For years, career women have heard that it’s fine for them to quit their jobs in order to become stay-at-home moms. They’re told that it’s the best thing for their children and eventually they can make their way back into the workforce when their kids get old enough.

But a new book - called The Feminine Mistake - disagrees with all that. The author, Leslie Bennetts, says that women should not quit their jobs when they have children. The theory is that if women depend on their spouses, it could have serious economic consequences.

What if the husband gets sick or, worse, dies? What if he loses his job? What if the couple divorces?

On top of all that, it’s often difficult for women to return to the workforce after being gone for a few years. Unfortunately, factors such as ageism, sexism and even resentment come into play. Taking three years off can mean earning one-third less than someone who didn’t leave her career.

Are you a better mother if you don’t work? That’s a question only you can answer. But, women, make sure you’re aware of the consequences if you decide to quit your job. I’m not sure I totally agree with Ms. Bennetts because every situation is different, of course, but I think she brings up some valid concerns.

Just because you’re a great career woman doesn’t mean you can’t be a great mom.
