This is one of the procedures covered in Michigan labor laws. Michigan has no family and medical leave act of its own, so a leave request from a Michigan employer is governed entirely by federal law and administered by the U.S. Department of Labor’s Wage and Hour Division. What follows is the application sequence in order: confirming eligibility, giving notice, handling the certification form, and reading the designation notice that comes back.
Who is eligible for FMLA leave in Michigan
Two separate tests apply. The employer has to be covered, and the employee has to be eligible. Failing either one ends the analysis.
A private-sector Michigan employer is covered if it employed 50 or more employees in 20 or more workweeks in the current or preceding calendar year, according to Fact Sheet #28 from the Wage and Hour Division. Public agencies and local educational agencies are covered regardless of headcount, which sweeps in Michigan school districts, city and county governments, and state agencies even when a particular office is small. The definitions sit in 29 U.S.C. § 2611.
An individual employee is eligible only after clearing three thresholds set by 29 C.F.R. § 825.110: at least 12 months of employment with that employer, at least 1,250 hours of service during the 12 months immediately before the leave begins, and a worksite where the employer has 50 or more employees within 75 miles. The 12 months do not have to be consecutive. The 1,250 hours are actual hours worked, not hours paid, which matters for salaried employees who take vacation.
The 75-mile radius disqualifies more Michigan workers than people expect. A manufacturer headquartered in Grand Rapids with 400 employees still owes no FMLA leave to a technician at a 12-person satellite shop in the Upper Peninsula if no other company location falls within 75 miles of that shop.
Notice: what the employer has to be told, and when
The timing of notice depends on whether the need for leave is foreseeable.
When the need is foreseeable, a scheduled surgery, an expected birth, a planned adoption placement, the employee gives at least 30 days advance notice under 29 C.F.R. § 825.302. When 30 days is not practicable because the need was not known that far ahead, notice is given as soon as practicable, which the regulation generally treats as the same or next business day after the need becomes known.
When the need is unforeseeable, 29 C.F.R. § 825.303 requires notice as soon as practicable under the facts, and an employee must follow the employer’s usual call-in procedures absent unusual circumstances. Failing to follow those procedures can delay or defeat the leave even when the underlying reason clearly qualifies.
The content of the notice matters less than people expect. An employee does not have to say the word “FMLA” or cite the statute. Enough information to make the employer aware the absence may be FMLA-qualifying is the standard described in Fact Sheet #28. “I’m having gallbladder surgery on the 14th and my doctor says two weeks out of work” satisfies it. “I need some time off” does not.
The application sequence
Most Michigan employers route requests through HR or a third-party leave administrator, but the underlying sequence is fixed by regulation regardless of who handles the paperwork.
Give notice of the reason and expected timing
Tell the employer the reason for the absence, when it starts, and roughly how long it runs. Put it in writing where possible, and follow the employer’s call-in rules. Verbal notice is legally sufficient, but a dated email creates a record of when notice was given.
Watch for the Eligibility and Rights and Responsibilities Notice
Once the employer has enough information to know the leave may qualify, 29 C.F.R. § 825.300 requires it to issue an eligibility notice within five business days, absent extenuating circumstances. Most employers use form WH-381, which states whether the employee is eligible or gives at least one reason why not.
Return the certification
If the employer requests medical certification, the employee obtains it from the health care provider and returns it within the time the employer allowed. The five certification forms published by the Wage and Hour Division are optional; an employer may use its own version requesting the same basic information.
Read the Designation Notice
Form WH-382 tells the employee whether the leave is designated as FMLA leave and how much time is counted against the 12-workweek entitlement. Section 825.300 also requires the employer to use this notice to identify a certification that is incomplete or insufficient.
Sort out pay
FMLA leave is unpaid. An employee may choose to use accrued paid leave concurrently, and an employer may require it, so long as the paid-leave policy covers the reason for the absence.
Medical certification and the 15-day window
An employer may require certification from a health care provider for leave based on a serious health condition. Under 29 C.F.R. § 825.305, the employer must allow at least 15 calendar days to return the completed form, and more time when the employee has made diligent good-faith efforts and the provider has not completed it in time. The 15 calendar days are a floor, not a ceiling; some Michigan employers write longer windows into their handbooks.
Certification of Health Care Provider for Employee's Serious Health Condition (WH-380-E)

The companion form for a family member’s condition is WH-380-F, and military family leave uses WH-384, WH-385, or WH-385-V. The Wage and Hour Division forms page lists all of them. Two points from that page come up in disputes often: the expired OMB date printed on the forms does not affect their validity, and an employer must accept a complete and sufficient certification in any format, including a letter on the provider’s letterhead.
