Women Are Primary Breadwinners in 40% of Households, But Are They Happy?

Ask your favorite working mother how her day was. If she talks about her career, chances are, she's pretty happy with her life, according to a new report from Working Mother magazine. If she talks about her job, she's probably not.

Since women are the primary breadwinners in 40 percent of American families, it helps if they're happy. The study found moms who view their work as a career are happier in all aspects the survey measured -- marriage, kids, friendships, salary, respect they command and choice to work -- than women who work primarily for a paycheck.
