FMLA and Medical Documentation in the US: How Employees Use Job-Protected Leave in Real Life

Short Answer (FMLA medical certification)

FMLA medical certification: FMLA leave is unpaid, job-protected leave for eligible employees with a qualifying reason. You get it through a written process: give written notice, file the certification your employer requires, and file any pay claim separately. A certification supports the leave but does not approve it or pay you.

FMLA leave, for eligible employees of covered employers, is unpaid, job-protected leave for a qualifying reason, and it is obtained through a written process, not through a single conversation or a single document. This guide covers FMLA medical certification in detail. A certification supports the leave, but a certification alone does not approve the leave, and it does not pay the employee during the leave, because pay and job protection are separate filings with separate decision makers.. If you need FMLA leave, start with a written notice, file the certification the program requires, and file any pay claim separately, and keep a written record of each step.

30-second check: is this article for you?

According to the ADA National Network, proper medical documentation is essential for protecting your rights.

Read on if any of these fits:

1. You need time off for your own serious health condition, and you want to know whether FMLA protection applies to you at all.
2. Your leave will be one continuous block plus follow-up appointments spread over weeks, not a single block alone.
3. You told a manager about your leave in conversation, and you are not sure whether that conversation counts as notice.
4. You sent a certification, or a short work note, and you are waiting to hear whether your leave is approved, paid, or both.
5. You want to know, before you file, which step to take when a certification is returned, when a recertification is requested, or when a leave is denied.

If your absence will last only a few days and does not involve a serious health condition, this pillar is not the right map. A short absence follows the short-note process, not the FMLA process.

Helen's surgery, and the conversation that was never filed

According to the U.S. Department of Health & Human Services (HHS), proper medical documentation is essential for protecting your rights.

Helen Park is 41 and works as an office manager at a manufacturing firm. Her regular work means coordinating schedules, handling vendor paperwork, and covering the front office during business hours. Helen has a surgery scheduled in six weeks, with a recovery period that will keep her away from work for four full weeks, followed by follow-up appointments of two hours each, every other Tuesday, for eight weeks after she returns. Her surgeon will support time off for the surgery and for the follow-up appointments, with functional limits during recovery that affect lifting, standing, and driving, and with a review date at the end of the four-week recovery period.

Helen told her direct manager about the surgery in a hallway conversation three weeks ago. She said the surgery was coming, that she would be out for about a month, and that she would need some Tuesday appointments afterward. Her manager said that sounded fine and that they would work it out. Helen left that conversation believing her leave was arranged. Three weeks later, no written notice had been filed, no certification form had been issued, no return date had been recorded, and no pay filing had been started, because a hallway conversation, however friendly, is not a filing. When Helen later asked human resources what was needed, HR explained that FMLA leave requires a written process with its own forms, its own deadlines, and its own decision maker, and that the manager's reassurance, while well meant, had not started any of those processes.

Helen's situation is the reason this pillar is written as a branching map, not as a single form guide. Her leave has two parts that must be filed differently: a continuous four-week block for surgery and recovery, and an intermittent pattern of two-hour appointments every other Tuesday for eight weeks. Each part needs notice, certification that covers it, and a separate decision about pay. A single spoken message, a single short note, or a single certification that covers only the surgery block will not carry the intermittent appointments, will not pay Helen during either part, and will not create a record that protects her if the leave is later disputed. This pillar gives Helen, and any employee in her position, six links, each with one positioning sentence, and a rule for choosing the branch before choosing the form. The sub-articles, not this pillar, carry each link's detail. This pillar does not expand any form's filling instructions, because filling instructions belong to the sub-article and to the program's own form, not to a national map.

The fork, in six links

Do not start with a form. Start with the link you are actually on, because each link has its own branch, its own deadline, and its own decision maker. Answer these questions in order, and stop at the link that fits your situation. If you are on more than one link, as Helen is, work them in order and keep a written record for each one separately.

Link 1: Notice. Have you given your employer written notice that you need leave that may be covered by the FMLA, with enough information for the employer to know the leave may be covered, and have you kept a copy with the date you sent it? If not, you are on Link 1, and no later link can be completed cleanly until this one is. Sub-article: FMLA Notice.

