The Fear That Stops People Before They Start
For a lot of working professionals, the hardest part of starting treatment isn’t admitting there’s a problem. It’s the assumption that treatment means telling your employer everything, filling out paperwork that feels exposing, and hoping your job survives the process.
That fear is understandable, and it’s also based on a lot of misinformation. Two federal laws, the Family and Medical Leave Act (FMLA) and the Americans with Disabilities Act (ADA), exist specifically to protect employees seeking treatment. Ohio law adds a third layer of protection that many people don’t know about. None of these require you to disclose more than the minimum necessary, and none of them are available to every employee in every workplace. Understanding which one applies to your situation is the first step to making an informed decision, not an anxious guess.
FMLA and ADA Are Not the Same Thing
These two laws get confused constantly, and mixing them up leads people to either overestimate or underestimate their protections. They cover different situations, apply to different employers, and require different things from you.
Quick Comparison: FMLA vs. ADA
| FMLA | ADA | |
| What it provides | Up to 12 weeks of unpaid, job-protected leave per year | Reasonable accommodations to help you keep doing your job |
| Employer size threshold | 50 or more employees within 75 miles of your worksite | 15 or more employees |
| Employee eligibility | Must have worked 12 months and at least 1,250 hours in the past 12 months for that employer | No minimum tenure requirement specified by the law itself |
| What you must disclose | That you have a serious health condition requiring leave | That you have a condition and need a specific change at work |
| Confidentiality | Medical information kept separate from personnel file | Medical information kept separate and confidential |
If your workplace has fewer than 4 employees, federal and Ohio disability protections generally don’t apply, and any leave or accommodation would depend on your employer’s own policies. If your workplace has between 4 and 14 employees, Ohio’s own civil rights law may still protect you even though the federal ADA doesn’t apply yet, more on that below. If your workplace has between 15 and 49 employees, ADA accommodations may be available, but FMLA leave is not. If your workplace has 50 or more employees within 75 miles, and you’ve worked there at least a year with at least 1,250 hours logged, all three protections may apply together.
What FMLA Actually Covers
FMLA provides eligible employees with up to 12 weeks of unpaid, job-protected leave for a serious health condition, which includes many mental health and substance use treatment situations. During that leave, your employer is required to maintain your group health insurance benefits as if you were still working.
FMLA leave doesn’t have to be taken all at once. If your treatment plan allows for it, for example, an intensive outpatient program that runs several evenings a week rather than requiring you to stop working entirely, FMLA leave can sometimes be used intermittently to cover just the time you need for sessions or appointments, rather than a full block of weeks away from work.
Consider a common scenario: a project manager who has worked at a mid-size company for three years needs several weeks of PHP followed by ongoing IOP sessions. Because the company employs well over 50 people and she has logged far more than 1,250 hours over the past year, she qualifies for FMLA. Her employer cannot ask her to name her diagnosis, only to have her provider confirm that she has a serious health condition requiring time away from work. She uses a block of leave for the more intensive phase of treatment, then shifts to intermittent leave for evening IOP sessions as she returns to her regular schedule.
To be eligible, you need to have worked for your employer for at least 12 months and logged at least 1,250 hours during the 12 months before your leave starts, and your employer needs to have at least 50 employees within 75 miles of your worksite. If you don’t meet these thresholds, FMLA does not apply to your situation, though ADA or Ohio protections still might.
What ADA Actually Covers
The ADA works differently. Instead of guaranteeing leave, it requires employers with 15 or more employees to provide reasonable accommodations for employees with a qualifying disability, which can include many mental health conditions and, in some circumstances, substance use disorders, unless doing so would cause significant difficulty or expense for the employer.
A reasonable accommodation could look like an adjusted schedule to attend treatment sessions, permission to use accrued leave for appointments, or a temporary change in duties. Critically, disclosure under the ADA is a choice, not a requirement, unless you’re specifically requesting an accommodation. You are never required to disclose a mental health condition or addiction history simply because you’re an employee. You only need to share what’s necessary to request and receive an accommodation.
One important distinction: the ADA does not protect current illegal drug use. However, someone in recovery from addiction or actively pursuing treatment for a substance use disorder is generally still eligible for protection and accommodation since the law distinguishes between active illegal use and someone seeking or receiving treatment. This includes people taking legally prescribed medication as part of medication-assisted treatment under a provider’s supervision.
