Often, yes. If you and your employer meet the FMLA's eligibility rules, you can take up to 12 workweeks of unpaid, job-protected leave in a 12-month period for substance use treatment, as long as a health care provider gives the treatment or refers you to it. Missing work because of the substance use itself is not protected. eCFR: 29 CFR 825.119; DOL Fact Sheet #28.

This is general information, not legal advice. Your employer's policies and your own situation matter.

Who qualifies for FMLA leave?

Covered employers:

• Private employers with 50 or more employees in 20 or more workweeks in the current or previous calendar year
• Public agencies and public or private elementary and secondary schools, regardless of size

Eligible employees must:

• Have worked for the employer for at least 12 months (the months do not have to be consecutive)
• Have at least 1,250 hours of service in the 12 months before the leave starts
• Work at a location where the employer has at least 50 employees within 75 miles

DOL Fact Sheet #28; eCFR: 29 CFR 825.110.

Florida's own family medical leave statute covers state career-service employees, not private employers. Florida Statutes 110.221.

Does rehab count as a serious health condition?

It can. Substance use can be a "serious health condition" when the usual inpatient-care or continuing-treatment requirements are met. eCFR: 29 CFR 825.119.

• Inpatient care means an overnight stay in a hospital or residential medical care facility. eCFR: 29 CFR 825.114. The Department of Labor's mental health fact sheet names "a treatment center for addiction" as an example. DOL Fact Sheet #28O.
• Continuing treatment can cover care without an overnight stay, such as repeated visits with a provider or a course of prescription medication. eCFR: 29 CFR 825.113.

Leave is protected for treatment by a health care provider, or by a program a health care provider referred you to. Days missed because of drinking or drug use, rather than treatment, do not qualify.

Can you be fired for going to rehab?

Your employer cannot punish you for using FMLA leave for treatment, but the protection has limits. eCFR: 29 CFR 825.119.

The same rule lets an employer terminate an employee under an established substance use policy that was communicated to all employees and is applied in a non-discriminatory way, whether or not the employee is on FMLA leave. More broadly, FMLA leave gives you no greater right to your job than if you had kept working. eCFR: 29 CFR 825.216.

Two practical steps help:

1. Read your handbook's drug and alcohol policy before you make the request.
2. Ask early. Treatment does not erase discipline already issued. In one EEOC example, an employee asked for treatment leave after a final warning about lateness. The employer had to grant the leave, absent undue hardship, but did not have to withdraw the warning. EEOC: Applying performance and conduct standards.

Discouraging you from using leave you are entitled to can count as interference. eCFR: 29 CFR 825.220.

Can you use FMLA for outpatient, PHP, or IOP?

Yes, when it is medically necessary. FMLA leave can be taken in separate blocks of time or as a reduced schedule, such as working part-time during treatment. eCFR: 29 CFR 825.202. That can matter for a partial hospitalization program or an intensive outpatient program, which run on a set treatment schedule rather than an overnight stay.

For planned treatment, you must make a reasonable effort to schedule it so it does not unduly disrupt your employer's operations. eCFR: 29 CFR 825.203. Your employer may temporarily transfer you to a position with equivalent pay and benefits that better fits the schedule. eCFR: 29 CFR 825.204.

Our guide to IOP vs. PHP explains how the two differ.

Can you take FMLA leave to care for a family member in rehab?

Yes, for some family members. The regulations allow FMLA leave to care for a covered family member who is receiving substance use treatment, and they bar employers from acting against you for providing that care. eCFR: 29 CFR 825.119.

Covered family members are:

• A spouse, including a same-sex or common-law spouse whose marriage is recognized under the rule. Unmarried partners are not included.
• A parent, not including parents-in-law.
• A child under 18, or an adult child who is "incapable of self-care because of a mental or physical disability."

eCFR: 29 CFR 825.122. The adult-child rule is narrow: the child must need help or supervision with three or more daily activities, such as dressing, cooking, or paying bills.

"Care" includes physical help, such as transportation, and "psychological comfort and reassurance" for a family member receiving inpatient or home care. eCFR: 29 CFR 825.124.

What do you have to tell your employer?

