An employee must provide the employer with at least 30 days advance notice before the planned paid leave if the qualifying event is foreseeable, such as
- an expected birth, placement for adoption or foster care;
- planned medical treatment for a serious health condition of a family member;
- the planned medical treatment for a serious injury or illness of a covered service member or other known military exigency
If a 30-day advance notice is not practicable (due to, for example, lack of knowledge, a change in circumstances, or a medical emergency), notice must be given as soon as practicable under the facts and circumstances of the qualifying event, ideally within the time required by the employer’s usual and customary notice internal policy.
