If Your Leave Might Qualify for FMLA

This is general information, not legal advice.

Notice: for unforeseeable leave, notice is due as soon as practicable under the facts and circumstances, according to the U.S. Department of Labor.
What to say: give enough information for the employer to reasonably determine whether the FMLA may apply, such as being unable to perform your job functions or being hospitalized overnight.
Call-in rules: you must comply with your employer’s call-in procedures unless unusual circumstances prevent you from doing so.
Naming the law: for a first-time qualifying reason, you do not need to mention the FMLA.
Certification: an employer may require a health care provider’s certification and must allow at least 15 calendar days to obtain it.
Eligibility: 12 months with the employer, 1,250 hours in the previous 12 months and a work location with 50 or more employees within 75 miles.

Mistakes to Avoid

Sending only an email when a call is required. Follow the call-in rules.
Sharing too much private detail. A general reason is enough.
Leaving the return date unclear. Give a date or an update time.
Forgetting urgent work. Name a coworker or point to your notes.
Going silent. Send the update you promised.
Forgetting to keep a copy.

Frequently Asked Questions

How soon should I tell my manager about unplanned leave?

As early as you can, ideally before your shift starts. The U.S. Department of Labor says an employee with unforeseeable FMLA-qualifying leave must give notice as soon as practicable under the facts and circumstances of the case.

Should I email or call my manager?

Follow your employer’s call-in procedure. Many workplaces want a call or message to a specific person. The Department of Labor says an employee must comply with the employer’s call-in procedures unless unusual circumstances prevent it. An email can follow as a written record.

How much should I say about the reason?

Keep it brief. Saying you are unwell or that a family matter needs your attention is usually enough. Share more only if you choose to or the employer requires it.

What should the subject line say?

Make it clear and short, such as Unplanned Leave Today, Your Name. Your manager should know what the email is about before opening it.

Do I need to mention the Family and Medical Leave Act?

Not necessarily. The Department of Labor says that for a first-time FMLA-qualifying reason, an employee need not expressly assert FMLA rights or even mention the FMLA, but must give enough information for the employer to reasonably determine whether it may apply.

Who is eligible for FMLA leave?

According to the Department of Labor, an employee must have worked for the employer for 12 months, have worked 1,250 hours in the 12 months before leave starts and work at a location with 50 or more employees within 75 miles. Covered employers must grant up to 12 workweeks of unpaid, job-protected leave in a 12-month period for qualifying reasons.

Can my employer ask for a doctor’s note?

Often, yes. For FMLA leave, the Department of Labor says an employer may require certification from a health care provider and must allow at least 15 calendar days to obtain it. Other leave follows your employer’s policy and your state’s rules.

What if I cannot say how long I will be gone?

Say so honestly, and promise a specific update, for example by 4:00 p.m. today. Then send that update on time.

Should I send a follow-up when I return?

It is a courteous step. A short email thanks your manager, confirms you are back and says how you will catch up.

Can I use these samples for other types of leave?

Yes. Change the reason and the details to match your situation, and check your employer’s policy for the type of leave you need.

Conclusion

An unplanned absence is easier on everyone when you tell your manager early, keep the message short and polite, and say what happens next. Use the builder above to write yours.
