The bill entitles an employee who is a domestic partner, next of kin of a member of the Armed Forces, or any individual whose close association is like a family relationship, regardless of biological or legal relationship, to take leave to care for the service member. The bill entitles private sector and federal employees to take additional leave to participate in or attend their children's and grandchildren's school or community organization activities, meet routine family medical care needs, or care for their elderly relatives.