Link 2: Certification. Has your employer issued a certification form, and have you returned a complete and sufficient certification that covers both the continuous block and the intermittent pattern, within the deadline the program sets? If not, you are on Link 2. Sub-article: FMLA Certification.

Link 3: Intermittent leave. Is any part of your leave taken in separate blocks or on a reduced schedule, rather than all at once, and has that pattern been certified and scheduled as intermittent leave, not as a single continuous block? If yes, you are on Link 3, and Helen's Tuesday appointments belong here. Sub-article: FMLA Intermittent Leave.

Link 4: Recertification. Has your employer requested a new certification during the same leave year, because the original certification has expired, the circumstances have changed, or the employer has a permitted reason to ask again? If yes, you are on Link 4, and the original certification does not automatically carry the leave forward. Sub-article: FMLA Recertification.

Link 5: Denial. Has your leave, or any part of it, been denied, returned as incomplete or insufficient, or approved for a shorter period or a narrower pattern than you requested? If yes, you are on Link 5, and the next step is a written response to the specific reason given, not a second copy of the same filing. Sub-article: FMLA Denial.

Link 6: Stacking pay and protection. Have you filed pay separately from protection, naming the pay source, its form, and its deadline, and the protection filing, naming its form and its deadline, and confirmed each one separately in writing? If not, you are on Link 6, and a protection approval must not be read as a pay approval, or the reverse. Sub-article: Stacking FMLA Protection and Pay.

If your leave is a single continuous block with no follow-up pattern, you will use Links 1, 2, and 6, and Links 3, 4, and 5 only if a pattern, a new request, or a denial arises. Helen uses all six links in sequence, because her leave has a continuous block, an intermittent pattern, a certification that must cover both parts, a possible recertification if the pattern extends, a possible denial if any part is returned, and a pay question that must be filed separately from protection. The map that follows explains each link only far enough to tell you which branch you are on. It does not tell you how to fill any form, because that instruction belongs to the sub-article for that link.

---

Link 1: notice, where a conversation becomes a record

Notice is the link Helen missed, and it is the link where the branching starts. The Department of Labor's Fact Sheet #28 on the FMLA states that employees do not have to specifically ask for FMLA leave, but do need to provide enough information so the employer is aware the leave may be covered by the FMLA, and must provide notice to the employer as soon as possible and practical that they will need to use FMLA leave (U.S. Department of Labor: Fact Sheet #28, The Family and Medical Leave Act). That rule has two branches, and Helen's hallway conversation sits on the wrong side of both.

Branch A: notice that gives the employer enough information to know the leave may be covered. A message that states the reason in functional terms, the expected dates, and the pattern, for example a four-week continuous block for surgery and recovery followed by two-hour appointments every other Tuesday for eight weeks, gives the employer that information. Branch B: notice that does not give the employer enough information, for example a hallway remark that surgery is coming and that some Tuesday appointments will follow, with no dates, no pattern, and no written record, does not give the employer a filing to act on, however clear the conversation felt at the time.

The fix for Helen is not to repeat the conversation louder. It is to send a written notice message, with the dates and the pattern stated as calendar dates, to human resources, and to keep a copy with the date it was sent. That written message is the record that starts the employer's FMLA process, including the issuance of a certification form, and it is the record Helen can point to if the leave is later disputed. A spoken message leaves no such record, and a manager's reassurance, however well meant, is not an employer determination. The sub-article on FMLA notice carries the detail: how to word a written notice for a foreseeable leave, how to word a notice for an unforeseeable leave, and what to do when an employer says no notice was received. This pillar does not expand that wording, because wording and timing for notice belong to the sub-article, and because notice deadlines and procedures vary by employer policy in a way a national map cannot state as a single rule.

