As soon as practicable
As soon as practicable means as soon as both possible and practical, taking into account all of the facts and circumstances in the individual case. When an employee becomes aware of a need for FMLA leave less than 30 days in advance, it should be practicable for the employee to provide notice of the need for leave either the same day or the next business day. In all cases, however, the determination of when an employee could practicably provide notice must take into account the individual facts and circumstances.
