not meeting them: medical certification requirements, how health insurance premiums will be handled during leave, the right to substitute accrued paid leave, and what happens if the employee does not return to work.
Designation Notice
Once you have enough information to decide whether the leave qualifies — usually after receiving medical certification — you have five business days to tell the employee whether the leave counts as FMLA-protected and how much will be charged against their annual entitlement.
Medical Certification
You can require a certification from a health care provider supporting the need for leave for a serious health condition. Once you request it, the employee gets at least 15 calendar days to submit. If good-faith efforts cannot meet that timing, extend it.10U.S. Department of Labor. Family and Medical Leave Act Advisor – Medical Certification
If the certification is questionable, you can require a second opinion from a provider you choose, at your expense. Conflicting opinions are resolved by a third opinion from a mutually agreed-upon provider, again at your cost. The employee’s direct supervisor cannot contact the health care provider; that communication runs through HR, a benefits administrator, or another health care provider.
An incomplete or insufficient certification is not grounds for automatic denial. Give the employee a written explanation of what is missing and at least seven calendar days to fix it.
Intermittent and Reduced Schedule Leave
Leave does not have to come in one block. A chronic condition may need a few hours weekly for treatment. A family caregiver may need occasional days as a relative’s health shifts. Intermittent leave is the hardest to administer because it disrupts scheduling without predictability.
Track it using an increment no larger than the shortest one you use for any other type of leave, and no larger than one hour. If your payroll tracks sick leave in 15-minute increments, FMLA leave uses 15-minute increments too. You cannot dock more time from the employee’s entitlement than they actually missed.11eCFR. 29 CFR 825.205 – Increments of FMLA Leave for Intermittent or Reduced Schedule Leave
When the need is foreseeable planned treatment, you can temporarily move the employee to an alternative position that better accommodates recurring absences, as long as the pay and benefits are equivalent.12eCFR. 29 CFR 825.204 – Transfer of an Employee to an Alternative Position For production environments where partial-day absences create staffing headaches, this is a useful tool.
Keeping Health Coverage in Force
Group health coverage continues during FMLA leave on the same terms as if the employee were still working: same plan, same employer contribution, same coverage level.13eCFR. 29 CFR 825.209 – Maintenance of Employee Benefits For unpaid leave, you still collect the employee’s premium share. You can require payment on the normal payroll schedule or another arrangement, but you cannot add an administrative surcharge to the employee’s usual share.14GovInfo. 29 CFR 825.209 – Maintenance of Employee Benefits
Dropping Coverage for Non-Payment
If a premium payment is more than 30 days late, you may drop coverage, but only after mailing a written notice at least 15 days before the termination date, giving the employee a final chance to pay.15eCFR. 29 CFR 825.212 – Employee Failure to Pay Health Plan Premium Payments Skip that 15-day letter and you have likely created an interference claim.
Recovering Premiums When the Employee Does Not Return
If you paid the employer’s share of premiums during unpaid leave and the employee never returns, you can generally recover those costs. The right disappears if the failure to return is caused by a continuing serious health condition (the employee’s own or a family member’s) or circumstances beyond the employee’s control. You can ask for medical certification supporting a health-related reason; if the employee does not provide it within 30 days, recovery is available.16U.S. Department of Labor. Family and Medical Leave Act Advisor – Recovery of Health Insurance Premiums An employee who returns for at least 30 calendar days has “returned to work,” and recovery is off the table.
Restoring the Employee’s Job
When the employee comes back, you must place them in the same position they held before the leave or in a genuinely equivalent one. Equivalent means virtually identical in pay, benefits, and working conditions, with substantially similar duties, responsibilities, skill, and authority.17eCFR. 29 CFR 825.215 – Equivalent Position The details matter: same shift or an equivalent schedule, same worksite or one that does not significantly lengthen the commute, and any unconditional pay raises that occurred during the leave applied to the returning employee’s pay. Restoration applies even if you filled the position or restructured the role during the absence.18eCFR. 29 CFR 825.214 – Employee Right to Reinstatement
The Key Employee Exception
A narrow exception lets you deny reinstatement to a “key employee” — a salaried, FMLA-eligible worker among the highest-paid 10 percent of your employees within 75 miles of the worksite.19eCFR. 29 CFR 825.217 – Key Employee, General Rule You can invoke it only if restoring the employee would cause substantial and grievous economic injury to your operations. That is a high bar. You must notify the employee of the key employee status when you designate them and again when you actually decide to deny restoration, giving them a chance to return to work immediately.
Choosing Your 12-Month Leave Year
You have to pick a consistent method for measuring the 12-month period. The regulations offer four options:
- The calendar year, January 1 through December 31.
- A fixed 12-month period such as your fiscal year or the employee’s hire anniversary.
- A forward-rolling period that begins on the first day the employee takes FMLA leave.
- A backward-rolling period, in which each request triggers a look-back over the preceding 12 months to subtract leave already used.
Apply the method uniformly to all employees.20eCFR. 29 CFR 825.200 – Amount of Leave Backward-rolling is popular because it prevents an employee from stacking leave at the end of one year and the start of the next.
What Non-Compliance Costs
Federal law makes it illegal to interfere with, restrain, or deny the exercise of FMLA rights, and equally illegal to fire or punish an employee for taking leave, filing a complaint, or participating in an investigation.21Office of the Law Revision Counsel. 29 USC 2615 – Prohibited Acts Interference claims do not require proof of bad intent. If your action had the effect of discouraging or preventing FMLA use, that can be enough. Counting FMLA absences under a no-fault attendance policy, pressuring employees to work during leave, or skipping the required notices are common examples.
An employer who violates the interference or retaliation rules is liable for the employee’s lost wages, salary, and benefits, plus interest. The statute adds liquidated damages equal to the total of lost compensation and interest, effectively doubling the payout. A court can reduce or eliminate liquidated damages only if you prove the violation was made in good faith with reasonable grounds to believe the action was lawful.22Office of the Law Revision Counsel. 29 USC 2617 – Enforcement
Where no wages were lost, the employer can still be liable for the employee’s actual out-of-pocket costs such as outside caregiving, capped at 12 weeks of wages. Courts must award reasonable attorney’s fees and expert witness costs to a prevailing employee, which often exceed the underlying damages in smaller cases.22Office of the Law Revision Counsel. 29 USC 2617 – Enforcement The $216 posting fine is minor compared to the litigation exposure from inadequate notices.
Records You Must Keep
Retain FMLA-related records for at least three years. That includes basic payroll and identifying data, dates of FMLA leave taken, and copies of every written notice exchanged with the employee — what they submitted and what you provided.23eCFR. 29 CFR 825.500 – Recordkeeping Requirements No specific format is required; electronic records work as long as you can produce them for a Department of Labor investigation. These records are not filed with any agency. They exist to prove compliance if the DOL asks or an employee files a complaint. Employers who granted leave informally and kept no paper trail are the ones who cannot show whether absences were counted correctly or whether notices went out on time.
