LinkedIn is now giving people the option of adding a career break to their profiles. Instead of having an unexplained time gap between positions, you now have the option of adding a more specific (and appropriate) description of why you were in-between (traditional) jobs.
The options range from those we might expect (Full Time Parenting and Professional Development) to those we might not (Bereavement, Personal Goal Pursuit, Gap Year, Travel and Voluntary Work).