Link 2: certification, where Form WH-380-E and 29 CFR 825.306 set the proof

Certification is the link where Helen's leave becomes a document the employer can decide, and it is the link where this pillar's concrete object lives. The regulation that sets the content of FMLA medical certification, 29 CFR 825.306, sets out what a certification may require, including the provider's identification, the dates and medical facts supporting the need for leave, work restrictions, and duration. The Department of Labor's guidance for health care providers on FMLA certification explains that a complete and sufficient certification includes the provider's contact information and type of practice, when the serious health condition began and how long it is expected to last, whether the employee is unable to work, for how long, and a description of appropriate medical facts regarding the serious health condition, and that a certification does not need to provide the patient's diagnosis, though it does need appropriate medical facts showing the need for leave (U.S. Department of Labor: Information for Health Care Providers to Complete a Certification under the FMLA).

Form WH-380-E, the Department of Labor's optional form for an employee's own serious health condition, is the form most employers use to collect that certification, and it is the form Helen should expect to receive from her employer after written notice. This pillar does not expand how to fill Form WH-380-E, line by line, because filling instructions belong to the sub-article on FMLA certification and to the form itself. What this pillar does state, as a map rule, is the deadline that governs this link, because a deadline missed is a certification denied, however complete the medical facts are.

That deadline comes from the same Fact Sheet #28 cited above: employers may ask for information from the health care provider before approving FMLA leave and must allow 15 calendar days to provide the information. In other words, once the employer requests certification, Helen has 15 calendar days to provide the certification information, and that 15-calendar-day window is the concrete deadline for Link 2. If the certification is returned as incomplete or insufficient, the employer must give the employee an opportunity to cure the deficiency, under the program's rules, and the sub-article on FMLA certification carries the detail of that cure process. This pillar does not expand it, because the cure process, like the form itself, belongs to the sub-article. The map rule is only this: a certification that covers only the four-week surgery block, and not the two-hour appointments every other Tuesday for eight weeks, does not certify the intermittent pattern, and a certification that is filed after the 15-calendar-day window, without a permitted reason for the delay, does not protect the leave it was meant to support.

Certification is also where the short-note confusion most often appears, and it is worth naming at map level because it decides which document Helen should send. A short work note, stating dates, limits, and a return date, supports a short absence. It does not replace an FMLA certification, because an FMLA certification requires the medical facts, work restrictions, and duration that 29 CFR 825.306 sets out, on the program's form, within the program's deadline. The guide on what a good work doctor's note includes, and what it should leave out explains the short-note format, and the guide on how many sick days can be taken without a doctor's note explains which layer, federal, state, or handbook, sets the number of days that triggers a note. Neither guide replaces Form WH-380-E, and neither guide should be sent to HR in place of a certification. One document, one program, one form, is the rule that keeps Link 2 clean.

Link 3: intermittent leave, where Helen's Tuesdays are a separate pattern

Intermittent leave is the link where Helen's leave most often gets filed wrong, because it looks like a single leave but is in fact two leaves with two patterns. The Department of Labor's FMLA page states that eligible employees may take up to 12 workweeks of leave in a 12-month period for FMLA reasons, and that leave may be taken all at once, or, when medically necessary, in separate blocks of time or by reducing the time worked each day or week (U.S. Department of Labor: Family and Medical Leave Act). Helen's four-week continuous block is the all-at-once part. Her two-hour appointments every other Tuesday for eight weeks are the separate-blocks part, and they must be certified and scheduled as intermittent leave, not as an extension of the continuous block.

Branch A: intermittent leave that is certified for a specific pattern, with the frequency and duration of each absence stated, so that HR can schedule it, track it against the 12-workweek total, and record each two-hour appointment as FMLA time. Branch B: intermittent leave that is described only as "some Tuesday appointments afterward," with no frequency, no duration, and no pattern, so that HR cannot schedule it, cannot track it, and cannot tell whether a given Tuesday absence is FMLA time, paid time off, or an unexcused absence. Helen's hallway conversation was Branch B for the intermittent pattern, even though her surgery block was clear enough to understand in conversation. The fix is a written certification that states the intermittent pattern in numbers: two hours, every other Tuesday, for eight weeks, with the first and last appointment dates stated as calendar dates, so that each appointment can be recorded against the leave total.

