If you've already sent your enrollment materials to us, call our Customer Care Center at 877-456-6670 Mon - Fri, 9am-7pm EST. Usually, such events constitute a "qualifying event" that will allow the affected employee to change his/her coverage within a specified time period.
 
If you have not yet sent in your enrollment package and an employee leaves the company, delete the employee from your Enrollment Center.
 
If you have not yet sent in your enrollment package and a new employee joins the company, add the new employee to the Enrollment Center and have him or her complete enrollment online.
