What to Tell Your Employer When You Go on SDI for Mental Health (and What You’re Not Required to Disclose)

By Michael Steiner | SDI Advisor

Of all the questions we hear at SDI Advisor, this might be the one that causes the most quiet anxiety: what exactly am I supposed to tell my employer?

It makes sense that this question carries weight. Depression, anxiety, and PTSD are deeply personal. Many people worry that disclosing a mental health condition will change how they’re seen at work — that a manager who knows “depression” instead of “medical leave” will treat them differently, pass them over, or quietly push them out once they return. That fear is not irrational, and we’re not going to pretend it is.

Here’s the good news, and it’s genuinely good news: California law gives you more privacy than most people assume. You are not required to hand your employer a diagnosis. In most situations, you’re not required to explain your symptoms, your treatment, or even the general category of condition you’re dealing with. What you typically need to provide is much narrower — enough for your employer to understand that you have a qualifying medical reason for leave and what functional limitations apply, not the clinical story behind it.

This guide walks through exactly what you’re required to disclose, what you’re not, who’s allowed to know what, and how to handle the conversation with your employer in a way that protects both your privacy and your claim.

The Core Principle: Functional Limitations, Not Diagnosis

The single most useful thing to understand here is the difference between two categories of information:

Functional limitation information — what you can and can’t do, and for how long. “I am unable to perform my regular work duties starting [date], for an estimated period of [duration], due to a medical condition.” This is what your employer is generally entitled to know.

Diagnostic information — the specific clinical name of your condition, your symptoms, your treatment plan, your medication, your therapy notes. This is generally not something your employer can require you to disclose.

Under California law — specifically the Confidentiality of Medical Information Act (CMIA), which governs employee medical privacy far more directly than the federal HIPAA law most people assume applies here — your employer can request documentation sufficient to verify your need for leave and understand any work restrictions. They cannot demand your full medical history, and they cannot compel you to name your diagnosis as a condition of approving leave or an accommodation.

In practice, this means a note or certification that says “patient has a medical condition that prevents work for an estimated 8 weeks, with possible need for a modified return-to-work schedule” can be legally sufficient. It does not need to say “patient has been diagnosed with major depressive disorder, recurrent, severe, with anxious distress.”

What HIPAA Actually Does (and Doesn’t) Protect Here

People bring up HIPAA constantly in this context, and it’s worth clearing up a common misconception: HIPAA does not generally apply to your employer. HIPAA governs healthcare providers, health plans, and healthcare clearinghouses — what’s called “covered entities.” Your employer, in its role as your employer, is not one of those.

What actually protects your privacy at work in California is a combination of:

The California Confidentiality of Medical Information Act (CMIA), which restricts what your employer can do with any medical information it does receive — it can’t be disclosed to coworkers or used outside the specific purpose it was collected for (administering your leave, accommodation, or benefits), without your written authorization.

FMLA and CFRA’s own confidentiality requirements, which obligate your employer to keep any medical information gathered during the leave process separate from your general personnel file and limit its use to administering the leave itself.

FEHA’s accommodation framework, under which information related to a disability accommodation request is similarly meant to stay confidential and limited to those who need to know it to administer the accommodation.

The upshot: even when you do share medical information with your employer to support a leave or accommodation, the law restricts what they can do with it afterward. Your manager generally shouldn’t have access to your underlying diagnosis even if HR does, and coworkers shouldn’t have access to any of it.

What You Have to Disclose — and to Whom

This depends on what you’re requesting, so it’s worth breaking down by scenario.

If you’re just telling your employer you need to be out

At the most basic level, notifying your employer that you need medical leave doesn’t require disclosing anything about the underlying condition. “I have a medical situation and need to take leave starting [date]” is a complete and sufficient notification on its own. Your employer can ask for more in order to administer FMLA, CFRA, or a FEHA accommodation — but the initial notice doesn’t require a diagnosis.

If you’re requesting FMLA or CFRA leave

Your employer can require a medical certification, but the certification form is specifically designed to avoid requiring a diagnosis. It typically asks your provider to confirm: that you have a serious health condition, the date it began, the probable duration, and whether you’re unable to perform the essential functions of your job. None of those fields require naming the condition. Your provider can complete the certification using functional language — “patient is unable to perform regular job duties due to a medical condition” — without ever writing “depression” or “PTSD” on the form.

