If you’re thinking of dropping out of your fancy law job to stay home with the kiddies, I have one word of advice for you: Don’t. Unless you are absolutely certain that you never want a future in Big Law or some other similarly competitive position again, don’t even think about it.

That’s essentially the finding of a new study by Kate Weisshaar, an assistant professor at University of North Carolina at Chapel Hill. In a recent post in the Harvard Business Review blog, Weisshaar writes that employers look askance at stay-at-home moms and dads who try to re-enter the workforce: ”Put simply, stay-at-home parents were about half as likely to get a callback as unemployed parents and only one-third as likely as employed parents.”
