Japan's old calendar called December shiwasu (師走). These two kanji mean "teacher" and "run." The idea was that the last month of the year is so busy that even a staid, starch-shirted professor finds him or herself scurrying around like a rabbit, trying to get everything done on time.

As we hurtle toward 2014, it's time to look back on how the Year of the Snake treated labor. In keeping with the growing trend on TV, blogs and news sites, I've devoted this final edition of the year to a Top 5 list. The Top 5 Labor Pains of 2013 will focus on what really shook things up in terms of labor relations and employment law. In keeping with convention, I'll count backwards.

Note: These are my personal picks and you may question my choices or believe other labor news to be more deserving of inclusion. If so, please don't hesitate to let me know.
