Many dual-career parents are concerned about arrangements for their children during the summer months when the children are at home. There are several ways that employers can cope with this problem: allowing the dual wife or husband to have a lighter load during these months, allowing the dual wife or husband to build up a backlog of working time during other months to relieve them during the summer months, providing facilities on site during the summer months for young children (perhaps using students training in the field of primary education), or some combination of all of these. However, building up a backlog of working time has generally proved difficult to achieve.
