FMLA and Mental Health: Who Qualifies and How Leave Works

Yes, under the Family and Medical Leave Act (FMLA) a mental health condition counts as a "serious health condition" on the same terms as a physical one, when it requires inpatient care or continuing treatment by a health care provider^[1]. That is the core of how FMLA and mental health interact, and it is the U.S. Department of Labor's own reading of the law in its May 2022 fact sheet on the subject^[1].

The question affects a large share of the workforce. In the 2025 National Survey on Drug Use and Health, 20.6% of U.S. adults (54.6 million) had any mental illness in the past year^[6]. The FMLA does not cover every one of those people, because both the worker and the condition have to meet specific tests.

Eligible employees can use FMLA leave for their own condition, or to care for a spouse, child or parent with a serious health condition^[1]. Covered employers must keep group health benefits running during leave and restore the employee to the same or a virtually identical job afterward^[1].

The FMLA does not keep a list of approved diagnoses. A condition qualifies by how it is treated and how much it disrupts daily functioning, not by its name. The Labor Department describes three ways a mental health condition can meet that definition^[1]:

• Inpatient care: an overnight stay in a hospital or other medical care facility, such as a treatment center for addiction or an eating disorder.
• Incapacity plus ongoing treatment: being unable to function for more than three consecutive days, combined with multiple visits to a provider or one visit followed by continued care such as prescription medication or behavioral therapy.
• Chronic conditions: conditions such as anxiety, depression or dissociative disorders that cause occasional periods of incapacity and need treatment at least twice a year.

The providers whose care counts include psychiatrists, clinical psychologists and clinical social workers^[1]. An overnight psychiatric stay, described in the site's guide to inpatient mental health treatment, fits the first route^[1].

What about stress or burnout?

The Labor Department's mental health guidance does not name work stress or burnout as qualifying conditions. A stress-related absence is judged by the same tests as any other: whether the person is incapacitated and receiving the required level of treatment^[1]. The label on the absence matters less than what the health care provider certifies.

Two tests apply: the employer has to be covered, and the employee has to be eligible. Private employers are covered if they had 50 or more employees in 20 or more workweeks in the current or prior calendar year^[1]. Public agencies and public and private elementary and secondary schools are covered regardless of size^[1].

An employee is eligible after working for a covered employer for at least 12 months, logging at least 1,250 hours in the 12 months before leave, and working at a location with at least 50 employees within 75 miles^[1]. Part-time workers, new hires and staff at small satellite offices can fall short of one of these thresholds.

In the Labor Department's 2018 FMLA surveys, the most recent national wave, 56% of employees were eligible based on their tenure, hours and worksite size^[2]. About 27% of employees surveyed incorrectly believed they met the eligibility requirements^[2]. Prevalence of mental illness among employed adults is covered on the population page.

Eligible employees can take up to 12 workweeks of leave in a 12-month period for their own serious health condition^[8]. Military caregiver leave is longer: up to 26 workweeks in a single 12-month period to care for a covered servicemember or certain veterans^[1].

The leave does not have to be taken all at once. When medically necessary, it can be used in separate blocks or as a reduced schedule^[8]. That intermittent option is what lets a worker keep a scheduled treatment appointment or miss an unplanned day when symptoms flare without losing protection^[1].

FMLA leave is unpaid. Employees can run employer-provided paid leave at the same time when the reason is covered by the employer's policy, and employers can require it^[8]. In March 2026, 81% of private-industry workers had access to paid sick leave and 49% had access to paid family and medical leave; among state and local government workers the figures were 93% and 57%^[4].

Thirteen states and the District of Columbia have laws creating paid family and medical leave programs, and three more states have voluntary insurance programs^[9]. Nothing in the FMLA prevents employees from also using protections under state laws^[3]. Insurance coverage for the treatment itself is a separate question, tracked in the site's mental health insurance coverage statistics.

An employer may require a certification from a health care provider. The employee generally has 15 calendar days after the request to return it, with more time allowed when the employee makes diligent, good-faith efforts^[3]. The Labor Department publishes optional form WH-380-E for an employee's own condition and WH-380-F for a family member's^[3].

The provider may, but is not required to, give a diagnosis^[3]. An employer may ask the certification to cover the condition's start date and expected duration, relevant medical facts, why the employee cannot perform essential job functions and, for intermittent leave, how often and how long absences are likely to be^[3].

