Adobe defines primary caregiver as the parent who takes the main responsibility to care for a child during work hours. The non-primary caregiver is the other parent. So if a gay couple working at Adobe adopts a baby, one of them would get to take 16 weeks off and the other, four weeks, depending on who cares for the child during work hours. The new policy applies to Adobe's 6,000 U.S. employees and takes effect Nov. 1. San Jose, California-based Adobe makes popular software such as Photoshop and Acrobat. "Caring for yourself and your family at home helps you be your best at work. But in the U.S., government mandates for paid leave are currently slim to nonexistent," Donna Morris, senior vice president of people and places at Adobe, wrote in a blog post Monday. "That means companies must navigate the tough balance between supporting employees during major life events and meeting business goals. Too often, employees have not had the support they need."
