“Do I Have to Grant This Leave?” What Employers Should Know About Doctor’s Notes Requesting Time Off

One of the most common questions I get from clients goes something like this: “My employee handed in note from their doctor saying they need a leave of absence. Do we have to give it to them?”

The short answer is not necessarily, at least not yet. But the note does trigger an important legal process, and how you handle it matters. Here’s a breakdown of what employers actually owe employees when a medical note requesting leave lands on your desk.

Leave Can Be a Reasonable Accommodation

Under both the Americans with Disabilities Act (ADA) and California’s Fair Employment and Housing Act (FEHA), employers have an obligation to provide reasonable accommodations to employees with a qualifying physical or mental disability, unless doing so would impose an undue hardship on the business. A leave of absence can itself qualify as a reasonable accommodation.

That doesn’t mean every leave request must be granted automatically. It means the request opens up an interactive process that both sides are supposed to engage in, and that process starts with figuring out what’s actually going on medically, and what the employee actually needs.

The Problem With Generic Doctor’s Notes

Here’s where things get frustrating for employers. A lot of the notes that show up are vague to the point of being almost meaningless. Something like “Patient needs to be off work for medical reasons — please excuse for 6 weeks” doesn’t tell an employer anything about whether the employee has a condition that qualifies as a disability, what the employee’s actual limitations are, or whether leave is even the right accommodation as opposed to something else, such as modified duties, a schedule change, or some other adjustment.

Unfortunately, this kind of boilerplate note is common. Healthcare providers are often simply responding to what their patient asked for, without necessarily turning their mind to what the employer legally needs to make an informed decision.

What Employers Can Actually Ask For

The good news is that employers aren’t stuck accepting a rubber-stamped note at face value. You’re entitled to request reasonable medical documentation before deciding on the accommodation request, and that documentation should address:

• Confirmation that the employee has a physical or mental condition that limits a major life activity, or a medical condition triggering coverage;
• A description of why the employee needs a reasonable accommodation — i.e., how the condition affects their ability to do the job;
• The provider’s opinion on what accommodations, if any, are medically necessary to address the employee’s limitations at work (this is the piece that’s often missing from generic notes, and it’s the piece that actually helps you evaluate the request); and
• Whether the accommodation is temporary or ongoing — and if temporary, the expected duration.

One important boundary is that employers should not request the underlying diagnosis. You’re entitled to enough information to evaluate the limitation and the proposed accommodation — not the employee’s private medical details.

Until the employee provides documentation sufficient to address these points, the employer has no obligation to grant the requested leave. Once it’s provided, you’re in a much better position to evaluate whether the leave (or some alternative accommodation) makes sense, and to have a meaningful interactive process conversation with the employee rather than guessing at what they actually need.

A Note on FMLA and CFRA

If the leave request is instead being made under the federal Family and Medical Leave Act (FMLA) or California’s parallel Family Rights Act (CFRA), the same basic logic applies. Employers can require medical certification supporting the need for leave, and a vague or incomplete note doesn’t obligate the employer to grant leave until adequate certification is provided. That said, FMLA and CFRA come with their own specific certification requirements, timelines, and procedures that differ in the details from the ADA/FEHA accommodation process. The two frameworks often overlap in practice. The same leave request can implicate both,  but they’re legally distinct, and treating them as identical can create compliance gaps.

The Bottom Line

A doctor’s note requesting leave isn’t a rubber stamp, and employers aren’t required to just take it on faith. But it also isn’t something you can simply ignore or deny outright. The right response is to request documentation that actually answers the questions that matter, engage genuinely in the interactive process once you have it, and make a documented, individualized decision from there. Employers who skip this step, either by granting vague requests without question or denying them outright, tend to be the ones who end up in disputes later.