Intermittent leave also has a scheduling branch that continuous leave does not. An employee taking intermittent leave for a planned treatment must make a reasonable effort to schedule the treatment so as not to unduly disrupt the employer's operations, subject to the provider's approval, and the employer may require the employee to transfer temporarily to an alternative position with equivalent pay and benefits that better accommodates recurring absences, under the program's rules. Those rules are stated here only as a map warning, not expanded, because their application depends on the treatment schedule, the provider's approval, and the employer's operations, and the sub-article on FMLA intermittent leave carries the detail. The map rule is only this: an intermittent pattern that is not certified as a pattern, and not scheduled as a pattern, will be treated as a series of unrelated absences, and a series of unrelated absences will not be protected as FMLA leave, however real the medical need behind each one is.

Link 4: recertification, where the original certification does not run forever

Recertification is the link where employees most often assume the original certification carries the leave forward, and where that assumption fails when the leave extends, the pattern changes, or the employer has a permitted reason to ask again. The Department of Labor's guidance for health care providers on FMLA certification states that a new medical certification may be requested if the need for FMLA leave continues into a new leave year, and that recertification during the same leave year may be requested generally no more often than every 30 days for a short-term condition, after six months for a longer-term condition, or sooner if, for example, the medical circumstances have changed significantly. Those intervals are stated here only as a map frame, not expanded into a recertification guide, because the sub-article on FMLA recertification carries the detail of when a request is permitted, what it must state, and how long the employee has to respond.

For Helen, the recertification branch matters in two ways. Branch A: her four-week recovery and eight-week appointment pattern are completed within the period her original certification covers, and no recertification is requested, because no trigger has occurred. Branch B: her recovery extends beyond the original certification's duration, or her appointment pattern changes in frequency or duration, or the leave continues into a new leave year, and the employer requests a recertification that states the new duration and the new pattern. Branch B is not a denial, and it is not a penalty. It is a new certification request, with its own deadline, and it must be answered with a new certification that covers the extended or changed pattern, not with a copy of the original certification that no longer matches the leave being taken. An employee who sends the original certification again, in response to a recertification request, has not answered the request, because the request asked for current medical facts and a current duration, not for a repeat of the original filing.

Link 5: denial, where a specific reason gets a specific written response

Denial is the link where employees most often respond with a second copy of the same filing, and where that response fails because it does not answer the reason given. A denial, a return as incomplete or insufficient, or an approval for a shorter period or a narrower pattern than requested, each has a specific reason, and each reason has a specific written response. A certification returned as incomplete is missing information the form requires. A certification returned as insufficient does not support the need for leave as stated, even though the form is filled. A leave denied as ineligible does not meet the program's thresholds. A leave approved for a shorter period does not cover the full pattern requested. Each of those outcomes is a different branch, and each branch requires a different response, whether that response is curing a deficiency, providing additional medical facts that the program permits, correcting an eligibility record, or appealing through the employer's process and, where applicable, through the program's process.

The map rule for Link 5 is only this: ask HR, in writing, for the specific reason, in the program's terms, and for the deadline and the form for responding to that reason, and then respond to that reason, in writing, by that deadline, with the document that reason requires. Do not respond to a denial by resending the original certification, by sending a short work note in place of a certification, or by repeating the hallway conversation that never created a record in the first place. The sub-article on FMLA denial carries the detail: how to read a denial letter, how to cure an incomplete or insufficient certification, and how to appeal a denial through the employer's process. This pillar does not expand that detail, because denial reasons and appeal procedures vary by employer and by program, and a pillar that states one employer's appeal window as a national rule would mislead an employee at a different employer.

Link 6: stacking pay and protection, where two filings must both be confirmed

Stacking is the link where Helen's leave most often looks complete when it is only half complete, because protection and pay are filed through different processes, with different forms, and confirmed by different decision makers. The Department of Labor's FMLA page and Fact Sheet #28 both state the same federal fact that anchors this link: FMLA leave is job-protected, unpaid leave, and employees may use employer-provided paid leave at the same time as FMLA leave, if the reason for the FMLA leave is covered by the employer's paid leave policy, while an employer may also require employees to use their paid leave during FMLA leave. That sentence, read carefully, contains the whole stacking rule: FMLA protection does not pay, employer paid leave does not protect, and the two must be combined deliberately, in writing, for the same absence.

