A recent settlement between CNN and the EEOC highlights the need for employers to provide gender neutral parental leave policies. The challenged policy provided 10 weeks of paid parental leave to biological mothers and parents who adopted, but only two weeks of paid parental leave to biological fathers. As part of the settlement, CNN changed its policy to provide 6 weeks of paid leave to biological mothers and fathers and to parents who adopt. The lawsuit was based on Title VII. Presumably, the employee was also entitled to unpaid leave under the FMLA. Although, as the NY Times recent article about the CNN settlement and paid leave indicates, many men hesitate to take full advantage of leave available under the FMLA.
