§ 825.304 Employee failure to provide notice.
(a) Proper notice required. In all cases, in order for the onset of an employee's FMLA leave to be delayed due to lack of required notice, it must be clear that the employee had actual notice of the FMLA notice requirements. This condition would be satisfied by the employer's proper posting of the required notice at the worksite where the employee is employed and the employer's provision of the required notice in either an employee handbook or employee distribution, as required by § 825.300.
(b) Foreseeable leave—30 days. When the need for FMLA leave is foreseeable at least 30 days in advance and an employee fails to give timely advance notice with no reasonable excuse, the employer may delay FMLA coverage until 30 days after the date the employee provides notice. The need for leave and the approximate date leave would be taken must have been clearly foreseeable to the employee 30 days in advance of the leave. For example, knowledge that an employee would receive a telephone call about the availability of a child for adoption at some unknown point in the future would not be sufficient to establish the leave was clearly foreseeable 30 days in advance.
