One Pacific Bell managers, Sandy Hale, manager of media relations, spends four days a week working at home, and has been doing so since her second baby was born recently. It seems the ideal answer for spending more time with her family while continuing her career. She places her two children with a babysitter next door and visits them twice a day. Doing that keeps her close to the children, yet saves her two hours a day in commuting. That conserves energy-for body and car, she says.
