First add your new-born as a dependent through any of the following three portals: the Life and Work events portal, Entitlements, Personal Information. Remember to attach all supporting documentation. The request will go through the workflow to the HR partner for review and approval.
Once HR reviews and approves dependency and a personnel action is processed in Umoja, a new link will be triggered under the Benefits portal. Click on the link and follow the steps to add your new-born to your insurance plans. Make sure to complete the process within 30 days.
