Family Leave for Parental Involvement in Education Act This bill provides eligible employees to up to 48 hours of additional annual family and medical leave to attend activities related to a school or community organization attended by an employee's child or grandchild. Employees may use not more than 8 hours of such leave per 30-day period and must notify employers in advance of using such leave. This leave also is available to federal employees.
