This important change in women' s life has only recently begun to have its full effect on women's economic position. Even a few years ago most girls left school and took a full-time job. However, when they married, they usually left work at once and never returned to it. Today the school-leaving age is sixteen, many girls stay at school after that age, and though women marry younger, more married women stay at work at least until shortly before their first child is born. Very many more afterwards return to full or part-time work. Such changes have led to a new relationship in marriage, with the husband accepting a greater share of the duties and satisfactions of family life.
