The main purpose of this legislation is to amend the Family and Medical Leave Act of 1993 to allow employees to take leave in the event of a spontaneous loss of an unborn child. This law aims to provide support for parents who experience such a loss, recognizing the emotional and physical toll it can take. Key provisions of the law include defining "spontaneous loss of an unborn child" as an unplanned loss that does not result from any purposeful act. It grants employees the right to take leave for this reason, similar to other family and medical leave provisions.
