Often, yes. The Family and Medical Leave Act (FMLA) gives eligible employees up to 12 weeks of unpaid, job-protected leave in a 12-month period for their own serious health condition, and substance use treatment can qualify.12 The ADA may add protection. The catch is eligibility, which depends on the employer’s size and how long your loved one has worked there.
How much time off they need depends on the level of care, so start with an assessment and then talk to HR.
Does FMLA cover rehab?
Yes. Labor Department rules say a substance use disorder may be a serious health condition, but leave counts only for treatment by a health care provider, or by a provider they were referred to by one.2 A day off after a binge is not FMLA leave. Detox, residential care and outpatient visits can be.2
Leave can also be taken in blocks as short as an hour, or as a reduced schedule when medically necessary,1 which helps with day programs like PHP or IOP.
Who qualifies for FMLA?
Both the employer and your loved one have to meet the rules.1
Could FMLA protect their job?
InteractiveIs the employer a government agency, a school, or a private company with 50+ employees for 20 or more weeks this year or last?

- FMLA likely applies Ask HR for the FMLA paperwork. The treatment provider fills out the medical form.
- FMLA probably doesn't apply, but other protections might The ADA can still require time off as an accommodation (see below). Also check paid leave, disability coverage and state law.
- Ask HR HR can confirm eligibility without knowing the diagnosis. Ask: “Am I eligible for FMLA, and what forms do you need?”
What does FMLA protect?
The job and the health insurance, not the paycheck. They come back to the same job or an equivalent one with equal pay, benefits and terms, and group health coverage continues while they keep paying their usual share.1 The employer can’t punish them for using the leave, with one exception covered in the FAQ below.12
To get some income, they can choose (or the employer can require) to use accrued sick or vacation time during the leave.1 Short-term disability or a state paid leave program may cover part of the rest.
How does the ADA help?
The ADA covers employers with 15 or more employees. It can protect someone in or done with supervised rehab who no longer uses illegal drugs, but not current use.3 A person with alcoholism may be protected, though the employer can still ban drinking at work and hold everyone to the same conduct standards.3 Medication taken under a licensed professional’s supervision isn’t “illegal use of drugs,” so people taking medication for opioid use disorder as prescribed may be covered too.3
It matters most when FMLA doesn’t apply or runs out: extra unpaid leave for necessary treatment can be a reasonable accommodation unless it would cause the employer undue hardship.13
What should we tell the employer?
They don’t have to name the condition to a manager, or even say “FMLA” the first time, but calling in “sick” isn’t enough. The employer needs enough to see the leave may qualify, plus the expected timing and length.1 Something like: “My doctor says I need medical leave for treatment, starting [date], for about [number] weeks. What forms do you need?” If treatment starts on short notice, they only have to tell the employer as soon as practicable, not 30 days ahead.1
The employer can require a medical certification from the provider, generally due within 15 calendar days of the request. The Labor Department’s optional forms are WH-380E for an employee’s own condition and WH-380F for caring for a family member. The form asks for medical facts and may include a diagnosis.1
The employer must keep the certification as a confidential medical record, apart from personnel files, and the direct supervisor can’t be the one who contacts the provider about it.1 A treatment program covered by federal addiction privacy rules generally needs your loved one’s written consent before sharing records with an employer.5 More on how treatment privacy rules work.
Can I take FMLA to care for a family member in treatment?
Yes, if the person in treatment is your spouse, your parent or your child under 18.2 An adult child counts only if a mental or physical disability leaves them unable to care for themselves, and someone who stood in the place of a parent can also count. Siblings, in-laws and unmarried partners aren’t covered under federal FMLA.1
What should we sort out before leave starts?
Before treatment starts: work and leave checklist
- With HR (in writing)
- With the treatment program
- Before returning to work
Workers covered by federal transportation drug and alcohol rules may face extra requirements,3 and so may licensed professionals such as nurses. See treatment for licensed professionals.
Frequently asked questions
Can my loved one be fired after they come back from rehab?
Yes, under an existing drug policy. If the company has an established substance use policy, shared with all employees and applied equally, it can fire someone under it, on FMLA leave or not.2
What if the employer denies leave or retaliates?
Keep copies of every email and form. For FMLA, employees can file a complaint with the Department of Labor or a private lawsuit, generally within two years (three if the violation was willful).1 For the ADA, they can file a discrimination charge with the EEOC.4 Other deadlines apply, so act promptly and consider an employment attorney.
Can they take FMLA more than once for treatment?
Yes, if they’re still eligible and have leave left. The 12 weeks is a total for a 12-month period, and the employer chooses how that period is measured.1 If they need more treatment later, see how families can respond to a relapse.