When a returned certification is incomplete or unclear, the employer states in writing what is missing and gives the employee at least seven calendar days to cure it, under 29 C.F.R. § 825.305. An employer that doubts the certification may, at its own expense, require a second opinion from a provider it selects, and a binding third opinion if the first two conflict.
Michigan earned sick time alongside unpaid FMLA leave
The Michigan sick time law took effect February 21, 2025 and is enforced by the Department of Labor and Economic Opportunity. It reaches employers with one or more employees, a far wider group than the FMLA’s 50-employee threshold, and it provides paid time rather than extended job protection.
The usage caps differ by employer size. An employer with 10 or fewer employees is not required to allow more than 40 hours of paid earned sick time in a year, and an employer with 11 or more is not required to allow more than 72 hours, according to LEO’s earned sick time guidance. Those hours can be paid during an FMLA absence, since FMLA leave is unpaid and Fact Sheet #28 confirms that employer-provided paid leave may run at the same time.
The result for a Michigan worker with a serious health condition is two overlapping entitlements: earned sick time supplies pay for the first stretch of the absence, and the FMLA supplies job protection and health-insurance continuation for up to 12 workweeks under 29 U.S.C. § 2612. Military caregiver leave runs up to 26 workweeks in a single 12-month period.
If a Michigan employer denies or interferes with the request
29 U.S.C. § 2615 makes it unlawful for an employer to interfere with, restrain, or deny the exercise of FMLA rights, or to discharge or discriminate against someone for opposing a practice the statute forbids. Fact Sheet #28 lists examples Michigan employees run into regularly: assessing attendance points for FMLA absences, writing an employee up for missing covered work, or denying a promotion because leave was used.
This is one of the statutory limits on at-will employment. Because Michigan is an at-will employment state, most firings need no reason at all, and a discharge tied to an FMLA request is unlawful only because the federal statute carves it out. A discharge that follows a leave request is also one of the fact patterns covered in wrongful termination in Michigan.
Two enforcement routes exist. A complaint can be filed with the Wage and Hour Division, which administers the FMLA and operates a toll-free helpline at 1-866-487-9243, or an employee can bring a private lawsuit. Under 29 U.S.C. § 2617, an FMLA action must be brought within 2 years after the date of the last event constituting the violation, extended to 3 years for a willful violation.
No Michigan state agency enforces the FMLA. Michigan’s own Wage and Hour Division handles earned sick time claims, which carry a filing window of 3 years from the alleged violation, but a denied FMLA request goes to the federal agency or to court.
Frequently asked questions
Does a Michigan employer with fewer than 50 employees have to grant FMLA leave?
No. The 50-employee coverage threshold in 29 U.S.C. § 2611 applies to private-sector employers in Michigan the same way it applies everywhere else, and Michigan has no state statute filling the gap for smaller employers. Public agencies and local educational agencies are covered regardless of size. An employee of a small private employer may still have earned sick time under the state Earned Sick Time Act, and may have rights under the Americans with Disabilities Act if the condition qualifies as a disability.
How much notice does an employee owe for an unexpected hospitalization?
Notice as soon as practicable under the facts of the situation, per 29 C.F.R. § 825.303. For a genuine emergency, that often means notice from a family member or a call the following day rather than before the absence. The regulation also expects compliance with the employer’s usual call-in procedures unless unusual circumstances prevent it.
Can an employer require the use of paid vacation during FMLA leave?
Yes, when the employer’s paid leave policy covers the reason for the absence. Fact Sheet #28 states that employees may use employer-provided paid leave at the same time as FMLA leave, and that an employer may also require it. The entitlement itself remains 12 workweeks regardless of whether any of it is paid.
What happens if the certification form is returned late?
An employer that gave the required 15 calendar days and provided written notice of the consequences may deny FMLA protection for the absence until a complete certification arrives. Section 825.305 also requires additional time where the employee made diligent good-faith efforts and the health care provider did not complete the form on schedule. Documentation of when the form was requested from the provider is what typically decides these disputes.
Is FMLA leave in Michigan job-protected the whole time?
An eligible employee is entitled to return to the same or an equivalent job with the same pay, benefits, and other terms of employment, and group health coverage continues during the leave on the same terms as if the employee had kept working. Narrow exceptions exist, including for certain highly compensated key employees and for positions eliminated for reasons unrelated to the leave.
