The kids are sick but the boss needs the presentation on her desk by ten. The parent-child kindergarten brunch can't be missed, yet the business meeting beckons. When the only thing she knows for sure is that her day will bring a new set of challenges and priorities to be juggled, how does a stay-at-work mom do it all? Wendy Sachs, stay-at-work mother of two, has interviewed women from every walk of life— from celebrities like makeup maven Bobbi Brown, designer Vera Wang, CNN's Soledad O'Brien, the Ann Curry to everyday moms from all over the country—and has uncovered some inspiring answers. For starters, some stay-at-work moms have given up striving for balance; for true happiness and sanity, integration is the real key. Others have discovered that compartmentalization—wearing different hats at different times of day—is the only way to thrive. For all, the psychological, emotional, and financial payback of work is what keeps them feeling alive; even if they could afford not to work (and many can afford the choice), they wouldn't have it any other way.Demonstrating that a byproduct of having career ambition is a happier marriage and family, will validate the millions of women now attempting to "have it all," or at least some of it all the time. Revealing the keys to staying-at-work, staying sane, staying satisfied, and staying at the heart of her family as well, is a modern working woman's handbook.