For guidance on how this works specifically for an SDI medical certification, see our guide on who can certify your California SDI claim.

If you’re requesting a FEHA reasonable accommodation

This is where slightly more disclosure may genuinely be necessary — not because the law requires it as a baseline, but because the interactive process is a two-way conversation about what limitations exist and what accommodations would address them. If you’re asking for a modified schedule because concentration is difficult in the afternoons, your employer may reasonably need to understand that specific limitation to identify an effective accommodation. Even here, though, you’re disclosing the functional limitation — not necessarily the diagnosis driving it.

If you’re filing for SDI itself

This one’s worth being precise about: your SDI claim does not go through your employer at all. It’s filed directly with the EDD. Your employer may be contacted to verify your wage history and employment dates, but they don’t see your medical certification, your diagnosis, or any clinical details. The EDD does not routinely notify employers when an SDI claim is approved or when payments are made. Whatever your employer knows about your situation comes only from what you’ve told them directly about your leave — not from your SDI filing.

See our step-by-step SDI application guide for how the SDI side works independently of any conversation with your employer.

What a Privacy-Protective Disclosure Actually Sounds Like

If you want language that gives your employer what they need without disclosing your diagnosis, something like this generally works:

“I’m dealing with a medical condition that’s affecting my ability to perform my regular job duties. I’ll be taking medical leave starting [date], and my provider estimates I’ll need approximately [duration]. I’ll have documentation for HR as needed, and I’d appreciate keeping the details private beyond what’s necessary to process the leave.”

This communicates exactly what your employer is entitled to — that a genuine medical condition exists, what the practical impact is, and a general timeline — without naming the condition. If HR or your manager pushes for more specificity, it’s reasonable to ask why that level of detail is necessary for processing your leave, and to direct clinical questions to your provider’s certification rather than answering them yourself in conversation.

When You Might Choose to Disclose More — and Why That’s a Personal Decision

Some people choose to tell their employer more than the law requires — naming the specific condition, explaining what’s been happening, being candid about the severity. There are real reasons people do this: it can foster understanding from a supportive manager, make returning to work feel less like hiding something, or simply reflect how someone wants to handle their own situation.

This is entirely your call, and there’s no right answer. What matters is that it’s a choice you’re making with accurate information about what’s actually required versus what’s optional. Some things worth weighing:

A more generous, detailed disclosure to a genuinely supportive manager can sometimes lead to a smoother return-to-work conversation, because the manager already understands the broad shape of what you’re navigating.

A more guarded disclosure protects you in situations where you’re not confident about how the information will be handled — a newer manager, a workplace culture that hasn’t always handled sensitive situations well, or simply a personal preference for keeping medical matters separate from professional ones.

Neither approach is wrong. What you tell HR doesn’t have to match exactly what you tell your direct manager, and what you put in writing doesn’t have to be more detailed than what’s legally required just because someone asks a follow-up question.

What If Your Employer Asks for More Than They’re Entitled To?

This happens more than it should, often not out of bad faith but because HR staff and managers aren’t always trained on the specific limits of what they can request.

You can decline to provide diagnostic detail and instead point to your provider’s certification. “My provider’s certification documents what’s needed for the leave — I’d prefer to keep the clinical details private” is a reasonable and legally supportable response.

Your provider’s certification doesn’t need to include a diagnosis to be valid for FMLA, CFRA, or your SDI claim. If your provider’s office is asking what to include, they can use functional language without naming the condition. For more on what a strong certification looks like, see our guide on Form DE 2501 and what the EDD actually needs to see.

Repeated or escalating pressure to disclose more than required can itself raise concerns about whether your employer is administering the leave process in good faith. If this is happening to you, it’s worth documenting the requests and, if it continues, consulting a California employment attorney.

What About Coworkers?

A separate and very common worry: what will coworkers know, and what will they assume?

Legally, your employer is not supposed to disclose your medical information — including the fact that you’re out for a medical reason, let alone any specifics — to coworkers without your authorization. In practice, most workplaces handle absences with something generic: “[Name] is out on a leave of absence” or simply silence, with no explanation given at all. Your manager may need to manage workload and coverage without revealing why you’re out, and that’s both legally required and entirely normal.

