Accenture, the large professional-services firm, is announcing today that it is allowing mothers and primary caregivers to work locally during the year after they return from parental leave, instead of traveling for out-of-town engagements. Ellyn Shook, Accenture’s chief human-resources officer, said the move was suggested by employees in a parenting group. Ms. Shook said some new-parent employees opted to leave their jobs altogether because they were anxious that their professional-services jobs might entail too much time on the road.