Branch A: protection filed and confirmed, pay filed and confirmed, each on its own form, with its own deadline, so that Helen's four-week block and her eight-week appointment pattern are both protected and, to the extent a pay source covers them, paid. Branch B: protection filed and confirmed, pay never filed, so that Helen's job is protected for the leave period but no paycheck arrives during it, and Helen discovers the gap only when the first pay period passes without pay. Branch C: pay filed and confirmed, protection never filed, so that Helen is paid for time off, whether through paid time off, short-term disability, or another employer benefit, but her job is not protected for that period, because no FMLA filing was ever made or confirmed. Branch C is the branch Helen was closest to after her hallway conversation, because a manager's reassurance about pay or about "working it out" is not a protection filing, and a pay filing, however generous, does not create FMLA protection by itself.

State paid programs, where they apply, are a third stacking source, and they must be filed separately again, on the state program's form, with the state program's deadline, and confirmed separately by the state program. The pillar guide on mental health leave and ADA accommodations at work explains a related stacking problem, where leave, accommodation, and FMLA protection are three different roads, and the pillar guide, The Complete Guide to Doctor's Notes for Work in the US, remains the starting point for what a work note must say and what an employer can legally ask. This pillar does not repeat either guide's detail, because stacking detail, including which pay source covers which part of Helen's leave, belongs to the sub-article on stacking FMLA protection and pay, and to Helen's own benefits documents and state program pages, not to a national map. The map rule is only this: a leave plan is not complete until both filings, protection and pay, are confirmed separately, in writing, each naming its decision maker and its date.

---

The one pit: oral notice as enough, and a certification as approval and pay

The pit this pillar concentrates on, and the only pit it develops in depth, is the double assumption Helen made after her hallway conversation: first, that telling a manager, in conversation, was enough to start FMLA leave, and second, that sending a certification, once issued, would by itself approve the leave and pay her during it. Those two assumptions feel reasonable together, because they mirror how ordinary absences work: tell a manager, send a note, and the absence is excused and, where paid time off applies, paid. FMLA leave does not work that way, and the difference between an ordinary absence and an FMLA leave is the difference between a conversation and a filing, and between a document and a determination.

The first half of the pit, oral notice as enough, fails for three reasons that compound across Helen's leave. First, a spoken message leaves no record of what was said, when it was said, or what dates and pattern were stated, so that when HR later asks for written notice, Helen cannot prove what her manager was told, and her manager cannot prove what was understood, because neither party kept a copy. Second, a spoken message to a direct manager does not necessarily reach human resources, which is the office that issues certification forms, tracks the 12-workweek total, and makes the FMLA determination, so that a manager's reassurance, however sincere, does not start the employer's FMLA process at all. Third, a spoken message that states no dates, no pattern, and no functional limits does not give the employer enough information to know the leave may be covered by the FMLA, which is the standard Fact Sheet #28 sets for notice, so that even if the conversation had been recorded, it would not have satisfied the notice standard for Helen's intermittent pattern, because it never stated the two-hour, every-other-Tuesday, eight-week pattern that pattern requires.

The second half of the pit, a certification as approval and pay, fails for a different set of reasons, and it fails even when the certification itself is complete and sufficient. A certification is medical proof that supports a leave request. It is not an employer determination, because the employer, not the provider, decides whether the employee is eligible, whether the employer is covered, whether the reason qualifies, and whether the leave is approved for the period and pattern requested. A certification that is complete on Form WH-380-E, under 29 CFR 825.306, and returned within the 15-calendar-day window, still requires an employer determination, and that determination may approve the leave, return the certification as incomplete or insufficient, approve a shorter period, or deny the leave, for reasons the certification alone cannot resolve. An employee who assumes a certification equals approval will therefore wait for a paycheck and a protected return date that never arrive, because no determination was ever made, or because the determination made was narrower than the certification requested.