Clinical psychologists and clinical social workers are among the professionals who can certify, alongside physicians, nurse practitioners and physician assistants^[3]. That matters for people whose main care comes from a therapist rather than a prescriber.

What employers can and cannot do with it

The employee's direct supervisor may never contact the employee's health care provider. HR, a leave administrator, a management official or another health care provider may contact the provider only to authenticate or clarify the form^[3]. If the employer doubts a complete certification, it can require a second opinion, and a third if the two conflict, at the employer's expense^[3].

Recertification can generally be requested no more often than every 30 days and only in connection with an absence, though every six months is allowed in all cases^[3]. Medical records must be kept confidential and in files separate from regular personnel records^[1]. Supervisors and managers may be informed that the employee needs to be away or needs work restrictions or accommodations^[1].

Employers are prohibited from interfering with, restraining or denying FMLA rights. The Labor Department's examples include refusing to authorize leave and threatening to disclose a family member's mental health condition to discourage someone from taking leave^[1].

Substance use has a specific rule: FMLA leave covers treatment by or on referral from a health care provider, but absence caused by the use of the substance itself does not qualify^[7]. An employer cannot act against an employee for taking FMLA leave for treatment, but an established, consistently applied and communicated substance use policy can still be enforced^[7]. Prevalence data sit on the substance use disorder page.

Before return, an employer may require a fitness-for-duty certification if it has a uniform policy for similar jobs and conditions and gave notice of the requirement^[3]. It cannot demand one for each intermittent absence, except up to once every 30 days when it reasonably believes the return poses a significant risk of harm^[3].

In the 2018 surveys, 87% of employees who took leave returned to the same employer and position^[2]. Among low-wage workers, 18% reported losing their job because of taking leave^[2]. A 2020 Cochrane review of 45 studies with 12,109 participants found that pairing a work-directed intervention with clinical care probably reduces sickness-absence days for depressed workers in the first year, but did not lead to fewer people being off work at one year or longer^[10].

Caring for a spouse, child or parent with a serious mental health condition is a qualifying reason. Care includes psychological comfort and reassurance for a family member receiving inpatient or home care^[1]. In one Labor Department example, a parent uses a day of FMLA leave to attend an after-care meeting at the inpatient facility where a teenage son completed drug rehabilitation^[1].

For an adult child, the rules tighten. A parent can take leave for a son or daughter 18 or older only if the child is incapable of self-care because of a disability and needs care for a serious health condition^[1]. The disability need not have started before age 18^[1].

The FMLA borrows the ADA definition here, and EEOC regulations say major depressive disorder, bipolar disorder, post-traumatic stress disorder, obsessive compulsive disorder and schizophrenia should easily be concluded to be substantially limiting^[1]. The site's explainer Is ADHD a Disability? walks through how that ADA test works. Data on unpaid caregivers are on the family caregivers page.

Military caregiver leave also covers mental health. It can apply when a veteran's PTSD, traumatic brain injury or depression appears well after the qualifying service event^[1].

The Labor Department's 2018 surveys of 4,470 employees are the most recent national data on FMLA use^[2]. They do not break results out by mental health condition, so the figures below describe all qualifying reasons.

Fifteen percent of employees took leave for a qualifying reason in the prior 12 months^[2]. Of those leave-takers, 51% did so for their own serious illness^[5]. The average leave lasted 28 business days, and 40% of leaves were 10 days or shorter^[5].

Not taking needed leave was common. Two-thirds of employees with unmet need said they could not afford unpaid leave, and 24% believed their health condition did not qualify^[5]. Among those whose unmet need was medical, 44% postponed treatment and 39% went without it^[5].

Workers who are not FMLA-eligible, or who have used their 12 weeks^[8], may still have rights under the Americans with Disabilities Act. The EEOC says unpaid leave can be a reasonable accommodation when an employee cannot perform essential job functions, has no paid leave left, and the leave would help them get back to performing those functions^[11].

The ADA also covers accommodations short of leave, such as altered schedules built around therapy appointments, quieter workspaces and permission to work from home^[11]. An employer can ask for documentation, but a provider's note describing the condition generally, such as "an anxiety disorder," may be enough without naming the specific diagnosis^[11].

Discrimination charges with the EEOC must generally be filed within 180 days, or 300 days where a state or local law also applies^[11]. FMLA complaints go to the Labor Department's Wage and Hour Division or to court^[1]. Broader employer practices are covered in the site's guide to mental health in the workplace.
