How to Handle a Leave Extension Request

At some point, almost every HR professional faces this situation: an employee on leave reaches out to say they won’t be ready to come back when expected. Maybe their doctor extended the recovery timeline. Maybe a family situation took a turn. Whatever the reason, a leave extension request can feel like a lot to manage, especially if you’ve never dealt with one before.

The good news is that if you have a clear process, it’s manageable. Here’s how to work through it.

Understand What Type of Leave You’re Working With

Before you do anything else, make sure you know what kind of leave the employee is currently on. This determines what obligations you have and what options you can offer.

• FMLA gives eligible employees up to 12 weeks of job-protected, unpaid leave per year (or 26 weeks for military caregiver leave). 

• State-protected leave can add additional protections on top of FMLA. In California, CFRA and PDL have their own rules that often run parallel to or extend beyond federal law. 

• Company-provided leave is whatever your policy offers beyond what the law requires.

  
  

Knowing which category you’re working in shapes everything that follows.

What Documentation to Ask for Before You Approve Anything

Any leave extension should be supported by documentation. Make that expectation clear upfront.

For medical leave extensions, ask for an updated certification from the employee’s healthcare provider confirming the continued need for leave, the expected duration, and any work restrictions. If the original certification has expired or the condition has changed, a fresh one is appropriate to require.

For non-medical leave extensions, the documentation will depend on the reason. An updated provider certification works when a family member’s condition is involved. A written statement from the employee explaining the need for additional time is a reasonable starting point for other situations.

Give employees a clear deadline to provide documentation. Fifteen calendar days is a commonly used benchmark, though you should check your policy and any applicable state requirements. Put the deadline in writing.

How to Communicate Your Decision

Once you’ve reviewed the documentation and made a decision, put it in writing. Even if you spoke with the employee by phone first, always follow up with a letter or email. Your written communication should cover:

• Whether the extension is approved or denied

• The new expected return-to-work date (if approved)

• What type of leave covers the extension period

• Benefits status during the extension

• What the employee needs to do before returning to work

Keep the tone clear and supportive. Employees on leave are often dealing with something genuinely difficult, and how you communicate with them during this time matters.

When an Extension May Not Be Approved

There are situations where approving an extension isn’t possible, such as the employee has exhausted all available leave, documentation hasn’t been provided, or the role simply cannot stay open any longer.

If you’re in this situation, don’t move toward a denial or separation without first working through the accommodation analysis. Even when all leave is exhausted, additional unpaid leave can sometimes qualify as a reasonable accommodation under the ADA. California employers should also factor in FEHA, which applies to employers with 5 or more employees (compared to the ADA’s 15-employee threshold) and has its own interactive process requirements enforced by the CRD. If you’re not sure whether an accommodation obligation exists, that’s a good reason to loop in your employment attorney before you act.

If separation does become necessary, approach it carefully, document the full picture, and get legal counsel involved before making the call.

Updating Payroll, Benefits, and Internal Tracking

An approved extension means a few internal updates need to happen.

Payroll: Confirm whether the extension period is paid or unpaid and update accordingly. If the employee is receiving state disability or paid family leave benefits, make sure you understand how those coordinate with any company pay continuation.

Benefits: Under FMLA, the employer must maintain the employee’s group health coverage during leave on the same terms as if they were actively working. Once protected leave is exhausted, that obligation may no longer apply. If the employee’s coverage is going to lapse, they need to know in writing before it happens, and you should be prepared to issue a COBRA election notice (or Cal-COBRA notice for California employers with fewer than 20 employees). This step is easy to overlook and important not to miss.

Internal tracking: Update your HRIS with the new return date and document the approval. Notify the employee’s manager and payroll of the updated timeline, sharing only what’s necessary on the medical details.

When Leave Runs Out and the Employee Still Can’t Return

When an employee has exhausted every available leave option and still cannot return, work through these steps before making any decisions.

First, check whether any ADA or FEHA accommodation could make a return possible, whether that’s modified duties, a reduced schedule, or a remote arrangement. Sometimes the barrier to returning isn’t the condition itself but a specific job requirement.

Second, consider whether a short additional unpaid leave is feasible if the employee has a realistic return date on the near horizon.

If neither option works and separation becomes necessary, document everything and get legal counsel involved. Terminations in a leave context carry real risk if the process isn’t airtight.

When an Employee Keeps Asking for More Time

Evaluate each request on its own merits with current documentation. You’re not obligated to keep approving extensions indefinitely, but decisions shouldn’t be driven by frustration. Ask for updated certification with each request and set clear return-to-work expectations every time.

If no definitive return date is in sight, you’re likely back in accommodation territory, and possibly approaching a broader conversation about the employee’s ability to return at all. Document every request, every response, and every conversation. A thorough file is your best protection if anything is ever questioned later.

Final Thoughts

Leave extension requests don’t have to be overwhelming. Stay consistent, document everything, and know when to bring in legal support. If you’re managing HR on your own or early in your career, that last piece is especially important. You don’t have to have every answer. Knowing when to call your employment attorney is part of the job.
