An eligible employee seeking to use FMLA leave must provide 30-day advance notice, unless the need for leave was not foreseeable and/or notice was not practicable. While notice need not be in writing, it is well-advised. When requesting leave, FMLA need not be mentioned by name; notice will be sufficient under the act if the employee provides the employer with enough information to put the employer on notice that FMLA-qualifying leave is needed. An employer may place an employee on involuntary FMLA leave if the employee has given notice to the employer of a qualifying reason for absence that would trigger FMLA rights.