Pay fails for a separate reason, and it fails even when protection is approved. FMLA leave is unpaid, job-protected leave, and pay during FMLA leave comes from a separate source, whether that source is employer-provided paid leave used at the same time as FMLA leave, short-term disability, or a state paid program, each with its own form, its own eligibility rules, and its own deadline. A certification filed for FMLA protection does not file a pay claim, because a pay claim is a different filing, to a different decision maker, on a different form, and an employer that approves FMLA protection has not, by that approval, approved pay. Helen's four-week block and her eight-week appointment pattern therefore each need two confirmations, one for protection and one for pay, and a leave plan that has only one confirmation is not a complete plan. It is half a plan, and the missing half is the half that determines whether Helen is paid during the leave, whether her job is protected during it, or whether, as in Helen's hallway-conversation version, neither half was ever filed at all.

The fix for this pit is a written-record rule, applied at every link, not only at notice. Send written notice, with dates and pattern, and keep a copy with the date it was sent. Return the certification on the program's form, within the 15-calendar-day window, and keep a copy with the date it was returned. Record each intermittent appointment as FMLA time, with its date and duration, and keep that record. Respond to any recertification request or denial in writing, by the deadline given, with the document that request or denial requires, and keep a copy. File pay separately from protection, on the pay source's form, and keep both confirmations, each naming its decision maker and its date. That written record, kept link by link, is the difference between Helen's hallway conversation, which left no filing to point to, and Helen's written leave plan, which leaves a filing at every link, and a confirmation for both protection and pay, before the surgery date arrives.

Privacy, in one paragraph

FMLA filings, like work notes, should state functional limits and time, not a full medical history or a medication list, and the certification form itself sets out what medical facts are required, under 29 CFR 825.306, without requiring a diagnosis. The EEOC's questions and answers on disability-related inquiries explain that an employer may require a doctor's note for sick leave if it has a policy or practice requiring all employees, with and without disabilities, to do so, and that framework applies to ordinary sick leave notes, while FMLA certification follows its own program rules (EEOC: Questions and Answers on Disability-Related Inquiries). Keep each filing on its own form, with only the facts that form requires, and send each filing to the recipient that link names, whether that is human resources for FMLA, a state program for pay, or an employer benefits office for short-term disability. One filing, one form, one recipient, is the privacy rule that keeps FMLA documentation as clean as short work notes.

Where a Rillmont evaluation fits, and where it does not fit

Rillmont serves people in the US and Canada. This article covers US workplaces only. The process is: you complete an online evaluation, a licensed provider reviews it, and if appropriate, a note is issued to your account. That process fits a short work note that supports an absence, when the assessment can establish dates, limits, and a return or review date. It does not, by itself, file FMLA notice, complete Form WH-380-E, certify an intermittent pattern, answer a recertification request, overturn a denial, or file a pay claim, because each of those processes has its own form, its own decision maker, and its own deadline. Use a Rillmont document as supporting material for the link you chose, ready to submit with that link's form, not as a substitute for that form. For the format a short note should follow, see the guide on what a good work doctor's note includes, and what it should leave out, and for the work-note question that often arrives alongside an FMLA filing, when a short absence and a longer leave overlap, see the doctor's note for the USA hub. A short note, an FMLA certification, and a pay claim are three documents, for three decision makers, and none of them files the others.

Your pre-submit action

Do not wait for your surgery date, or for a manager's reassurance, to start the written process, and that written message is the action this pillar leaves Helen with, matched to her situation. Before the date Helen's employer sets for certification, and in any event before her surgery date, Helen should send one written message to human resources, not to her direct manager alone, with four lines, and keep a copy with the date it was sent.

Line one: "I am requesting FMLA leave, and I am giving written notice that my leave may be covered by the FMLA." Line two: the continuous block, as calendar dates, for surgery and recovery, with the return date or review date stated as a calendar date. Line three: the intermittent pattern, as numbers, two hours, every other Tuesday, for eight weeks, with the first and last appointment dates stated as calendar dates. Line four: "Please issue the certification form for this leave, and please confirm in writing the deadline for returning it, and please confirm separately what pay filing, if any, applies to this leave, and what form and deadline that pay filing requires."

