The FMLA permits an employer to require that you submit a timely, complete, and sufficient certification to support a request for FMLA leave due to a qualifying exigency. Several questions on this form seek a response as to the frequency or duration of the qualifying exigency. Be as specific as you can; terms such as "unknown," or "indeterminate" may not be sufficient to determine FMLA coverage. Your response is required to obtain a benefit. 29 CFR 825.310. While you are not required to provide this information, failure to do so may result in a denial of your request for FMLA leave. Your employer must give you at least 15 calendar days to return this form to your employer.
