Great highlight of (an update on) those opt-outers: Returning to Work after a Career Break: The Good News.
Especially good news:
“That fact is one of the least well-known, but most critical aspects of career breaks: that people’s view of you is frozen in time. They remember you as you were…”
You know, you can maintain that view of you, over time, too. Social media (Facebook, LinkedIn, Twitter, etc.) — use it and use it well, at-home parents.
