29 C.F.R. § 825.101 : Labor — REGULATIONS RELATING TO LABOR — WAGE AND HOUR DIVISION, DEPARTMENT OF LABOR — OTHER LAWS — THE FAMILY AND MEDICAL LEAVE ACT OF 1993 — COVERAGE UNDER THE FAMILY AND MEDICAL LEAVE ACT — Purpose of the Act

(a) FMLA is intended to allow employees to balance their work and family life by taking reasonable unpaid leave for medical reasons, for the birth or adoption of a child, for the care of a child, spouse, or parent who has a serious health condition, for the care of a covered servicemember with a serious injury or illness, or because of a qualifying exigency arising out of the fact that the employee's spouse, son, daughter, or parent is a military member on covered active duty or call to covered active duty status. The Act is intended to balance the demands of the workplace with the needs of families, to promote the stability and economic security of families, and to promote national interests in preserving family integrity. It was intended that the Act accomplish these purposes in a manner that accommodates the legitimate interests of employers, and in a manner consistent with the Equal Protection Clause of the Fourteenth Amendment in minimizing the potential for employment discrimination on the basis of sex, while promoting equal employment opportunity for men and women.
(b) The FMLA was predicated on two fundamental concerns-the needs of the American workforce, and the development of high-performance organizations. Increasingly, America's children and elderly are dependent upon family members who must spend long hours at work. When a family emergency arises, requiring workers to attend to seriously-ill children or parents, or to newly-born or adopted infants, or even to their own serious illness, workers need reassurance that they will not be asked to choose between continuing their employment, and meeting their personal and family obligations or tending to vital needs at home.
(c) The FMLA is both intended and expected to benefit employers as well as their employees. A direct correlation exists between stability in the family and productivity in the workplace. FMLA will encourage the development of high-performance organizations. When workers can count on durable links to their workplace they are able to make their own full commitments to their jobs. The record of hearings on family and medical leave indicate the powerful productive advantages of stable workplace relationships, and the comparatively small costs of guaranteeing that those relationships will not be dissolved while workers attend to pressing family health obligations or their own serious illness.