That message does four things at once, and it does them in writing, which is the point. It creates a notice record where Helen previously had only a hallway conversation. It states both patterns, continuous and intermittent, so that neither pattern is left to a later assumption. It asks the employer to issue the certification form, so that the 15-calendar-day window can be tracked from a written request date, not from a remembered conversation date. And it asks, in the same message, for the pay filing to be named separately, so that protection and pay are not confused in a single approval. Send that message, keep a copy with the date it was sent, and keep HR's written reply, with the certification form, the deadline, and the pay filing it names, because that reply, kept with the original message, is the written record that turns Helen's leave from a conversation into a filing, and from a filing into a plan that covers both protection and pay.

Frequently asked questions

Does telling my manager in conversation count as FMLA notice?
Not by itself. Employees must provide enough information so the employer is aware the leave may be covered by the FMLA, and must provide notice as soon as possible and practical. A hallway conversation with no dates, no pattern, and no written record does not create a filing, and it does not necessarily reach human resources, which issues certification forms and makes FMLA determinations. Send written notice to human resources, with dates and pattern, and keep a copy with the date it was sent.

Does a completed certification mean my FMLA leave is approved and paid?
No. A certification is medical proof that supports a leave request, on Form WH-380-E under 29 CFR 825.306, and it must be returned within the 15-calendar-day window after the employer's request. Approval is an employer determination, made after the certification is reviewed, and pay is a separate filing, because FMLA leave is unpaid, job-protected leave, and pay comes from employer paid leave, short-term disability, or a state program, each on its own form.

How long do I have to return a certification after my employer requests it?
Employers must allow 15 calendar days to provide the certification information after the employer's request, under the Department of Labor's Fact Sheet #28. If the certification is returned as incomplete or insufficient, the employer must give the employee an opportunity to cure the deficiency under the program's rules, and the sub-article on FMLA certification carries the detail of that cure process.

Does FMLA cover follow-up appointments spread over weeks, or only one continuous block?
FMLA leave may be taken all at once, or, when medically necessary, in separate blocks of time or on a reduced schedule. Helen's two-hour appointments every other Tuesday for eight weeks are an intermittent pattern, and that pattern must be certified and scheduled as intermittent leave, with frequency and duration stated, not described only as some appointments afterward.

What happens if my employer asks for a recertification?
A recertification is a new certification request, not a denial and not a penalty, and it must be answered with a new certification that covers the current duration and pattern, not with a copy of the original certification. A new certification may be requested if the need continues into a new leave year, and recertification during the same leave year may be requested within the intervals the Department of Labor guidance describes, or sooner if medical circumstances have changed significantly.

What should I do if my leave is denied, or approved for less than I requested?
Ask human resources, in writing, for the specific reason, in the program's terms, and for the deadline and the form for responding to that reason. Then respond to that reason, in writing, by that deadline, with the document that reason requires, whether that is curing an incomplete or insufficient certification, correcting an eligibility record, or appealing through the employer's process. Do not respond by resending the original filing or by sending a short work note in place of a certification.

If my FMLA leave is approved, will I be paid during it?
Not automatically. FMLA leave is unpaid, job-protected leave. Pay during FMLA leave comes from a separate filing, whether employer-provided paid leave used at the same time as FMLA leave, short-term disability, or a state paid program, each with its own form, eligibility rules, and deadline. A leave plan is not complete until both protection and pay are confirmed separately, in writing.

What is the first written step I should take for a foreseeable surgery and follow-up appointments?
Send one written message to human resources, with four lines: a statement that you are requesting FMLA leave and giving written notice, the continuous block as calendar dates with a return or review date, the intermittent pattern as numbers with first and last appointment dates, and a request for the employer to issue the certification form, confirm the return deadline in writing, and confirm separately what pay filing, if any, applies. Keep a copy with the date it was sent, and keep human resources' written reply.