• Timing. Give 30 days' notice for planned treatment. If that isn't possible, give notice as soon as practicable. eCFR: 29 CFR 825.302. If you can't call in yourself, a spouse or other responsible adult can give notice for you. eCFR: 29 CFR 825.303.
• Content. You don't have to say "FMLA" the first time, and "you do not have to tell your employer your diagnosis." You must show the leave may be for a qualifying condition, such as care from a health care provider. DOL Employee's Guide to the FMLA.
• Certification. Your employer may require a form completed by your provider, usually due within 15 calendar days. eCFR: 29 CFR 825.305. The medical facts on it "may include" a diagnosis. eCFR: 29 CFR 825.306. The Department of Labor's optional form is WH-380-E for your own condition, or WH-380-F for a family member's. DOL: FMLA forms.

How private is rehab from your employer?

Several rules limit who sees what:

• Your direct supervisor can never contact your health care provider. HR or another permitted contact may reach out only to clarify or authenticate the form, and you cannot be required to sign a release letting your employer talk to your provider. eCFR: 29 CFR 825.307; eCFR: 29 CFR 825.306.
• FMLA medical records must be kept confidential, in files separate from your regular personnel file. eCFR: 29 CFR 825.500. Supervisors may be told that you need time away or need accommodations. DOL Fact Sheet #28O.
• Many treatment records have extra federal protection. Under 42 CFR Part 2, records from federally assisted substance use disorder programs can be used or disclosed only as that rule allows, and many disclosures require your written consent. eCFR: 42 CFR 2.13.

Before you sign any release for employer paperwork, ask exactly what it allows the program to share.

What if you don't qualify for FMLA?

The Americans with Disabilities Act may still help. It applies to employers with 15 or more employees. EEOC: ADA Titles I and V.

• People in recovery and in treatment. The ADA does not protect current illegal drug use. It can protect people who are in or have completed supervised rehabilitation and are no longer using illegally. EEOC: ADA Titles I and V. People taking prescribed medication for opioid use disorder generally cannot be fired for that legal use. ADA.gov: The ADA and opioid use disorder.
• Alcohol use disorder. The ADA may protect a qualified person whose alcohol use disorder meets its definition of disability. Employers can still hold everyone to the same performance and conduct standards. EEOC: Applying performance and conduct standards.
• Leave as an accommodation. Employers must consider unpaid leave as a reasonable accommodation, even if you are not eligible for FMLA or have used it up, unless it would cause undue hardship. EEOC: Employer-provided leave and the ADA. A schedule change to attend treatment is another possible accommodation. EEOC: Opioid use and the ADA.

Florida's Civil Rights Act separately prohibits handicap discrimination by employers with 15 or more employees. Florida Statutes 760.10; Florida Statutes 760.02.

Is FMLA leave paid?

No, but you may be able to use paid leave during it. You can choose, or your employer can require, to run accrued sick or vacation time at the same time as FMLA leave, under the employer's normal leave policy. eCFR: 29 CFR 825.207. Your employer must also keep your group health coverage on the same terms. DOL Fact Sheet #28.

If you have short-term disability coverage, ask HR or read the plan to learn whether it covers substance use or mental health treatment and what waiting periods apply.

Who should you ask?

• HR or your leave administrator about eligibility, notice rules, and the substance use policy.
• The U.S. Department of Labor's Wage and Hour Division at 1-866-487-9243, for FMLA questions or complaints. DOL Fact Sheet #28.
• The Florida Commission on Human Relations about discrimination under Florida law.
• An employment attorney, if you have been disciplined, denied leave, or fired.

Frequently asked questions

Do I have to tell my employer I'm going to rehab?

Not when you first give notice, but you must give enough information to show the leave may qualify. A certification form, if required, may include a diagnosis.

Does FMLA cover detox?

It can, when a health care provider supervises it and the other FMLA requirements are met. An overnight stay in a residential medical facility counts as inpatient care.

Can my employer deny FMLA leave for rehab?

Yes, if you or the employer don't qualify, or if you don't give notice or complete a required certification. It can't deny leave that qualifies, though a uniformly applied substance use policy can still apply.

Planning treatment around work with Ambrosia

Ambrosia's admissions team answers the phone 24 hours a day and can talk through timing and the level of care that may fit. For PHP or IOP, ask for the current days, hours, and attendance requirements before you arrange work. If your employer wants certification, ask how the program handles employer forms and what consent you would sign.

Insurance verification is free and does not commit you to treatment. For the basics of the law, see our FMLA and treatment overview. Planning a residential stay? Here is what to pack for residential treatment.
