“Working women today are trying to achieve in the work world what men have achieved all alongbut men have always had the help of a woman at home who took care of all the other details of living! Today the working woman is also that woman at home, and without support services in the workplace and a respect for the work women do within and outside the home, the attempt to do both is taking its tollon women, on men, and on our children.”
