In 1991, Ferber co-edited with Brigid O’Farrell "Work and Families: Policies for a Changing Work Force." Ferber and O’Farrell address how more women have entered the work force, which results in both parents being employed. The result is that the burden on familial responsibilities and childcare must be readjusted if women are now entering the work force because work often conflicts with family duties, so employers must make adjustments in benefits, for example, to redress the changing situations of their employees.
