The recently enacted Family and Medical Leave Act requires larger employers to provide eligible employees with up to twelve weeks of unpaid leave for certain medical and family-related reasons. This article addresses who the law applies to; the circumstances when leave must be granted; how the leave period is supposed to be scheduled; various notice, scheduling, medical certification, and reporting requirements; reinstatement and continuation-of-benefits requirements, and other key provisions of the Act. The basic requirements of the Act are not complicated, but certain issues that are not addressed by the Act or its legislative history-such as what qualifies as a serious health condition justifying a leave, when an intermittent or reduced schedule leave may be taken and how such schedules are determined, and how differences with state family and medical leave laws are to be reconciled-will have to be resolved by administrative regulation or litigation.