Ohio Law Closes the Gap for Smaller Employers
This is the part most people never hear about. The ADA only applies to employers with 15 or more employees, which leaves a lot of Ohio workers unprotected under federal law alone. Ohio Revised Code Chapter 4112 fills that gap. It prohibits disability discrimination by employers with as few as 4 employees, extending accommodation protections to a much wider range of workplaces than the ADA covers on its own.
If you work for a small business in Hilliard, Columbus, or anywhere else in Ohio, and your employer has at least 4 employees, you may still have the right to request a reasonable accommodation for treatment, even if your workplace is too small for the ADA to apply. Complaints under this state law are filed with the Ohio Civil Rights Commission, generally within specific statutory deadlines, so it’s worth talking to your treatment team or an employment attorney if you’re unsure whether your situation qualifies.
What You Actually Have to Tell Your Employer
This is usually the most reassuring part once people understand it clearly. You are not required to explain your diagnosis, your treatment history, or the specifics of what you’re going through. Under FMLA, ADA, and Ohio law alike, you generally only need to communicate that you have a health condition requiring leave or accommodation, not the clinical details behind it.
If you’re requesting FMLA leave, your employer can require a medical certification, typically filled out by your treatment provider, confirming that you have a serious health condition requiring leave. That certification does not have to detail the specific nature of your diagnosis in a way that feels invasive; it needs to establish medical necessity.
If you’re requesting an ADA or Ohio law accommodation, you can use plain language. Saying “I have a medical condition that requires me to attend treatment sessions on Tuesday and Thursday evenings, and I’m requesting a schedule adjustment” is enough to start the conversation. You do not have to say the word “addiction” or name a specific diagnosis unless you choose to.
Whatever information you do share is legally required to be kept confidential, stored separately from your regular personnel file, and is not something your employer can disclose to coworkers or supervisors beyond what’s necessary to implement the accommodation itself. All three of these laws also prohibit your employer from retaliating against you simply for requesting leave or an accommodation, or for exercising your rights under them.
Why Evening and Virtual Treatment Options Change the Calculation
For many working professionals, the entire conversation about FMLA, ADA, or Ohio law becomes less urgent once they realize treatment doesn’t have to interrupt their job at all. Programs built around evening intensive outpatient scheduling or virtual intensive outpatient care mean many people complete treatment without needing to formally disclose anything to their employer, take extended leave, or request a workplace accommodation at all.
That doesn’t mean these legal protections aren’t valuable. It means they’re there if you need them, not a hurdle you have to clear before you’re allowed to get help.
You Don’t Have to Solve This Alone
If you’ve been putting off treatment because you’re not sure how to navigate the legal side of things, that’s a solvable problem, not a reason to keep waiting. A treatment team that works with working professionals regularly can help you understand what documentation you might need and how to structure treatment around your job, not the other way around.

Frequently Asked Questions
Do I have to tell my employer I’m going to rehab or mental health treatment?
You are not required to disclose a specific diagnosis or treatment details to your employer. Disclosure is generally only necessary if you are requesting a reasonable accommodation, and even then, you only need to share what’s necessary to support that request.
How many employees does my company need to have for FMLA to apply?
FMLA applies to private employers with 50 or more employees within 75 miles of your worksite. You also need to have worked for that employer for at least 12 months and logged at least 1,250 hours in the 12 months before your leave begins.
Can I get a workplace accommodation for addiction treatment?
Someone actively seeking or receiving treatment for a substance use disorder is generally eligible for ADA protection and reasonable accommodation, since the law distinguishes between current illegal drug use and a person in treatment or recovery. Accommodations are evaluated on a case-by-case basis with your employer.
What if my employer is too small for the ADA to apply?
Ohio Revised Code Chapter 4112 covers employers with as few as 4 employees, which is a much lower threshold than the ADA’s 15-employee minimum. If your workplace falls in that range, you may still be able to request a reasonable accommodation under state law.
Will my employer know the details of my diagnosis?
No. Medical information related to FMLA leave or ADA and Ohio law accommodations must be kept confidential and stored separately from your regular personnel file. Supervisors may be informed of necessary work restrictions or accommodations, but not the underlying medical details.
Can I do treatment without missing work at all?
For many people, yes. Evening and virtual intensive outpatient programs are specifically designed so treatment happens outside of standard work hours, which means many people complete treatment without needing to request formal leave or disclose anything to their employer.