What coworkers infer on their own is a different matter — people sometimes guess, especially if your absence is sudden or extended. But that’s speculation on their part, not information your employer is supposed to be sharing. If you become aware that your medical information has been shared with coworkers without your authorization, that’s a potential CMIA violation worth raising with HR directly, and if unresolved, with an employment attorney.

How This Connects to Your SDI Claim

One of the most important things to understand is that your SDI claim and your employer’s leave administration are completely separate processes. You file your SDI claim directly with the EDD — your employer doesn’t see it, doesn’t approve it, and has no role in whether you receive benefits. The only time your employer is involved in the SDI process at all is when the EDD contacts them to verify your employment dates and wage history. That verification doesn’t reveal your diagnosis or anything about your medical condition.

This means you can be receiving SDI payments for depression or anxiety without your employer knowing the specific nature of your condition — as long as you’ve managed your leave notification carefully on your end.

For the SDI side of this process — how to apply, what your provider needs to certify, and what happens after you’re approved — see our complete guide to applying for California SDI and our overview of what to expect after your claim is approved.

How This Interacts With Returning to Work

When you’re ready to return — whether after 8 weeks or after the better part of a year on SDI — the same privacy principles generally apply. Your employer can require a fitness-for-duty certification confirming you’re able to return and noting any ongoing restrictions or accommodations needed. They generally cannot require you to disclose your full treatment history or demand specifics about your ongoing care as a condition of returning.

If you’re returning with some ongoing limitations — needing a modified schedule for a period, or specific accommodations to ease the transition — that’s again handled through the functional-limitation framework. “Patient may return to work with the following restrictions: [specific limitations], to be reevaluated in [timeframe]” is the kind of language that supports a smooth return without requiring you to re-explain your diagnosis all over again.

Frequently Asked Questions

Does my employer find out my SDI claim is for a mental health condition specifically? No, not through the SDI claim itself. SDI is filed directly with the EDD, and your employer doesn’t see your medical certification or diagnosis through that process. Whatever they know comes only from what you’ve chosen to tell them directly about your leave.

Can my employer require me to name my diagnosis before approving FMLA or CFRA leave? No. The medical certification required for FMLA and CFRA can be completed using functional language describing your limitations and expected duration, without naming the specific condition.

What if my company’s HR form has a field that asks for my diagnosis? You’re generally not required to fill that field in to receive leave you otherwise qualify for. Many companies use generic forms that ask for more than the law requires; you can leave diagnosis fields blank or write “see provider certification” and direct them to the functional-limitation documentation instead.

Is it illegal for my manager to tell coworkers why I’m out? Your employer is required to keep your medical information confidential and generally shouldn’t be disclosing the reason for your absence to coworkers without your authorization. If this happens, it’s worth raising directly with HR.

Will disclosing a mental health condition affect my job security? Disclosing a disability or requesting leave or accommodation for one is legally protected activity — retaliating against you for it violates FMLA, CFRA, and FEHA. That said, the law’s existence doesn’t eliminate every real-world risk, which is exactly why understanding what you’re not required to disclose matters.

Do I need to tell my employer I’m receiving SDI payments? No. Your SDI claim and your employer’s leave administration are separate. You don’t need to tell your employer you’re receiving SDI benefits, though many people mention they’re “on disability” in a general sense — that’s a personal choice, not a legal requirement.

Can my employer contact my doctor directly to ask about my condition? Generally only to verify that a certification or note is authentic — confirming dates and that the document came from their office — not to discuss your diagnosis, symptoms, or treatment. Your provider should not discuss clinical details with your employer without your specific written authorization.

What if I don’t have a provider yet — do I need one before telling my employer about my leave? You don’t need a provider to notify your employer that you need leave. But you will need one to get your SDI claim approved and to support any FMLA/CFRA request. See our guide on who can certify your California SDI claim for what type of provider you need.

A Note on Why This Matters Beyond the Legal Technicalities

We talk to a lot of people who put off filing for SDI, or who hesitate to take the leave they need, specifically because they’re afraid of what disclosing a mental health condition will mean for how they’re seen at work. That fear is real, and we’re not going to tell you it’s entirely unfounded — workplace stigma around mental health still exists, even with all the legal protections in place.

But understanding exactly what you’re required to share — and how much narrower that is than most people assume — can make the decision to take the leave you need a little less daunting. You don’t have to choose between protecting your privacy and getting the support you’re entitled to. In most situations, you can have both.
