This bill amends the Family and Medical Leave Act to allow eligible employees to take up to 48 hours of unpaid leave per year, in increments of no more than 8 hours per 30-day period, to participate in or attend their children's and grandchildren's school activities and educational events. The leave covers attendance at school conferences and activities sponsored by schools, Head Start programs, child care facilities, and nonprofit community organizations like sports leagues and scouting groups. Employees must provide at least seven days' notice when requesting this leave, and employers can require certification to support the request. The bill applies to both private-sector employees covered by the Family and Medical Leave Act and federal employees, and allows workers to use their accrued paid vacation, personal, or sick leave to cover the unpaid parental involvement leave if they choose or if employers require it.
